The First Adder of the Year

It was another blustery day at Pulborough Brooks. The thermals, fleecey socks and wooly hat were firmly on and doing their jobs as I strolled across the reserve this morning, squinting as the sun appeared intermittently from behind the heavy clouds. I stopped at Fattengates for a quick scan of the brambles and was rewarded with two fluorescent male bullfinches, always a welcome sight.

At West Mead, a large group of wigeon were grazing to the right of the water. As the sun came out once more, it highlighted two snipe as they dashed towards the edge of the pool. They spent some time here, preening themselves and generally being quite active which made a change, since snipe seem to favour tucking their heads away and not moving for long periods; at least, they do at Pulborough! I scanned the taller grass where that the wigeon had now vacated and managed to pick out four more snipe, one of which was demonstrating said "tuck-and-sleep" behaviour. Their camouflage is truly amazing when they are stood still, especially among short reed beds, but this was a great opportunity to see them out and on display. It was a treat to see a decent number of pintail, shoveler and shelduck too.

I was keeping a keen eye out for raptors, particularly peregrines after having had successful sightings of them over the past few weeks, but it was slim-pickings today, despite the occasional bursts of sun. Although it was breezy, conditions which might put some birds of prey off, it was ideal for falcons to be out hunting. However, I only had two buzzards, one of which was looking pretty weathered on his right wing and tail. Not that I don't love to see buzzards, particularly when the sun catches their markings. I met up with a fellow volunteer (off-duty) standing with a visitor on the pathway known as "Adder Alley", and for good reason; amazingly, the visitor had located an adult female adder to the left of the path! When I arrived it had disappeared but it soon came back in to view once the sun came out and bathed the grass in light and heat.

(Apologies for the photo quality! These were taken on my phone)

I've actually only seen one other adder before and it was a very young one, only just bigger than an earthworm. This adult was over 2ft in length and I was able to leisurely admire the beautiful diamond pattern on her scales and see her smelling the air with her thin, black tongue. It certainly made up for the lack of raptors!

The track down to Nettley's hide is usually a great place to spot goldcrests and even firecrests. My walk today yielded both species, with a particularly fantastic showing from a firecrest which was flitting around in the open only a foot in front of me. I got lovely clear views of the bold, orange crest, olive body and black eye-stripe. On the same trail, I also caught sight of a green woodpecker as it landed on the trunk of an oak. Once again, this made a nice change as I normally only see the yellow of their rumps as they fly away.

In other birding news, I made it our for my first patch session a couple of weeks ago, guided by my fellow Midhurstian (not sure that's the official title!) Sophie, of The Oak by the Rife blog. It was a beautiful day and Sophie took me on one of her most frequented walks, pointing out where she had seen various species over the years. At one point we were discussing ravens after she received a text from her mum saying she'd seen on fly over the house, and I commented that I had never seen one in the wild (naturally the Tower of London ones don't count). No more than 15 minutes later, we heard the unmistakable cronk-cronk call and were treated to a fantastic over-head sighting of a raven; it even demonstrated the call again as it was directly above us. I might try out this technique on other species I'd love to see: "I have never had a Long-Eared Owl in my garden..."

Greeted by a Grey Wagtail

The weekend just gone was rather a busy one for me. As I discussed in my last post, I held another beach clean-up in Worthing for the MCS Great British Beach Clean on the Saturday which was a great success all round. On Sunday morning, my legs were aching from walking on the pebbles but despite this, I headed over to Pulborough Brooks to start another new volunteer role. I've been a volunteer in RSPB Pulborough's visitor centre since 2013 which has been instrumental in the building of my wildlife knowledge and communication with the public. The opportunity recently came up to join the hides and trails team and I thought it would be a great chance to branch out a bit and get myself more involved with a different aspect of the reserve.

