Catching the flycatchers

They sit rather upright, like they are sitting to attention, alert and ready. Their eyes are large, and their short but broad bill has whiskers around the base to help catch the flying insects they feed on. These agile little birds take their prey on the wing, dashing out from a branch, snatching prey mid-air before returning to their perch. They are known as Flycatchers. In Britain we have two regular species, both of which are migrants, appearing in the spring, nesting through our summer and then heading south to Africa for winter. 

The Spotted Flycatcher, could be called the striated flycatcher, or the boring, dullish browney-grey flycatcher. At first sight they may appear just that, a little brownish grey bird with a few streaks. But look closer, and you see the large, dark eye, the pale white underparts with the subtle soft brown streaks. Its back and wings darker with delicate striations on the head. Then just sit and watch. They are wonderful to watch. Sitting patiently on a branch, telegraph wire, or edge of building… then darting out into the sky, almost hovering mid-air sometimes, or dashing around in pursuit of prey. Then back to sitting and watching, the picture of calm following the frenzy of activity. 


The subtly beautiful Spotted Flycatcher

It was one Sunday afternoon in June that saw us sipping tea and eating kindly offered biscuits while watching a pair of Spotted Flycatchers busily feeding and coming to and fro from their nest on a ledge under the eaves of a barn. We had been invited to see if we could catch and ring the birds as part of the BTOs wider ringing scheme. Although just up the road from us, we do not get too many opportunities to ring adult Spotted Flycatchers and were only too happy to take up the offer. With the birds busy feeding chicks it was not too long before the one, and then the other were caught in our strategically placed net. The process was quick, we are old hands now, and it is not long before the birds are back catching insects and feeding their chicks. Just a little time though to admire the subtle beauty of these little birds. 

The other species is the Pied Flycatcher. Much more of a western UK bird, we do not see them much at home in the East of England. But travel west and we have often been found helping out with nest box monitoring projects for these charming little, black and white birds in the sloping woods of Wales. It is not however a bird one expects to catch when mist netting in your parents-in-laws garden. Namely because we are mostly catching birds that come into the seed and nut feeders to eat, and Pied Flycatchers like the Spotted ones prefer their food a little more wriggly, flying, and alive. So when Lee picked a rather dull brown bird out of the net it took us a moment to realise what it was! Females and young Pied Flycatchers tend to be browner than the striking black and white males. But there are still the Flycatcher features of short but broad bill, large eyes, and in this case the white patches on the wing and tail telling us it is a Pied. In fact it was a bird of the year, hatched probably only a few months before in one of the surrounding woodlands. But to see it, let alone catch it in the garden is quite something else! 

The unexpected Pied Flycatcher caught in the garden!

The House Martins

Finally a dry, sunny, warm Sunday morning. Through a bright blue sky with only a few white fluffy clouds soar numerous, small, dark pointy winged birds with forked tails. As they twist and turn against the sky a brilliant white belly and rump flash against the dark back and wings. Their calls fill the air. To me it sounds like someone blowing short raspberries, Robyn in particular does a very good impression. It is in fact a short chirrup, but I like the analogy of my daughter blowing raspberries better! There are twenty or so of these small birds dashing through the warm morning. In groups they dip low and then shoot up under the eaves of the small brick cottage sitting near to farm buildings and open ground. Looking up under the eaves there are a dozen or so small, round, muddy brown blobs attached to the underside with a small dark hole. The birds are House Martins, and with the reed beds at Cranwich completely flooded with limited access we decided to try our luck at trying to catch some of these gorgeous little birds. 

The distinctive House Martin

In the same way we caught Swifts, we now hoist up a net in front of the eaves and the House Martin nests. As the birds drop out of the nest they invariably fall into the pockets of mist net and we are able to extract them safely. 

Up close they are not merely a black and white bird. The feathers on the back are glossy dark bluish purple, the contrast with the white rump and belly is striking. But the very best feature of House Martins are their feathered legs, right the way down to the claws on their toes. 

