Lapwings

 A light spring mist lies across the lush green grazing marshes of Essex. The tiny herd of cattle stare me down with curiosity as I begin walking across the open field, the morning dew soaking off the grass onto my trousers. A cuckoo calls distantly, one of the closing headliners of the fading dawn chorus. I am looking for something else.  I am alerted to the presence of the bird I am looking for by its alarm call. It lifts into the air on broad, square wings, black and white, climbing quickly and turning sharply, and bears down on me, whistling its curious electronic whistle. The adult Lapwing makes several passes over me, close enough to let me know I am not wanted in its territory, but never close enough that I feel in danger of being pecked.  Its underside is bright white, its wingtips black, its eyes fixed on the potential danger, and its call almost otherworldly, to my mind recalling science fiction ray-guns, or Clangers, perhaps.  To others it may be the archetypal sound of the British countryside in May and early June. The reason for the adult Lapwing not wanting me there, and its reluctance to leave, is close by, at the muddy margin of a small pond, once a creek now cut off from the tidal river, pecking around in the mud. A tiny, awkward, fluffy chick, with a crown of mottled brown and a white collar, it’s one of the few chicks in whose downy plumage one can see the markings of the adult. A tiny, precarious little life, prodding around in one of the few remaining sections of its habitat in the county. The landowners here are rightly proud of their breeding Lapwings, and of the habitat they live in, and go to considerable lengths to protect these birds.

Lapwing, Speyside, Scotland, May 2023

Breeding Lapwings are not a typical part of the countryside in South East England. They have declined significantly since the 1950s, with the advent of intensive farming, and the loss of grazing marshes. They tend to do well on nature reserves managed for them, with water levels and grazing tightly controlled, and predators controlled or else excluded by metres and metres of electric fencing. Where I am now, a long way from Essex, North of the Border and then some, in the lush, green glens of Strathspey, Lapwings, and other farmland waders, are still a feature of the wider landscape, where lower intensity farming methods persist, though conservation organisations build links with farmers to promote their conservation. Elsewhere, small numbers of dedicated farmers and landowners are supporting the Lapwing’s return to the wider countryside, but they face an uphill struggle. They require very specific management, with grass short enough to allow a nesting adult a line of sight, for early identification of ground predators. They are highly vulnerable to predators, especially where shrinking colonies no longer allow a coordinated mobbing response.  They prefer shallow, standing fresh water in their nesting fields to persist into June and July to allow the chicks to feed, and cannot tolerate complete dessication of the soil, a challenge in times of changing climate.

Lapwing, Speyside, May 2023

To many birders Lapwings are very familiar, particularly from their wintering aggregations, their big flocks wheeling in the sky, turning from green-black to brilliant white as the birds bank and turn to evade a passing Peregrine or a Marsh Harrier. They are one of winter’s great spectacles. I recall immense flocks wheeling skyward against a backdrop of distant skyscrapers and wind turbines at Rainham Marshes on the edge of London many times.  One winter flock might comprise locally bred individuals, alongside birds from the near continent and beyond. A study from the Netherlands found that Dutch birds travelled to England, and to North Africa for the winter before returning to the same Dutch fields in Spring. They are individually faithful, as far as we can tell, to their wintering sites, but sometimes snowfall or other severe weather can displace them, and they need to undertake movements South and West to find food. They are largely short-range migrants.  Sometimes their flocks can be seen overflying even urban areas as they search desperately for a gap in the snow.

Lapwing, Lincolnshire, 2021

They are one of those birds which were they scarce or rare we would look at in absolute wonder. They’re a member of the Plover family, perhaps feral pigeon sized, topped with a smart black crest, over a friendly looking face in black and white, with big dark eyes and a short bill. Their undersides are white, and their back a palette of iridescence, mostly green but with notes of red and purple depending how they catch the light. Back in 2011 and somewhat blasé about Lapwings, given the large wintering numbers at some of my local patches, I was a volunteer at the Gialova Lagoon in Greece, where, one bright September day, in the heat, I encountered a Lapwing on the edge of some scrubland, and told my supervisor, she went running off after it, and came back cock a hoop to have found such a beautiful and unfamiliar bird.

Lapwings, RSPB Rainham Marshes, Greater London, 2011

But again, with such a decline in their breeding population, their wheeling summer displays and territory holding electronic sounding calls in an English, or even a Scottish summer, may become confined to specially managed reserves, or worse, a thing of the past. And, while managing for them is not easy, and can be costly, and thankless, it would be a great sadness not to see and hear that. And some people are investing the resources and energy required for Lapwings to return to the Essex countryside. And indeed, later in the season, when I returned to that site, the chicks had become two flighted juveniles, short crested, scaly backed versions of their parents, and it was great to see them making their way across the sea wall, to the Saltmarsh, to feed up on the wealth of shoreline invertebrates, before moving on, to wintering grounds near or far.