I was taken round the reserve by Graham, another H&T volunteer who has many years of experience and knowledge, and was happy to share it with myself and Ben, another new volunteer. We were extremely lucky with the weather as Saturday's beautiful sunshine carried on which meant there were a few raptors about, using the thermals to their advantage. Our first spot was a sparrowhawk, though we were initially unsure as it was a fair distance away and its flying pattern was slightly out of character. It appeared to be catching insects in flight which is behaviour one would normally expect to see in a hobby, although the wings were the wrong shape for that. In the end, Graham managed to glimpse it in his scope and confirmed it as a sparrowhawk. Obviously one having a funny turn!

My birding knowledge has certainly expanded over the past couple of years but I am nowhere near competent in identification, so I'm always quite pleased when I spot a bird that is a bit trickier and correctly I.D. it straight away. This happened a few times on Sunday; one was a blackcap which generally isn't hard to identify but I don't see them very often; another was a female shoveler nestled among a group of mallards. We had some exciting sightings across the course of the day and the majority of these were at Hanger View where we spent quite a bit of time. Several kestrels were seen flying past and hovering over the North Brooks and one perched itself at the top of a berry-laden bush right in front of our position. It was a pleasure to observe this beautiful raptor bathed in sunlight, calmly preening itself and stretching its wings. I actually didn't realise kestrels had such vibrant orange legs until I saw this one through my binoculars. 

A kingfisher made an appearance, the blue iridescence of its feathers contrasting against the red reeds it was hiding in. Another kestrel was dive-bombing a gliding buzzard in the distance. Two green sandpipers occupied the pond closest to us and we were able to watch them for at least an hour. At one point, they had a bit of a tiff and were chasing each other around in sweeping circles, half flying and half running. The shrubs closer to us were shaking with starlings and juvenile goldfinches, as well as a willow warbler. A couple of jays were picking acorns off the oaks and a green woodpecker flew from one side of the view and back. A cacophony of noise from the canada and greylag geese formed the afternoon's soundtrack. In the furthest pond, huddled between a group of lapwings were at least three dunlin, though the heat haze made it hard to focus on them, even through a scope. 

By far the spot that I was most thrilled about was a grey wagtail. A few visitors had reported seeing a yellow wagtail or two nearby, but the grey appeared in the same pond as the green sandpipers and was easily distinguishable from its yellow cousin. I observed the comical dipping and lifting of the rump that gave the wagtails their name and saw how bright the yellow of its lower belly was. Even though the bird itself wasn't visible without optical assistance from where we stood, the sun kept catching that yellow belly as it moved about, pecking at the sand. It was quite unusual to see the grey wag in a location with still water; they are more commonly found near moving water, such as rivers.

The oak trees directly above us were full up with song birds, including blue and great tits, a nuthatch that could be heard tapping energetically, several long-tailed tits and at least two goldcrests, who's calls were first recognised by Gordon, another volunteer at the reserve who is particularly good with his bird sounds. It seemed as if the nearby robins never stopped singing. 

I was pleasantly surprised with how much we saw and heard in that four-hour period. I'm very much aware that we are entering an exciting time of the year when it comes to birding, with many migrating waders and wildfowl returning from their summer holidays. In that respect, it is a brilliant time for me to be starting on hides and trails. In terms of the temperatures and the high chances of more rain, it isn't! I don't mind that though; if it means I have the chance to be out and about, learning more about wildlife and being able to share my passion with the public, then I'm definitely going to be happy.

Adventures in Wales: Dyfi Osprey Project

I'm certain I've mentioned this before, but I'm going to go ahead and say it again anyway; the best experiences are unplanned. The Wednesday of my week in Wales with my parents had been our planned day to visit Skomer Island but we discovered that strong winds meant the boats weren't running, and so we found ourselves up and abluted very early with no destination. Rather than waste the opportunity, we decided to head north towards Aberystwyth with the intention of visiting the Dyfi Osprey Project. This was around about a two and a half hour drive from our campsite in Haverfordwest so we had originally deemed it too far to travel when planning the holiday but since we'd made an early start and had a picnic already packed, it seemed silly not to go for it. 