Up close to the House Martin

As with the Swifts one might ask the question, why go to this much trouble to try and catch House Martins? Well sadly, like the Swifts, House Martins are Amber listed on the Birds of Conservation Concern and has undergone a moderate decline in numbers. 

House Martins are a summer breeder, spending the winter south of the Sahara in Africa. They arrive from April, and although many do not start breeding immediately very soon they begin to build their little mud nests, often repairing old nests.  It is a delight to see small groups of chattering House Martins at muddy pools of water during the early summer, collecting their beakfuls of mud before swooping up to careful place them to form a the muddy shell which is then lined with soft feathers. One of problems is the lack of nesting spaces with modern buildings and the removal of nests from houses. It is illegal to remove House Martin nests during the breeding season, although many are still unfortunately destroyed because of the issue of the bird’s droppings. 

House Martin chicks peeking from the nest

Such is the concern with the decline in House Martins nesting in the UK, especially in England, the British Trust for Ornithology is running a National Survey of House Martins to try and establish reliable population estimates, investigate how the population is distributed and look at the position of nests, timing and number of broods. If you would like to find out more about the survey, and maybe even make a donation to help fund the research then please check out the BTO website

For us we now have the exciting opportunity of a breeding colony of House Martins that we can monitor on a regular basis.

If you go down to the woods today...

Nope we didn’t have to go in disguise and there were not all the teddy bears having a picnic, but this time we were definitely in for a big surprise. 

Sunlight from a golden evening streams through the trees, the dried crunchy leaves and needles scattered on the forest floor glow in the dappled sunlight. The trees are bushing out with bright green leaves, mixing with dark evergreens of the pine trees. A rustle in the fallen leaves and two men appear from the open grassy track, carrying a ladder, and head into the shade of the trees. They move as quietly as possible, carrying their load. Manoeuvring the ladder against one of the tall trees, one begins to climb to the large nesting box attached to its trunk. With care he opens the side hatch and peers in. The box is a Tawny Owl nest box, one of 20 put up around the Forest in a new monitoring project. 

Sunlight streams through as the guys check the box

At the bottom of the box on top of the fresh sawdust placed on its wooden floor, is a deep cosy nest of greyish, soft down and hidden beneath a small layer of feathers are 10 creamy eggs.  

Here is the surprise. The eggs do not belong to Tawny Owl, or even Stock Dove perhaps the other species expected to inhabit the boxes. They do not even belong to Jackdaw, although that would be unusual given the location within the Forest. No, the nest belongs to a Mandarin. A beautifully exotic duck whose usual range is in East Asia but that was introduced in the early 20th Century and is now a naturalised resident. 

It seems odd, a duck nesting in a tree cavity. But there are many that do, including our native Goldeneye.

But there it is all nestled within the squared walls of our box. This time the female is not present and has carefully covered the eggs to keep them warm in her absence. Carefully the ladder is removed and the team retreats, we will return again to check the nest again with the hope of catching the female as she leaves, but also to check that the ducklings have climbed out OK. For that is how it must be, the ducklings will claw up the inner wall of the cavity and launch themselves out of the hole! Good job they are so soft and ‘fluffy’!

A few days later and the glorious sunshine had vanished to be replaced by a rather dull, grey morning. But once again, moving softly and quietly between the trees and over the rustling leaves the team with the ladder returns to the tree and the box. This time we are in luck, the female is in the box and we are able to catch her. What a beautiful bird. While the male may have all the flashy colours, the subtle beauty of the soft greyish brown feathers, mottled chest and big dark eye of the female is captivating. 

The beautiful female Mandarin

We let the female go with an extra bit of bling in the form of a uniquely identifiable ring. She will return to her nest and very soon those little ducklings will be making that leap of faith. It’s then a long walk through the forest leaf litter and grassy tracks to the nearest water of the river.

