RSPB Leighton Moss 17th February 2013

On a day that was truly beginning to feel like spring I took myself up to my favourite wetland in the whole of North Lancashire, the RSPB’s Leighton Moss, which sits in a valley close to Morecambe Bay, in the shadow of Warton Crag, in the Silverdale AONB.  I took with me the excuse of going to look for literature, I am set to do my dissertation project up on Warton Crag, looking at butterflies in the summer.  Before I reached the car park I wondered if there was a big twitch on, such were the numbers of people lugging their scopes up the road. It turned out the only particular rarity in the sky above Leighton Moss was the sun. It had brought the people out on a sunny Sunday afternoon for sure. Although I had arrived alone this would not be a day of birding with solitude, and the reserve hosted quite a volume of people!  The sound of distant shooting also broke my tranquillity a little bit, although my inner hippy was calmed a little when a volunteer reassured me today’s shoot was for Clay Pigeons.

I paused initially at the Moss Passerine Experience, or feeding station as its more popularly known, and watched the handsome Chaffinches, looking very bright and sharply coloured in the sunshine. There was a Brambling about, a close relative of the chaffinch and relatively scarce winter visitor.  Numbers vary from winter to winter, but they are about every year, apparently displaying very little site fidelity, and they are irruptive.  When in small numbers they tend to follow flocks of chaffinches, and this, a smart female with resplendent orange shoulder flashes, was doing just that. She would appear on one of the bird feeders for a couple of seconds before being off in a blur of black, orange and white. Bramblings always have distinctive bright white rumps, which are usually a dull green in Chaffinches.

Also around the feeders were the obligatory pair of bullfinches, the male with his bright, unmistakeable pink breast, perched openly, even allowing for a couple of blurry photographs in one of the trees. The female is just as pretty but a little more subdued in markings. Bullfinches are shy birds and feeding stations like this present an unusual opportunity to get close to them. A feeder with several ports at which the birds could land on it was squabbled over by chaffinches, but the Brambling appeared able to chase them off, and among the assembled spectators getting photos of unusual combinations of passerines on this feeder  became a pastime.  Goldfinch, Robin and Dunnock were also to be seen on the feeders.

I wandered down to the public hide, in the hope of catching up with an Otter or a Bittern, both of which have been seen there, the former apparently this morning according to a lady with a posh scope.  I saw neither, but there were a couple of smart Greater Black Backed Gulls munching on a tasty looking chunk of Perch they’d managed to get their claws into. A few cormorants shared a shingle island with them, and the telescope (hooray I got my new toy back!) picked out some roosting Lapwing behind them. I moved on to the lower hide, from which one of the Marsh Harriers, an old female, could be seen quartering over the reeds. The coots were chasing each other about, and I scanned the distant flocks of Tufted Duck for Scaup, fruitlessly, although there was a female Pochard in amongst them. A pair of Great Crested Grebes bobbed and nodded elegantly at each other. I’ve only seen the famously romantic weed pass in which Grebes indulge once, and was hoping that this amorous duo might perform for the camera, but watching their elegant bobbing and mirroring display was beauty enough. On my return stroll through the reindeer-lichen and Jew’s ear bedecked trees,  I once again made the acquaintance of the friendly, and particularly gorgeous, cock Pheasant who hangs out up there.  He posed for a couple of photos before weight of human traffic on the little causeway, and an alarming pheasant out on the shooting estate next door, sent him scurrying for the shelter of the enormous reed beds.

Freindly Pheasant

Spring was again in the air as robins could be seen doing the tail cocking and chasing but not with real intent thing, indicating breeding birds sussing each other out for mate potential despite their still strong and fiercely territorial instincts.