I can't express how excited I was at the prospect of seeing ospreys in the flesh. They have been my favourite bird of prey for a while now although I always felt like a bit of cheat saying that when I'd never actually seen one! I follow all of the monitored osprey sites on social media, including those at Rutland Water, Dyfi and the Lake District but from where I live in West Sussex, they are all too far away for me to visit for the day. It had become a dream of mine to see the birds in the flesh, one that I hadn't anticipated fulfilling any time soon. 

The project is located on the Cors Dyfi reserve managed by the Montgomeryshire Wildlife Trust, on the A487 north of Aberystwyth. The reserve itself is not huge but it's beautiful, with lots of vegetation and very dense reedbeds, perfect for spotting warblers. We arrived in the car park and were lucky to find a space, given that it only facilitates 50 cars. When I was speaking to one of the staff there, he did tell me that they are hoping to expand the car park in the future to stop people parking on the main road during the busy season. There is a hide just outside the visitor centre where we spent some time watching the feeders being mobbed by a variety of song birds, including siskins and redpolls, which were both first-time spots for me. 


After some time in the hide, we made our way along the raised wooden walkway, listening to the popping of seed pods as they opened in the heat. The forecast had been spot on; it was a baking day and there was no breeze at all where we were. The skies were clear and perfect for spotting birds of prey. I spotted my first meadow pipit and reed bunting on our walk to the 360° hide, their chirps mixed in with the songs of reed warblers.

Meadow pipit

As we neared the osprey hide, we stopped to watch a reed bunting singing at the top of a shrub. A movement in the sky caught my eye and I brought my binoculars up to focus, and as the sun highlighted a white head, I realised I was seeing an osprey for the first time. I'm not at all ashamed to admit that a shiver went through me as I watched this beautiful bird gliding through the air. It's the first time I've ever had such a strong physical reaction when seeing a new species; it was just so surreal and very special. 



I didn't think to take a photo of the 360° hide which is a shame as it's an impressive structure, constructed from wood and featuring expansive windows giving views of the entire reserve, as the name suggests. When we got there, we were told that Monty, the male, was perched above the nest and that it was Glesni, the female, that we had seen soaring outside. Monty and Glesni have both featured on Springwatch and Autumnwatch in the past, so it was almost like seeing a celebrity, but much, much better! I tried my best not to hog the scopes but I found it almost impossible to tear myself away from the fantastically close view of Monty guarding the nest, where the heads of the three juveniles were just visible. 

Monty perched abover, Glesni on the nest and two of the juveniles either side of her.

We stayed for a long time in the hide and had several enjoyable conversations with the staff and volunteers there. It's wonderful talking to people who are so passionate about birds and wildlife and who really know their stuff. The most fascinating thing I picked up was that the juveniles, once fledged, will instinctively know that they have to migrate, they aren't taught or encouraged by their parents. I find the concept of instinct extremely interesting, especially in a situation like this where these animals just know they have to fly thousands of miles at a certain time without any prompting. 

The juveniles spent some time flapping and stretching their wings. I was told that they were approaching their fledging period and funnily enough, exactly a week after our visit, the oldest chick took her first flight from the nest, closely followed by the other two. It remains Monty's job to continue to bring in fish for feeding until such times as they are ready to migrate; Glesni more or less has no more part in their upbringing. 

There's an open deck area at the back of the observatory, where we sat and had our picnic with undisturbed views of the reserve and surrounding hills. We watched Monty take off and fly towards the left bank of hills before he disappeared over the top, most probably to go fishing again. I was hoping we might see him return with a catch before we left, but he was still gone by the time we came to leave. 


I'm so pleased that the boats to Skomer weren't running that day. Apart from the fact that I think we would have absolutely roasted in the heat had we made it to the island, it meant that I was able to fulfill a dream that I hadn't imagined I'd be able to fulfill for quite some time. The osprey is such a majestic bird and being able to see the Dyfi family in the flesh has just cemented their place at the top of my raptor list.