Stanley

On 31st May 2014, on a very misty, very early morning, I caught my first adult cuckoo. He was a stunning bird, and as well as having a metal ring with a unique number this cuckoo was also fitted with a satellite transmitter as part of a BTO project. I wrote a story about that morning called To Catch a Cuckoo, and at the end of that post I asked where would this cuckoo go, how would he fair during his migration south and hopeful return? The bird was named Stanley by generous sponsors Derek and Maggie Washington. 

The magnificent Stanley

Well, by June 2014 Stanley was off! He was over the English Channel and heading south. It is one of the interesting results the tagging project is showing, male cuckoos in particular do no hang around, and very quickly start heading south. By August he was across the Sahara and recovering from the crossing in the dry regions of Nigeria and Cameroon. By September 2014 he had moved further south over the Equator into the rainforest block of Congo and the Democratic Republic of Congo. Here he stayed until starting his northerly migration in January 2015. Heading northwards through West Africa, Stanley arrived in southern Spain in April 2015 and returned to the UK by the end of the month. He was the third of the tagged cuckoos to arrive back, but perhaps a little oddly arrived in Cornwall before heading back to his breeding grounds in Norfolk. Once again Stanley did not stay long, and by mid-June he was in southern France heading south. He arrived in Africa by the middle of July, and by September he was back in the Congo rainforest in the same area where he had spent the previous winter. By March 2016 he was well on his way north and west, and the race with the other tagged cuckoos was on! Who would be first back this time? Early April and Stanley raced over the Sahara and then the Mediterranean, hot on the heels of Vigilamus who was leading the race of the tagged cuckoos. April 21st 2016 and Stanley had won the race! He was the first of the tagged cuckoos to return to the UK in 2016! Whoop! Even more interesting is that once again he first touched down on English soil in the south west! This time Devon. By the 22nd he was back in Norfolk and near to Cranwich!

Such wonderful data is coming back from the satellite tagging, more that we could get from just metal ringing alone. The map on the BTO’s website shows that Stanley tends to head straight down through Italy and across the Sahara on his way south. While on his return he heads northwest into West Africa before heading across the Sahara and back through southern Spain. So far he always seems to make landfall in southwest England before heading northeast to Norfolk.

In the time since I caught Stanley and fitted his metal ring things have changed for me. My life has turned upside down, in a very good way, with the arrival of my little Robyn. But I have continued to catch and ring birds. I have not however held an adult cuckoo in that time.  Stanley, of course is not the only cuckoo to be back in the UK and Norfolk. My first cuckoo of the year was at our ringing site, near to Stanley’s breeding ground, on the 17th April. Then just yesterday, at the next ringing session again a cuckoo could be heard. This time, with the Robyn alarm waking us extra early we took the opportunity to set a net in the hope we might catch another cuckoo. It was not looking great, with the net remaining empty all morning and with a cuckoo tantalising us in the trees nearby. In typical fashion though the last check revealed a rather large looking grey bird in the bottom shelf. For the first time since Stanley almost two years before I had an adult male cuckoo in the hand! While this cuckoo does not have a satellite tag to tell us all the fine details of his movements, he does have a metal ring which if recovered will certainly contribute to the knowledge we are building of these incredible birds. 

The equally stunning cuckoo caught today...


What a bird!

A Snipe's Tale 2: The Return of Jack

There have been two tales of snipe for Wild Barley. The first the story of a Common Snipe ringed at our site in Cranwich and recovered in northern Spain and the second the story of both Common and Jack Snipe caught and ringed in North Wiltshire. They may also may a cameo appearance in the stories from The Gambia, but as you can tell we do not usually catch Snipe in Norfolk. And we are not alone. In 2014 only one Snipe was ringed in the whole of Norfolk, and no Jack Snipe! You have to go right back to 2009 to find the last Jack Snipe ringed in Norfolk. So when scouting out a new site at a local farm and the distinct call of not only Snipe but Jack Snipe comes from tufts of grass and reed surrounding pools it immediately piques the interest of whether we could catch them. The experience of ringing with others know becomes invaluable. Those opportunities to learn and watch from other ringers to have caught Snipe before, both in The Gambia and North Wiltshire, provide invaluable knowledge and ideas. 