Once back at the visitors centre I grabbed a cup of coffee, and chatted to one of the staff about the butterflies of Warton Crag. Bring on the summer, there are Scotch Argus and High Brown Fritillary in addition to the lovely little Northern Brown Argus, which I hope to help a little through the application of science this summer, to be seen! Butterflies over coffee aside, I made my way to the Tim Jackson hide, which lies at the Western end of the main reserve. I noticed a Marsh Tit on a branch as I walked through the woods. To my surprise another perched a few feet from it. The first bird darted down and into a small gap in a moss covered log, and appeared to retrieve something. It’s partner then did the same, until a chaffinch chased it away. The chaffinch was chased off by a Dunnock, which retreated when a Nuthatch arrived. The penny soon dropped that someone had placed some sunflower seeds inside the log, and it was on these that these disparate passerines were feeding. The Marsh tits returned breifly until the prettiest blue tits ever chased them off, feisty little birds that they are.  I watched for a few minutes and, even in the dim light of the woods, managed to rattle off a few photos of the passerines as they came and went, usually pursuing each other as they did so. 

Marsh Tit

The Tim Jackson hide revealed a Little Egret and another quartering Marsh Harrier, and the usual selection of ducks.  The low sun through the window made birding tricky and I decided to use the last hour of fading light to check out the pools on the salt marsh from the Eric Morecambe hide. The car park bears dire warnings of car thieves, but I parked up and wandered on anyway. The sun was setting over the flat expanse of salt marsh down to the edge of Morecambe Bay. Another Egret could be seen standing about beside the reeds, and there were numerous handsome pintail about on the water. A Marsh Harrier scattered them, but as the birds settled back in, there was a pair of Avocets among them. These beautiful black and white waders apparently breed here, beside the expansive bay. As the sun dropped below the horizon, lighting up a red sky streaked with cirrus clouds and air trails, I was struggling to separate waders in the settling gloom, but the little cluster still active consisted of two Redshank, two Spotted Redshank and a Greenshank.

I walked back slowly toward the car, with my scope slung over my shoulder. I became aware of a shape, stock still against the horizon, on top of the ridge. It was a deer. I hadn’t seen one here since my and Natalie’s encounter with one at the Moss some time ago. The animal was picked out against the red sky, and it stood stock still, presumably hoping in stillness lay invisibility. It lifted its head and shook its ears.

The Falcons of Manchester

Whilst my rant about the perilous situation facing many raptors in the UK at this stage, I have to write about my recent visit to Manchester where, in the heart of the city, I got some wonderful views of some wonderful birds of prey, and was a witness to their family life, on a ledge overhanging the river Irwell as it creeps sluggishly between the boroughs of Manchester and Salford.

On the day after my mate Tom’s birthday, we went over to the house of a pair of good friends of ours, a couple who live in one of the impressive, rather new “dual use” tower blocks in the city centre, overlooking the Irwell and the Arndale centre, as soulless a shopping centre as one could hope to find, and the wider city. From the 23^rd floor the city spreads out before you, its smart, red brick buildings dating back to Industrial Revolution expansion sitting side by side with glass office blocks, the 47 story Beetham Tower and, in the distance, older tower blocks sitting on the outskirts of the city, with rolling hills to the horizon. From here, on a clear day, one can see the Jodrell Bank observatory, and a bridge in Runcorn, Liverpool.  As we disembarked from the lift, the window which faced us briefly framed the shape of a Peregrine, its buff coloured underside indicating it was a juvenile.  A couple of pigeons rocketed through our view, obviously recognising the threatening shape above them, changing direction and disappearing from sight. The Peregrine did not stoop after them.