Wanderings in the Strangest Summer: A trip South, Part 2. 20th-21st July 2020

 A walk from Stone

Mum and Dad and I went up to Stone, on the South side of the River Blackwater, up in the wilds of Essex. I spent a few hours strolling the sea wall, strolling and wildlife spotting in the glorious sunshine, as my Dad played with boats.  Birds were surprisingly few and far between, with, in what must be a first for a walk by the River Blackwater,  no waders spotted, though Common Terns flew by with characteristic grace. However there was a veritable feast of butterflies. Mumsie spotted a Marbled White, and as I walked I counted many of these big Satyrids, and a pair danced among the parched grass.  Their dance, presumably a courtship display, was rudely but accidentally interrupted by a Small White, causing one of the Marbled Whites to abandon the dance, and the other, if one can imagine a butterfly angry, chased the intruder furiously for 50 metres or more along the sea wall, until they were out of sight.

One of the 101+, female Gatekeeper at Stone. 

Butterfly highlight was a pair of Clouded Yellows, which flew up and down the sea wall at speed, full of the sun's energy, and then ascended, twisting and turning around each other, into the blue heavens. Clouded Yellows are a scarce, accidental migrant from continental Europe, some years irrupting into Southern England across the channel. Sadly they are continuously brooded, and seem unable to survive a British winter, and little correlation is seen between their numbers one year to the next.

View of the Blackwater at Stone

A curious, large black bumblebee was not identified, and I think subsequent investigation led us to the conclusion it was probably a melanistic example of one of the Cuckoo bee species.

Melanistic form Cuckoo bee spp. 

A single small copper, and a number of little orange Small Skippers flew, but Gatekeepers were by far the commonest butterfly, indeed I maxed out the counter on the iRecord butterfly app, which settled, curiously, on '101+.' A beautiful Great Crested Grebe fished on the shimmering water, and Dad enjoyed the song of a Wren from one of the sailing club chalets.

Canvey Wick, 21st July 2020

Mumsie and I found our intended destination, the excellent RSPB reserve at West Canvey, was still closed as a result of the coronavirus, so we headed over to the Buglife/Land Trust/RSPB reserve at Canvey Wick, a former industrial site, its concrete now home to some rare and unique invertebrates, including Shrill Carder Bees, one of the country's rarest bees, and Brown Banded Carder Bees.

The summer sun was high, and bright, and the air was calm, the weather glorious. 
 
Sadly, during lockdown the dog walkers had been doing their worst, and the path up from the car park was rather unpleasant, but entering the reserve 'proper' we found a riot of floral colour, from tiny alpines, to large and unfamiliar blooms, scarcities and garden escapes leaf by petal, no doubt. They rather made me wish I was I was a better botanist.

Note absence of figure 8 on hidwing and additional spot on forewing. Common Blue at Canvey Wick.

From a high wooden platform stretching over the Thames, we saw the unmistakable shape of a Whimbrel, probably a returning migrant, probing about in the mud with sharply downcurved bill, while Godwits flocked in the distance. A Little Egret flew out from under us, brilliant white in the sunshine. There were plenty of Carder Bees of various descriptions about, and beautiful little solitary bees. Whitethroats sang, and we saw many fledglings of this charming warbler. Mumsie found a Wall Butterfly, and a stunning Holly Blue, which invited photography.

Wanderings in the Strangest Summer- A Trip South, 17th-21st July 2020, Part 1.

Stretching the definition of 'on the way' a little, I stopped off at Lakenheath Fen in Suffolk on my way to Upminster, from Wirksworth. Lakenheath Fen sits close to the USAF base at RAF Lakenheath, in the Brecks close to the Norfolk/Suffolk/Cambridgeshire tri-point. A new wetland, a masterpiece of habitat creation, its reedbeds and open water were once carrot fields, and they sit alongside poplar plantations, where Golden Oriole once bred, indeed, they were among the last sites used by this species in the country.