Falconry Experience at Eagle Heights Wildlife Foundation


I've recently earned myself the nickname of "Bird Girl" from my close family members. Although it could be a lot worse, I can't help imagining myself as some kind of pseudo-superhero and I'm quite thankful that I wasn't presented with a stretchy Lycra suit emblazoned with the initials BG on the front for Christmas last year! What I got instead, from my dad and step-mum, was a Red Letter Days "Introduction to Falconry" experience. Needless to say, my excitement was not very well contained.

Birds of prey fascinate me. They are such a diverse range of species with a huge variety of skills that they have honed and learnt to use to their advantage in the wild. They are the definition of survival of the fittest and that really is something to be in awe of. If you have read my past posts, you may have already picked up on my captivation with raptors; I've certainly mentioned the peregrines enough times! 

Chippy or Sparky the barn owl-I can't remember which!

My raptor experience was booked with a fantastic conservation park called Eagle Heights Wildlife Foundation in Kent. I've visited the park only once before, a couple of years ago, and had a brilliant time so I was thrilled to be going back and getting even closer to their birds. They have over 150 birds of prey as well as a collection of other rescue animals including a camel and a pack of huskies. The flying displays are really well put together, full of information and very entertaining for all ages.

Before starting the experience, myself and my dad managed to catch the first half of the midday flying display. We had the delight of feeling Kayla the Bald Eagle narrowly missing the tops of our heads as she sailed across the audience, watching Mr Butthead (!) the Caracara refusing to use his wings, instead choosing to comically jog around after his trainer Ron, and witnessing the impressive flying skills of Anubis the tribrid Peregrine/Gyr/Saker falcon.

Following a quick spot of lunch, we, and a couple who were also doing an experience day, were met by falconer Emma. She kitted us all out with food bags and flying gloves then introduced us to the four Harris Hawks we would be taking out for the day, following a few all-important safety rules. My hawk Ollie was a juvenile, only about a year and half old, and still had the younger pale brown plumage around his head. He was beautiful and very relaxed, as they all were. 

Once we were all tethered to our hawks, we headed out into the stunning countryside that the centre backs on to. Quite honestly, the weather couldn't have been better, which was a relief since I was convinced to leave my coat behind! We strolled through the fields with the sun beating down on us and a comfortable breeze rustling the feathers of the hawks. 

Ollie the Harris Hawk with Emma

After we had walked through a couple of fields, it was time to untether the birds and start flying them. Emma showed all four of us how to call back the hawks when it was required, then we released the birds up into the trees, where they slowly followed us as we carried on walking. The gentle tinkling of the bells attached to their jesses told us where they were and when they were following, although we made sure we could always see all four animals. They were fitted with transmitters just in case they decided to fly off but that wouldn't have been an ideal situation! Eyes were kept on them at all times.


At times, when all four birds were sat in a tree above us, I felt almost as if I was prey being watched by vultures! I never felt threatened by them, it was just the way they were all intently watching, clearly looking out for signs of food coming out of our bags. So it proved a tricky task to load up our gloves with chicken but keep it out of sight when it came to calling them back. Ollie was particularly cheeky and would snatch the leg from between my fingers before I'd even got hold of his jesses. It took several attempts before I had successfully managed to secure one of the birds in my glove.

Ollie

We carried out several releases and call backs, all with varying degrees of success. Later in the afternoon, all three birds were back on the gloves but Ted, who had gone out of sight, although I could still hear his bell. Ted was easily identified as he had plucked some of his belly feathers out of boredom a few days beforehand, only because it was raining heavily on the day and he wasn't able to fly! Emma spent several minutes calling him and gesturing with food, and eventually he appeared. When we got him back on my glove, we noticed he had blood all over his beak and talons; a possible sign that he had found himself a snack in the form of a mouse while he was in the thicker trees.

We started crossing the field back in the direction of the centre and were serenaded by the unmistakable Skylark's song as we went. I have heard the song many times before and glimpsed the faint shape of the birds high up above the fields in the past but never had a close view of them. This time, I was treated to the sight of maybe six or seven Skylarks much lower down, singing their hearts out. We suspected they had nests in the field we were walking through and that they were singing so vehemently to distract us from finding their eggs/chicks. Not that the larks knew it but we weren't a threat and neither were the four hawks, who were all showing signs of starting to tire after all of the flying they had done.