Just before dusk, with the sun heading for the horizon following a cool, very early spring day, nets were set around one of the farms pools. The idea was to catch any birds coming into the edges of the pools to roost. Dusk meant the nets would not be so visible to birds that have such good eyesight. 

Sunset over the site

There was no guarantee it would work. There never is. But luck, or knowledge, was on our side and the return to the nets revealed not one, but three Jack Snipe! 

These three, along with the rest of the wintering Jack Snipe population in the UK will soon be hearing off to Scandinavia and Russia to breed. But at least now a very small (OK a teeny tiny) proportion of the Norfolk wintering population have rings on and so there is always a chance they will be recovered and that might reveal where exactly there are going to breed. Just to have them in the hand provides a unique opportunity to study aspects of their moult and biology and ultimately to contribute to the knowledge of this species. 

It is a privilege to hold any bird in the hand, but to hold those that are rarely caught is extra special. So it is a huge congratulations to Lee for catching three of these wonderful birds.

Ringers to the Rescue

It happens more often that you might think. Birds getting into buildings. It could occur for a number of reasons, perhaps they find their way in for a warm, dark place to roost for the night. In extremely cold conditions, a warm dark building has a particular allure. It might be they are chasing food, a small bird, a small mammal. While in some buildings and for some birds this is no problem. Think of barn owls nesting and roosting in farm outbuildings; swallows nesting in stables; robins nesting in sheds. But sometimes it is not in the grand plan. A chase into a building or a warm place to sleep results in a bird becoming trapped amongst human activity. These are no outbuildings, stables or sheds with permanent open access, these are warehouses, factories, offices that are locked each night and a hive of activity during the day. Once in, there is often no obvious escape, either because the doors are shut or the activity puts birds off. In many cases they simply cannot find the way out. 

So what to do? It can be distressing not only for the bird, but for the people too. Many spend hours trying to shoo a bird out, only to get stressed as it swoops high up in a warehouse, perching on rafters and lights. The bird seems to just continually avoid the wide open door where the wind whistles through. Then they try ringing for help. But who you gonna call? Well not ghost busters that’s for sure. 


The beauty that is a female sparrowhawk

As licenced bird ringers we are in a unique position, in that we are legally able to use mist nets and other methods to capture wild birds. More than that we have the experience of how to go about it.
So when Lee received a call mid-week to say there was a sparrowhawk trapped in a workshop in Thetford it was time for us to step into action. Amongst cars in various stages of repair, perched high up amongst the dust, the rafters and the strip lighting a female sparrowhawk sat gazing down. She kicked up dust every time she flew, changing perch as she watched the activity below with a bright yellow eye.

With a strategically placed net, utilising an elevated section of the workshop above the offices, it was not long before we had the bird safely in a bird bag and ready for releasing. We took the opportunity to ring the bird, it is not that often that we catch female sparrowhawks as they tend to be bigger than males and do not readily stick in our small mesh nets. With some biometrics taken and a brand new shiny ring, the last thing we did was show the bird to the workers, who for the morning had simply seen the tail end of a brown streaky bird sprinkling dust on them. Many had never have seen such a beautiful bird so close…

Here you get a real sense of the size of the bird

And so to the great relief of bird and workers alike this trapped sparrowhawk spread her wings and took off into the bright Thetford sunshine, no worse for wear from the experience of the last few hours.