Peacock Butterfly at Lakenheath Fen

I was welcomed by friendly RSPB volunteers, who informed me the site was now fully open, the reserve open access until Dusk, and served me a welcome coffee, before I headed up beside the river Great Ouse, looking across its Lapwing and Godwit infested washlands. The thistles presented a wonderful display of Peacock and Red Admiral butterflies, so many of these magnificent but familiar big nymphalids on the wing. I made my way to the Joist Fen viewpoint, which was surprisingly busy, with a lot of people about including a man with a big camera and a sound lure, a device playing Bearded Tit contact calls. These are highly frowned upon, and thought to disrupt birds breeding behaviour, or at least distract them from foraging. After some dirty looks from the assembled he went on his way, and, satisfyingly, no sooner had he done so, than the Bearded Tits arrived, affording us brief but clear views of these charming, mustachioed denizens of the reedbeds, busy, little brown birds with reed-brown bodies, long tails, and in the males, blue-grey heads and elegant black mustaches.

Red Admiral Butterflies and Red Soldier Beetles at Lakenheath Fen.

The Beardies did not hang around, and bird-wise, the viewpoint was quiet, with no cranes to be seen, these being the other star bird associated with Lakenheath, so, making my walk a circuit, I walked back along track and boardwalk, beside open water, and yet more butterflies including a gorgeous Brimstone, toward the visitor centre.

After this I took another, shorter circuit, up to the New Fen Viewpoint, where a Bittern flew by, and Scarce Chaser dragonflies, males tarnished cobalt blue, staining black according to their age, females a shade of gold in the sunshine, alighted on the benches. and Common Lizards sunned themselves on the boardwalk. There were bright scarlet Ruddy Darters here too. Several Marsh Harriers flew lazily above the nodding reeds, these still uncommon raptors now almost ubiquitous in the Anglian fens, and deep in the reeds, Reed and Sedge Warblers, the rave DJs of the wetlands, sang their ever changing, but distinctive, rhythmic song.

Male (top) and Female (bottom) Scarce Chaser at Lakenheath Fen.

I looped around the family trail, taking in the less explored part of the reserve, the air alive with the song of whitethroat, and more spectacular nyphalidae on the wing. Then I headed on my way, back across the country to the M11, the songs of Acrocephalus warblers still ringing in my ears.

Cranham Marsh, Essex, 19th July 2020

Cranham Marsh is a small Essex Wildlife Trust reserve, a stones throw from where I grew up, indeed, a short bike ride for the younger me, and a place I loved to visit through my teens and 20s. Indeed, I credit walks at Cranham Marsh with reigniting my fascination with wildlife after a few challenging years I had when I was at University, first time round. It's not famous like Lakenheath Fen, but it is important in my personal headcanon of nature reserves. It has been well used by people, barely sitting outside of the leafy suburb of Upminster, but is by and large treated with the respect it deserves by many people, and I hope continues to inspire suburban people to get out and enjoy wildlife.

Mumsie's Brown Argus. 

It was another gloriously sunny day, and there were abundant butterflies on the Hemp Agrimony and Centaurea and the thistles, including a smart Brown Argus (Aricia aegestis) which Mumsie spotted, and a number of bright Common Blues and Holly Blues, all tiny lycaenid jewels in the long grass and among the flowers.

Peacock on Hemp Agrimony at Cranham Marsh

Jays, and Rose Ringed Parakeets, now ubiquitous around greater London, were calling, and a gorgeous Field Vole, Britain's most numerous mammal, but seldom seen, a small dark ball of fur, ran across the path. It was rather a trip down memory lane. 

Cranham Marsh nominally hosts wet grassland habitat, perhaps better described as seasonally wet, seldom holding much water into the high summer.  In this spell of hot weather we were enjoying, parts of the reserve seemed parched and dry.  The site is said to have suffered from the building of the M25, but it still hosts remarkable wildlife. 

I visited again on the 21st, just as a place to enjoy a cold beer and a bench with an old friend in the scorching sunshine, and on that visit, I managed to snap an unexpectedly interesting photo of bees, on the thistles.

RSPB Bowers' Marsh, Essex

I took half a damp day, the sun gone, to walk around this damp piece of land, an RSPB reserve sandwiched between the Essex town of Pitsea and a landfill site, to walk a circuit, and tick more bird species than I did at their fenland flagship, in drizzling rain. 

There were a few runners and dog walkers taking their permitted exercise, and to my surprise, a few motorcycle scramblers about. Under the partial reopening permitted, I caught the reserve just before it was closed again due to antisocial behaviour.

Record Image of Black Necked Grebe at Bower's Marsh. 

The birds were the stars of the day, and there were many, Avocets had fledglings on the islands in the scrape. A single Black Necked Grebe, an attractive, relatively scarce species, with Macaroni Pengion ear tufts, a distinct, sharply sloping forehead, a ruby red eye set in a black head and neck, and rich chestnut brown flanks while resplendent in breeding finery, hung out on the water with a small band of Pochards, diving frequently. In the reeds at New Marsh Viewpoint, I again encountered Bearded tits, for the second time in three days! A smart male, and two youngsters made their way between the reeds.  Common and Green Sandpipers were on a black and rubbish-strewn patch of water on the other side of the fence separating me from the landfill site. A Marsh Harrier made occasional flybys, putting all the waders to flight.