One thing both my dad and I noticed was that, by the end of the session, we had really grown comfortable with having the hawks so close to us. I think once I had established that these were trained, happy and reasonably docile birds who were not going to attack, I could relax and enjoy the privileges of being at such a close proximity to them. Emma gave each of the hawks a whole chick to eat at the end of the afternoon, before we returned to the Heights. We had our gloved hands out, palm up, so they could eat comfortably and Ted was perched on my thumb, his talons wrapped round loosely. He wasn't hurting me and he wasn't applying any pressure but I was just aware of the power that these birds have and how they must apply that when they are out hunting in the wild. 

Having grown so relaxed with the hawk on my hand, I didn't want to go back! It had been such a wonderful way to spend an afternoon, witnessing four very happy birds in a natural environment. I will point out that birds of prey in the wild can be very lazy. When they are not hunting, they are more likely to be sat in a tree than expending any great amounts of energy. They are treated incredibly well at Eagle Heights and are flown every day when this is possible and, of course, when they want to! You can't force them to do something they don't want to do.

I can't praise this experience highly enough. There wasn't a moment that I didn't enjoy and if I could, I'd do it every day. Our falconer, Emma, was incredibly knowledgeable and patient with us. We even got back to the centre to find tea and cake waiting for us. That's a bonus in my book!

Peregrines Become Parents (Finally!)

It's times like these when it becomes increasingly difficult to work from home. From last Wednesday until Monday, I've had the live stream of the Chichester peregrines permanently playing on my computer while I simultaneously attempted to work on my commissions and keep an eye on those eggs for signs of hatching. I feel I've come to know these birds very well indeed with the amount of viewing time they've had from me!

My patience paid off, although there was one point when I was worried we might not be getting any hatching at all! After another shift in Chi on Thursday with still no positive signs, I woke up on both Friday and Saturday morning with the same thought running through my head: "today is the day." It turns out I was right on the latter but only just. Around about 11:30pm on Saturday night, I was just about to switch off the camera when I saw the female suddenly spring up from her seated position in the nest. She had spent that whole day fidgeting and wriggling about, clucking and peering down so I had an inkling that she knew something was happening.


She sprung up, dipped her head and one moment there were four eggs, the next there was a freshly-hatched chick! She picked it up gently and carried it over to the right of the nestbox briefly, before placing it back among the eggs and settling back down on top. I was thrilled to have caught the moment, the one I had been endlessly watching for for over four days or so. I went to sleep happy. I woke on the Sunday even happier; at 5am, a second chick had hatched!

 The female (L) and male (R) with their two chicks

The thing that has blown me away since this all happened is just how much of a part instinct plays in the cycle. These eggs were laid and the parents knew that they needed to be kept warm through incubation. Then the chicks hatched and without missing a beat, the male began to bring in small prey items which are passed to the female for plucking and feeding to the hatchlings. There was no hesitation or uncertainty. This may well only be this pair's second breeding year but they know exactly what they are doing. 

 One of the first feeds and the female mantles her prey

 It's been a treat to see the feeds taking place every couple of hours. Despite the fact that the male and female divided the incubation period more or less equally between them (the female took over for the nights), now that they have chicks, the female has gone into full "mother mode" and is incredibly reluctant to let the male brood them. The most I have seen him do is half an hour, just enough time for her to stretch her wings. I have particularly enjoyed listening to the amount of communication that goes on. The female and male call to each other loudly when they are trading food. When the female tears off small strips of meat for the chicks, she clucks as a form of encouragement so that they know food is coming. There have been a few moments when the male has flown in with the intention of taking over brooding and the female has remained sitting, but they exchange several "phrases" as if having a conversation. It's fascinating stuff.