Ghostly Gulls

It seemed the spirit of Halloween was lingering, as a spooky, thick fog obscured all but the closest trees and the river. There was no wind and the dangling leaves of the willows trailed in the smooth flowing water like fingertips creating miniature ripples and whirlpools. Out of the white gloom came a brilliant flash of blue as a kingfisher shot down river and up into the lower branches of the willow, watching and waiting. The other birds of the river continue with their morning rituals, although it is already comparatively late in the day for them with the sun having been up for a few hours already. Ducks meander just past the old road bridge on whose worn stone you can still see the scars from tanks. Canada Geese preen themselves or feed on the grassy banks oblivious to the occasional car that appears briefly from the gloom. Overhead the harsh call of Carrion Crows and the cackle of Jackdaws echoes through the fog. Moorhens emerge from the reeds and sedge along the river’s edge with their characteristic bobbing head, circle a few times then disappear again. A family of Mute Swans, the two young still greyish brown, slowly patrol this small stretch of river. From the shrouded trees comes the twittering calls of various tits, Robins and Blackbirds, all heard but not seen.

Black-headed Gull (winter plumage)

Across the dark water stretches a footbridge, the clattering of puppy paws and footsteps its usual fare. But today it has a mist net covering its length, rising high above its barrier. The lure of food brings the ducks, swans and even the Moorhens closer to this bridge, and with them come the Black-headed Gulls. Brilliant white underneath, with silvery grey backs and bright orangey red legs and bill, they bounce effortlessly through the air like ghosts. Their heads are essentially white, with just a smudge of black behind a bright, black eye. Twisting and turning they spy the provisions, dropping down to pick at it from the water’s surface, watching as what is not gobbled by duck, goose or swan floats down river and under the bridge. The gulls flick up and over the bridge and one falls into the trap. The large mesh net is adept at holding the larger, longer winged gull until it is removed by experienced hands. 

And so there it is, in the hand, a small elegant Black-headed Gull. All ready for a metal ring, and in this case a colour ring to add to the project looking at gull movement from the region. We know birds are often moving between the UK and the continent especially Denmark and The Netherlands. But individuals have been found further afield including Senegal and Mauritania. So where will this bird go? Who knows but it will be easier for someone to report it since it has a colour ring which means it can be identified without being re-caught.

Ringed and colour ringed

It does not take long to process the bird. Unlike some of the larger gulls that take a number of years to replace all their juvenile feathers and look adult, Black-headed Gulls are will attain adult plumage when they are just over one year old. So at this time of year, there will either be first-winter birds (so birds hatched this summer) or adult winter birds. And so with that, and its colour ring, the bird is weighed and measured and then released quickly disappearing into the smokey fog.

Red Letter Day

For the last couple days the winds has been coming in from the East, sending birders scurrying to the coast in search of rare and vagrant birds brought over from the continent. Red-flanked blue tail, yellow-browed warblers, Isabelline shrike and Pallas’ warbler all turning up at coastal sites around Norfolk and Suffolk. To me, yes these are exciting birds, some of which I would love to see. But my priorities have changed. And it is not all down to the little Robyn bird that has become the centre of my world over the last 12 weeks. Even before she arrived, once I had become a bird ringer my priorities and focus shifted from birding to bird ringing. The easterly winds may have brought some unusual birds but it also heralded the return of our common winter migrants. Across the dark velvety sky in the early hours of Wednesday morning, with stars still twinkling and only the smallest hint of lightening of the sky signally the coming dawn, came the distinct but thin, almost wistful ‘seep’ call of one of our commonest winter migrants, but also one of the most beautiful. 

In the gathering light, with the reeds and trees at Cranwich rustling quietly in the breeze, we set a series of mist nets. Through the dark comes the deep rumbling roar of Red Deer, hidden by darkness and trees but sending tremors through the early dawn. As the morning draws on the sky is soon filled with hundreds of small, dark thrushes, with that distinct ‘seep’ call. They are Redwing. Circling through the sky now filled with hurrying clouds, moving in flocks from one tree to another and soon dropping down to where our nets stretched through open corridors between the pools, reeds and trees. 