Record Image of Bearded Tit

Another highlight was the Yellow Wagtails. Summer migrants, this flock included a couple of dapper yellow adults, bright, flying dandelions, and a couple of muddy yellow and olive youngsters.  Yellow Wagtails are a widely distributed and variable species, with geographically distinct races, though these were true yellow wagtails, the near-endemic British subspecies, Motacilla flava flavissima, and had probably bred locally, though in a few months they would begin their long autumn migration to sub-Saharan Africa.  

Despite the grey, there was a Marbled White butterfly on the wing too, big and blousy, blown about by the breeze.

Warley Place, Brentwood, Essex, 19th July 2020


I spent a couple of hours with the family bimbling around one of Mumsie's favourite spots, Warley Place near Brentwood, a fascinating reserve near Brentwood. The reserve's origins are interesting, they form the grounds of a long demolished stately home, once occupied by Ellen Wilmott, keen gardener and plant hunter. Many of the exotic plants she grew in her gardens still survive, though under a canopy of mature trees, the house, unoccupied since before the second world war, was demolished in the 1960s, and the gardens left to fall to ruin, though elements of them have since been partially restored. The historic structures which still stand, parts of a conservatory and a coach house, are maintained in an as-is condition, and the Edwardian glory of the gardens can easily be imagined.

Rutpela maculata on cultivated Rose. 

Two hides stand on the site, overlooking small bodies of water, one a garden pond, the other the irrigation system beneath a long demolished hot house, each with bird feeders outside, attended by Great Spotted Woodpeckers and a few common passerines. Ginkgo biloba grows alongside cultivated roses and bamboo, relics from Ellen Wilmott's day, alongside self seeded secondary woodland.

Among the curious creatures we found was a beautiful longhorn beetle,which Dad spotted atop a rose flower. We identified as Rutpela maculata.

Wanderings in the Strangest Summer- A retrospective.

 2nd June 2020

I parked the car in Elton, a small village just off the road to Bakewell, and took a wander along the still quiet country roads to Gratton Dale, a dry, narrow dale, host to a lot of scrub as well as wildflower rich, limestone grassy banks. There was a huge abundance of butterflies, Common Blues chasing off anything in sight. The Common Blues combined with the activity brought on by warm conditions made photographing butterflies very challenging. Among the butterflies chased off by the territorial blues was a scruffy Green Hairstreak, a species coming to the end of its season. There were plenty of very fresh Brown Argus on the wing too, possibly the univoltine (single brooded) race which occurs round here. A Tawny Owl hooted in the daytime, which seemed unusual. The blackbirds were going crazy, mobbing something unseen. A pair of Redstarts were provisioning their young.

Brown Argus

Common Blue

A couple of years ago Gratton Dale had hosted hundreds of Dark Green Fritillaries, I had visited them in late June, an abundance of big orange butterflies, but this time I only encountered a single individual. Perhaps their numbers will swell towards the summer Solstice. There were still a few early season species about, in Brimstone and Orange Tip as well as Green Hairstreak. The beetle Oedemira nobilis was seen in good numbers in all their green jewel brilliance, both sexes, thick-thighed male and female, feasting on the large daisies. Abundant Large Skipper butterflies were my first of the year of this common species.

Long Dale was quieter, and lacked the wild kaleidoscope of butterflies, though a Skylark sang overhead. A small copper was pretty but camera shy, and there were plenty of Small Heaths. Long Dale is a National Nature Reserve and kept close grazed, genrally regarded as very well managed, buit I felt it perhaps a little overgrazed, and it lacked the diversity of habitat and the lush verdance of Gratton Dale.  Day flying moths were about, including a Wood Tiger, an arctid with beautiful cream and brown forewings and yellow dappled hindwings, and Forester moths, I'd not like to guess a species, fat and metallic green, were abundant.

Small Heath

Wood Tiger

I climbed the footpath North out of Long Dale over the farmland, and a pair of Linnet watched me attentively as I passed, from a perch atop the Gorse. I avoided a field full of cattle and took in the views. A narrow path among the white Cow Parsley led me down to a road, which I crossed, entering a treecreeper infested patch of woodland. This led me along a stone path to the infant River Bradford. I elected not to try to walk Bradford Dale too, on grounds of time, and took the footpath back toward Gratton village and Elton. Near Gratton I saw a stunning Brown Hare in the grass, and in the grounds of a dairy, numerous Small Tortoiseshells defended a patch of nettles.