By yesterday, the team were beginning to think that, like last year, we would only have the two chicks as the hatching bracket of 28-36 days was closing fast. For more rural peregrines, the bracket is 28-33 days but I've learnt recently that urban falcons have slightly longer, although I don't know the reason for this. This wouldn't have been unusual to only see two out of four eggs hatch out but we were hoping for more. Fortunately, our hoping wasn't for nothing and in the early hours of this morning, a third chick hatched!

 Male (L) and female (R) with chicks

 Fantastic view of the females talons!

I've been going screenshot mad over the past couple of days as it is all a new experience for me and I want to capture as much as I can. I feel so privileged to be observing this process in such a natural, unobtrusive way. To gain insight into the instinctual behaviour of this species without disturbing them is wonderful and being able to share it with the public in the way that we have been is extremely rewarding. 

There is still the matter of the fourth egg. Given that we have now passed day 36, there is very little chance that the fourth will hatch out. I'm writing this at 11pm so I could very well wake up tomorrow morning to see I've been proven wrong! Either way, the next few weeks are going to be equally as fascinating to observe. At this stage, the chicks closely resemble three balls of cotton wool more than the high-speed, streamlined falcons they will grow up to be. They are going to be eating enough food to double their weight every 7 days so that by week 6, they will be the same size as their parents and ready for fledging. Never a dull day with the peregrines; watch this space!

Chichester Chicks and Intruders!


Today marked day 30 of incubation in the Chichester peregrine nest. I was on volunteering duty and really felt like today would be the day we would finally begin to see signs of hatching. Each time there was a glimpse of the eggs as the parents shifted around on the nest, myself and the rest of the RSPB team would be peering intently for any suggestions of pipping, which is when the chicks begin to make small holes in the shell using their "egg tooth". Even on our high-quality HD camera, we saw none. The female was incredibly fidgety at times, struggling to get comfortable on the eggs on several occasions and this is out of character for her, as she would normally be straight down on them with one little wriggle before settling in for a few hours of incubation. We were almost convinced that the fidgeting was a positive sign of imminent hatching but so far, we haven't been proved correct!

 A poor-quality snap of the male during a shift-swap with the female this morning

This didn't mean the day was a wash-out. In fact it was the opposite if we are being literal, as the sun was definitely making up for yesterday's horrifically strong winds and rain. The warm weather seemed to bring a lot of other feathered species out to play, including a lone sparrowhawk early on in the day. It didn't hang around but simply drifted across the city before heading off to the East. A flock of six or seven swifts spent the day twisting and diving through the sky just above our marquee, their scree scree calls punctuating our conversations with the visitors. One of them showed interest in an old nesting sight set inside the brickwork of the building connected to the cafe which suggests that hopefully they will choose to nest their again this year. This will be a fantastic bonus sight to see for visitors, volunteers and staff alike.

The biggest event of the day was the return of an intruding female peregrine. Over the past few weeks, there have been two different individuals identified, both female, although one is a juvenile, and both have been seen off by the parents. Today, the intruder arrived above us, followed closely by our male who had only come off the nest an hour and a half before this appearance. He was absolutely intent on getting rid of her and managed to execute several collisions with her which seemed to do the trick. It was quite a spectacle and I was pleased to have been there to see it as I've managed to miss all previous intruder occurrences this year! There was a small group of the public with us at the time who were all thrilled to see it too.

I think we were all surprised that there were not more buzzards and red kites out enjoying the thermals during the day. There were none of the latter but of the former there were only two appearances. During the first half of the day, a pair were gliding very high up showing no interest in the nest site and this resulted in only a brief spell of chatter from the female on the nest. Another one arrived in the afternoon, flying lower this time and with the male peregrine in tow. He didn't need to waste his energy on chasing the buzzard off as a rather brave herring gull had this covered. I was quite amazed at how close the gull was getting, as he swooped down on the raptor but never made contact. At the same time, I was presented with my first ever example of a peregrine falcon in a stoop. As the buzzard headed away from the site, the male peregrine remained airborne and quite suddenly he went from a glide to tucking his wings tightly in to his body and dropping into the characteristic dive. It wasn't a fully vertical one but still fairly steep and it brought him quickly and neatly on to the North side of the cathedral spire, out of our eye line.