The beautiful Redwing

Up close they are beautiful birds. A bold, creamy stripe above the eye, cuts through the olivey brown feathers of the head. A slightly less pronounced stripe runs underneath the eye. The glossy brown continues down the back and tail, while underneath the pale chest is streaked with dark brown spots. Under the wing is a deep, chestnut-red splash of colour that spills onto the flank and from which the bird gets its name. 

For each bird we look to age it by assessing the quality of the feathers, looking for any changes in colour, any pale fringing and the amount of wear. From this we can tell whether the bird hatched this year, or either the year before or at some point before. Due to the way adult passerines moult after each breeding cycle we have no way of knowing exactly how old the bird is from feathers alone. Only ringing details can do that. Once aged, we measure its wing, record how much fat it has, the condition of its breast muscle, and weigh it. It is then released to join the rest of the flock still hanging round the willows and alders of Cranwich. 


It is a tremendous day, with so many Redwings moving through we inevitably managed to catch a few…. Well 66 to be exact! But that was not all for the day, Goldcrest, Treecreeper, Robin, Chaffinch, Chiff chaff, Wren, Greenfinch, Reed Bunting Long-tailed Tit, Cetti’s Warbler, Kingfisher, Siskin, Lesser Redpoll, Song Thrush, Marsh Tit, Great Tit, Blue Tit and even a Willow Tit (a species that until this year we have not caught on the site since 2009!) added to a the grand total of 195 birds caught and processed on this Red Letter Day for ringing at Cranwich.

Bearded Beauties

Head to many of the larger reed bed sites in Norfolk and Suffolk and you have a good chance of encountering these little birds. In many cases you may not even see them. From the tall, waving reeds their nasal ‘ping’ bounces around like a pinball machine. If you do see one, it is often a small, seemingly brown ball of feathers, trailing a long tail zipping across the tops of the reeds. If you are lucky enough to catch site of one stationary you are confronted with a small, beautifully marked and delightful little reedling that is at home gripping on to a vertical reed stem. The brown is revealed as a tawny, orangey brown and there are stripes of creamy white and black on the wings, a long rufous brown tail trailing behind the stocky little body. The males have a silvery blue grey head, small bright yellow bill, brilliant orange eye and stunning black moustaches... so I guess Moustached Tit did not have quite the same ring as Bearded Tit. The females, while lacking the silvery grey head and moustache, are still just as delightful but in a more subtle way. 

So yes, while throughout the year you may be lucky enough to hear or even see these little, restless birds in the larger reed beds of the region. But at our comparatively little reed bed at Cranwich? Well as a matter of fact yes! In the past few years the characteristic pinging of a pair of Bearded Tit has been heard in the reeds fringing the margins of our pools. Clearly while many Bearded Tits remain in their large reed beds year round, some disperse during the winter. The calls at Cranwich have only been heard in the autumn and spring, there is no sign of them breeding… yet.

So with the final session of the season underway it is with some excitement that through the still, cool autumnal early morning we hear that pinball ping. With the sun beginning to warm the cool air it was with delighted surprise that from the bird bag I took out a stunning, male Bearded Tit. The first time I had held this gorgeous bird in my hand. The next net round brought the added pleasure of catching a female. 

A stunning male Bearded Tit

No less beautiful, the female Bearded Tit

So here we are, on our little reed bed site with a pristine pair of Bearded Tits. Both adult and young of the year replace all their feathers at the end of summer, so there is no way of telling whether these were young dispersing or adults moving away from the breeding sites. Where did they come from? In all likelihood to answer is nearby Lakenheath but may be somewhere further afield? But where do they go to? Remain at Cranwich for the winter or carry on to some other destination? And where will they return to breed? One day could the answer to that be Cranwich? Ringing this pair will hopefully help to start providing some answers…