We made our way in to our friends’ flat where we were made welcome, and we sat by the window. We were pointed to a mossy, dark patch, on a ledge beneath the roof of the smart, red brick building opposite. The ledge, on inspection with the binoculars, turned out to be covered in feathers. Many of these were white and our friend reported having seen the Peregrines taking Black-Headed Gulls back to the ledge.  We did not have to wait long for the birds to return. Reports from the RSPB online suggested four chicks had fledged and were being fed by two adults. An adult Peregrine, we assumed it must be the female, the larger of the sexes in this and most raptor species, landed on the ledge, holding in its talons the grey body of a feral pigeon.  The adult was a smart bird indeed, with a slate-black back, jet black crown and facial markings, and a yellow cere and eye ring giving a fierce expression. For a falcon it is broad bodied, chunky even, but lacks none of the grace of its smaller and slighter relatives. Two juveniles, one distinctly smaller than the other, follow their mother onto the ledge. The juveniles are greyer than their parents, with a hint of russet brown in the crown, and very much beige, rather than white undersides. In flight they already look like falcons, but when perching their youth is plain to see. The feathers on their undersides still look fluffy, and they lack the striking yellow facial features of the adults. For now she just stands over the pigeon, which appeared initially to be struggling, but quickly becomes still as she begins to pluck it. The youngsters look intrigued but wait patiently, occasionally reaching towards the female. Within a few minutes, she has cleared sufficient of the late pigeon’s feathers and begins to offer it, in small pieces as if to a nestling, to her offspring, amid a loud chorus of shrill begging calls from the youngsters. A male and female juvenile sit in front of her, and a few seconds later, another smaller juvenile arrives. The largest juvenile appeared to be receiving most of the food, but the others are fed too. The process of delicately removing small fragments of meat and passing them to members of her brood continues for several minutes, before she is off again, leaving the young to share the meat among themselves. The two larger siblings go in for the largest piece of meat, but a wing or some other substantial section of pigeon remains and, furtively, the smallest juvenile approached and dragged it away, feeding in peace a few metres from his siblings.  The process of breaking down and eating the pigeon has, rather to my surprise, taken the birds about an hour, an hour of squawking begging noises. Feathers from the pigeon are carried away on the breeze.

Another hour passes, and two of the youngsters remain on the ledge for some time, one of them, the smallest, laying down on it as if still in the nest. Raptors incubate their eggs as soon as they are laid, so the oldest chick gets a few days development in before the last youngster has hatched. The older chicks tend to dominate the younger ones, and in poor years, it is often just the oldest, or two oldest, chicks which survive. This juvenile though seemed strong enough, we’d seen him eating and holding his own, so, although some of us were concerned by his odd behaviour in lying around on his belly, wings hanging by his sides, I have no reason to believe his chances now are much slimmer than those of his siblings. Part of the difference in size at this stage could well be due to sexual dimorphism as much as age nutrition, and I do tend to think of what we saw as one female and two male youngsters.

An hour later the adult female returned with another pigeon for her hungry brood, two of which, the smaller youngsters, have waited patiently on the ledge for her. From somewhere, the large, and somewhat ungainly, female youngster appears as well.  Puffed up against the cold, she looks awkward, somewhere between being an adorable, fluffy chick and a streamlined, elegant, and deadly adult peregrine.  Her brothers, squawking, have no such pretences of adulthood about them. One could almost be forgiven for making “squee” noises in their presence. Almost.  The adult begins delicately feeding one of the young males, but their big sister barges them out of the way. At one point the cheeky youngster is engaged in a tug of war with her mother, apparently trying to wrestle the pigeon from her, or at least help to break it into more manageable chunks.   The adult female eventually turns her back on the youngster and covers the kill with her wings, offering a little to the smallest male who seems constantly to be standing behind her, keeping his distance from his siblings. Eventually the big juvenile works out what is going on and moves around to compete with her brother. The tug of war is briefly resumed, after which the female flies off, not to return that evening, leaving the youngsters to sort out the food between them. There is plenty left for the smaller juveniles once the young female is satisfied. Again, they make the meal last well over an hour, and they are still feeding after we’d had our dinner and Birthday Cake. When we look back the two little males are still there, but the young female has obviously left, perhaps to join her parents at a roosting site somewhere. We didn’t see the juveniles leave, but as the light faded, and the sunset shone off the glass Beetham Tower, they did leave the ledge, presumably to somewhere to roost and spend the night.  We took a taxi back to Tom’s flat in Hulme not long after.

The Peregrines in Manchester are not unique, a pair roost sometimes on the Tate Modern here in London, and Bath, Lincoln and several other cities also host breeding pairs. They are not harassed, the street pigeons are nobodies sport, and many welcome a bird which can, perhaps, manage their numbers, and volunteers are often forthcoming to watch the nests and guard against would-be egg collectors, or rescue the juveniles when they fall out. Their success is part of the partial recovery witnessed since the banning of DDT and protection from persecution, and Peregrines, which are cliff nesters, are well suited by towns which offer concrete substitutes for their natural nesting sites. Feral Pigeons, too, are descended from wild ancestors which bred on sea cliffs. Their iconic beauty makes them treasured, both by local experts and by nature-deprived urbanites, and cities offer something of a refuge from the human threats presented by the countryside.