The garden of the Cloister's Cafe, where we are set up, is a haven for various species of songbird, many of which are simply not fussed by the presence of humans. A wren, who has nested in the roots of the lilac bushes, spent much of the day to-ing and fro-ing with a full beak. Based on the frequency it was visiting, it was determined that it must be feeding chicks. We were serenaded all day by a very chatty blackbird who spent most of the time perched on the wall beside our marquee. At one point he flew across the garden so low that he almost brushed my head-not an easy task given that I'm only 5' 3"! A pair of blue tits hung from the bottom of low-hanging tree branches, picking off insects from the leaves. A dunnock jumped around the undergrowth before flying to sit on top of a low roof and released a brief but beautiful stream of song. A charm of eight or so goldfinch were also in the trees for some time, chattering and chasing each other through the air.

So although we are still waiting oh so patiently for the tiniest sign that these chicks are starting to arrive, today was certainly not uneventful. It is heartening to see such a broad range of species inhabiting a space that is only the size of an average suburban back garden.

Chichester Cathedral Peregrine Project

This week I started work in a new volunteering role for the RSPB. As you may or may not know, I have been a volunteer at the Pulborough Brooks reserve since 2013, where I work once a week in the visitor centre. It is a varied role with the focus being on retail although I also do a certain amount of meeting and greeting, and giving general advice on wildlife and nature. Despite the fact that I don't very often get the opportunity to go out on to the reserve itself, I enjoy working there and the reserve team are a friendly bunch. That said, I've been looking for other volunteer roles that would take me out into the field a bit more and give me a chance to build up some new skills, so I registered my interest in the Peregrine Falcon monitoring project that the RSPB runs annually from Chichester Cathedral.

Peregrine falcons have been nesting in Chichester Cathedral since 2001 and the RSPB has observed and recorded their progress every year since then. The birds nest in one of the turrets which contains a specially-designed nest box provided by the Sussex Ornithological Society. Traditionally, peregrines would nest on cliff edges, creating shallow scrapes in the ground using no nesting material at all. This leaves them open to the high risk of their eggs rolling off the cliffs and so they have come to realise that cathedrals across the country provide much safer, lower-risk nest sites.

The peregrines are nesting in the turret on the right.

The live webcam has been streaming for several weeks now and the peregrines have laid four eggs. This number of eggs was no surprise as the female laid the same last year and she will always lay the same amount; the number of eggs laid in the first year of breeding determines how many she will lay for the rest of her life. This doesn't necessarily mean that all four will hatch out into nestlings. 2014 saw two of the four eggs hatch but this was likely down to the erratic laying pattern of the female. Normally laying would be completed within a week, with 24-48 hours between each egg, but it took a fortnight for all eggs to finally be laid. This year, however, the laying pattern was much more as it should have been, so for that reason, the hopes are that at least three if not all of the eggs will hatch. 


My first day as a Public Events Assistant on the project was unseasonably warm and I was quite thankful to be on webcam duty and spending the day in the cool shade of the marquee. I felt a certain amount of pressure as I know the majority of volunteers involved this year are returning participants and so have plenty of knowledge to share from past breeding seasons, in comparison to my limited knowledge-base and experience. Once I got talking to the public, I felt much more at ease and thoroughly enjoyed sharing the few facts I had with interested parties. I know I'll pick up plenty more as I go along, particularly from listening to other staff and volunteers. I certainly got a thrill out of seeing the expressions of wonder and excitement on the visitors' faces. 