Don't count your robins before they've hatched

It may be one of the most iconic and recognisable garden birds in Britain. With its long, spindly legs, hopping across lawns, pecking at seed and insects on the ground, perching on wall, fence, branch. That beautiful orangey red breast and olive brown back, big dark eyes. Everyone knows the robin. From bossing your feeders (for such a delicate looking bird it is actually the one that tends to rule the roost at the feeder in winter) to it’s confident, melodious song that is heard often well before sunrise and throughout the year. This cheeky bird adorns our Christmas cards as well as often being so confiding they will learn to take meal worms and sunflower hearts from the very tips of ones fingers. It is hard to believe they are disdained in other European countries (which I was shocked to hear from a friend who sent a Christmas card with a robin on to a friend in Denmark!). On these fair shores the robin remains a firm favourite even if it will defend its territory to the death. 

The beautiful robin

For me I love ringing and handling robins. Catching them and learning how to age them (sometimes not as straight forward as they first appear). I also love finding their nests. For a bird that is so ubiquitous their nests can sometimes be quite hard to find. Hidden in all sorts of places on trees, on banks, in a wall or hedgerow, or even more unusual places like a horses muzzle hanging from the back of a door on a shelf in a workshop. The small, delicate nest is made from moss and dead leaves, lined with hair and wool, sometimes so perfectly blending in with the rest of the tree trunk or hedge row. Here usually four or five small eggs ranging from off white with brown speckling to a reddish brown all over, are carefully laid and incubated. The naked blind chicks, with just a bit of almost fuzzy down hatch after a couple of weeks and barely fill the bottom of the nest, squirming over each other, huddling to keep warm as mum and dad begin the furious job of finding enough food to feed them all. The instinctive reaction to lift their heads, mouths wide open showing a bright yellow mouth (a perfect target for a parent in a rush) means that when one checks a nest this is often the heart melting sight they are greeted with. 

Within a couple more weeks they are huge, pretty much full size and filling the nest to bulging point. A careful peer in will now reveal bright eyes, alert and looking back. Time to be really careful. Very very soon the next visit reveals an empty nest, trodden down with poop around it revealing that the chicks have left. It lucky you may catch a glimpse of the brown speckled young in the surrounding trees still scrounging a couple of meals from mum and dad. Soon they will be fully independent and shortly begin a partial moult that will, for all intents and purposes, make them look like an adult. Only in the hand will an experienced ringer be able to tell if a bird hatched that year or the previous. And so the cycle will begin again, where possible birds will spread out and maintain a territory for the winter before looking to pair up and breed themselves the following year. 

One of the more unusual locations of a robin nest

Each year it is my pleasure and honour to find a couple of robin nests, to monitor them where possible from building to egg laying, hatching to fledging. Always they have been nests with four or five eggs. This year though, in the crook of a small stump of a tree, overhung with ivy, I found a nest that once more had five eggs. However a return visit revealed a surprise. Not five, but nine eggs sitting in the bottom of this perfect little nest! Never in all my years of nesting (which are not that many to be honest) have I seen a robin nest with nine eggs, but more than that neither have many of the more experienced nesters I work with! Whether this is just a particularly fecund female, or whether another female has come along and dumped her eggs into the nest to save making her own, I will never know. But the female was good. 

Nine eggs! (last one tucked out of sight)

A couple of visits revealed her sitting tight, and I would leave her be, others she would not be there but I could hear her scolding me in the surrounding leafy foliage, ticking above the rush of traffic beyond. I was unsure how many would hatch but the next visit revealed another pleasant surprise. Eight tiny, squirming chicks crammed in. But how many would survive? How many would mum and dad be able to feed. Only time would tell, but a few days later and all eight were still alive and growing, ready to be ringed. Each now marked with a unique metal ring. Whoever or however many do fledge and survive, if they are ever found again by another ringer or a member of the public I will be able to tell straight away they came from my little miracle nest. 

Eight chicks in  a bag ready for ringing

It is worth saying here both Lee and I are qualified and experienced nest recorders and ringers. These chicks were safe during the whole process, which was quick and completed efficiently.