Until the eggs actually hatch, there is actually a limit to what we are able to show visitors. The female does the majority of incubation and the male is supposed to bring her food and take over about 15% of the work. This particular pair, however, have been behaving in slight contradiction to this. They have been taking shifts of around four or five hours each on the nest and going off to find their own food. On Wednesday, when I was working there, a wake of buzzards circled high up above the cathedral, riding thermals and showing no interest in the nest site. They were seen off by the female with a few vertical attacks, before she took over brooding at around 11am and spent the next few hours exposed to the direct sunlight and heat of the day. As birds don't have sweat glands and so cannot cool down by releasing moisture as we would, they have to "pant" in order to expel the heat from their bodies and regulate their temperature. The female was panting heavily for the entirety of her shift and I did feel for her, having the task of keeping her eggs warm and herself cool simultaneously! No easy task. When the male eventually returned around 3pm, the sun had moved round and shade had crossed most of the nest box, so he was much more comfortable than his partner and only demonstrated panting for a short time. 
  

The fourth egg was laid on 7th of April so, based on the 28-33 day incubation period, we are estimating hatching will begin around the 5th of May. It's at that point that having a 24-hour live stream of the nest could prove very distracting, particularly when there is work waiting to be done! Here's hoping that all four eggs hatch out.

Why I Love Birds of Prey

A few days after Christmas, I went for a ramble along one of my favourite local routes, in an attempt to clear the festive fuzz from my brain and breathe some turkey-free air. It was what I consider to be the perfect Winter's day; the sky was clear, the sun was blazing and the air was crisp. The lack of clouds was a blessing for me as it made spotting birds a lot easier. I saw a pair of redwings chasing each other around an oak tree then a little further down the lane, another one take sudden flight from the hedgerow and fly low across the field. The trees were bustling with the usual suspects; blue and great tits, blackbirds, woodpigeon. Robins eyed me from the branches and carrion crows littered the fields.

My highlight, though, was a bird I never tire of seeing, or hearing for that matter, since on most occasions I hear them before laying eyes on them. The unmistakable caw of a buzzard drew my gaze high up and I had to shield the sun with my hand in order to fully focus on the three raptors circling above. I am so fortunate to get frequent sightings of buzzards where I live and a great number of these have been directly above our house. Once, an adult flew so low across the house that I could see the pale under-feathers on its wings.

On this occasion, the birds were obviously hunting, gliding effortlessly in large circles above the fields. One dropped down low to the treetops and the crows feeding in the fields became agitated by its presence, taking flight and cawwing loudly. I carried on up the lane, following the buzzards as they moved higher and nearer to the woods surrounding my house. I lost sight of them briefly but could still hear their calls echoing through the trees. When I next spotted them, I had more or less reached home; the three birds were performing acrobatics between themselves above the fields neighbouring the house. I watched two of them spin through the air, attached to one another by their talons for only a moment before breaking apart. I presumed one of two things was going on; either they were fighting with each other or they were passing food between their feet. I couldn't say for sure since I was lacking binoculars and they were too high for any specifics to be made out.

As I said, I never tire of seeing and hearing them and I doubt I ever will. It's a particular joy in the Summer, when they are extremely active and I'm guaranteed to at least hear the buzzard call a few times in a day. There's something about them that is mesmerising and I think that's a view that I carry through to all birds of prey. They are fascinating to see in action, whether I see a tawny owl drop from the low branches in front of me while I'm driving at night or I'm marvelling at the brilliant strength of a kestrel hovering in high winds.

Rather oddly, my favourite raptor (a word that is the Latin for "to seize and carry away", as I discovered today) is one I've never actually seen in the flesh, and that is the osprey. I'm always fascinated whenever I catch segments on tv showing them in action; the coverage of Monty and his mate on Springwatch made for wonderful watching. They are such striking birds and it is definitely a dream of mine to see at least one in its natural habitat.

I think it is the strength and intelligence of raptors that has me so besotted. Owls may not be able to turn their heads the full 360° and might not be quite as wise as they are often portrayed in children's books, but their brilliantly-honed hunting skills are enough to set them apart. The marsh harrier can dismember and eat a dragonfly while on the wing and a vertically-plummeting peregrine reaches unbelievable speeds; these are birds that are experts in their fields.

I was lucky enough to receive a falconry experience as one of my Christmas gifts and I am so excited. I have handled owls in the past but only small breeds so I'm looking forward to learning more about other birds of prey and getting some hands-on experience.