Large Skipper

Gratton Village was gloriously wildlife rich, surprisingly so, with an attractive pair of reed buntings, apparently breeding beside a small stream. Chirping House Sparrows were around the houses, and House Martins nested under the eaves. A beautiful Wall butterfly was an unexpected pleasure to see in this pretty stream side hamlet.

I made my way across more fields back into Elton, to head home, having enjoyed a beautiful, butterfly rich stroll in the glorious June weather.

Lockdown Walks, a Retrospective.

 6th May 2020

I took a brief afternoon stroll in Stoney Wood, the little local greenspace in a disused quarry I have visited many times, for an informal bird and butterfly survey. Here I witnessed predation, nature, in all its shocking glory. 

The prey, fast, agile, and undeniably beautifully marked, was flying at treetop height, and clearly very aware of the danger it was in, jinked and turned aerobatically, in a desperate attempt to escape the snapping mandibles. The predator, faster, but not as agile, hung briefly in mid air, before locking on again with its sharp vision, darted and snapped again, and missed again. They prey had almost reached cover, but changed direction, and this loss of speed afforded the predator another chance, and this time, with an audible snap, the sharp bill found its mark. The Spotted Flycatcher returned to its perch in the scrub with the Peacock Butterfly flapping desperately in its tight grip. The bird struck the insect against a branch several times, until the manic struggling ceased. Then it shook its head violently, and the four jewelled wings of the butterfly fluttered to the ground like falling leaves, and the bird devoured the body, a small, sad morsel but of course a substantial meal to the tiny bird. 

Peacock Butterfly. Not the one in this story but one in Cambridgeshire in August.

This horror aside, the weather was still glorious and there were plenty of butterflies on the wing, including several Dingy Skipper, and Robins, Whitethroats and Willow Warblers, insect killers all, sang melodiously to the summer sky.

Orange Tip Butterfly near Kirk Ireton.

8th May 2020

 Wirksworth to Carsington via Kirk Ireton

I strolled along footpaths from Summer Lane, where the housing on the Southern fringe of Wirksworth gives way to farmland. I crossed the open fields and climbed up to half moon lane, which was quiet and offered beautiful views over the Ecclesbourne Valley. The roadside vegetation was well grown and butterfly infested. A Sparrowhawk soared as racing pigeons took their daily exercise from someone's loft. Swallows and Martins wheeled above a farmyard. I arrived in Kirk Ireton, and was surprised to find the human population out and about, celebrating VE day in the streets, a dose of normality, but still a surprise. 

After a couple of wrong turns, I think I had been aiming for the Trig Point called The Mountain, I found myself unexpectedly stood beside Carsington Water, not far from the Millfields car park. A beautiful Garden Warbler sang on the Hawthorn, and the Black Headed Gull colony was typically noisy. A few Lapwings and a single Redshank waded in the shallows. A pair of feral Barnacle Geese were on the gull colony island and one appeared to be incubating.  Long Tailed Tits foraged in the shrubs, gathing beakfulls of insects for their waiting chicks.

Long Tailed Tit at Carsington Water. 

I returned via Kirk Ireton once again, through sunny fields full of butterflies and horses, and filled my empty water bottle with takeaway beers from the pub there. I sat in a field on the way back and raised a glass to the men and women of 1945.

Garden Warbler at Carsington Water

Returning in near darkness I saw hares close to where the footpath crosses the Alderwasley Hall School site. The vegetation here was a sad sight, the farmer appeared to have sprayed herbicide on nearly everything, and wildflowers and nettles alike drooped forlornly. I crossed the Ecclesbourne Brook and returned to Wirksworth through Miller's Green. A pond, signposted as a fishery, beside the road reminded me how I was still discovering this town, I had not known it existed.

Dartford Warblers at Arne

Dartford Warblers

Dartford Warblers (Sylvia undata) are among the scarcest and most enigmatic passerines to grace these islands, and surely among the most charming. When vast tracts of heathland covered much of Southern England, the species was not uncommon, and it is named for Dartford Heath in North Kent, from which it has been absent for decades.  Perhaps more at home in Mediterranean Europe, it is on the edge of its range in Great Britain. With the increasing development and fragmentation of this habitat, sitting as it does in desirable Surrey and Dorset, it underwent decades of decline.  It is also said to be particularly vulnerable to predation by domestic cats, which can exclude it from small scraps of habitat saved from housing developments. An exclusive insectivore, and largely sedentary species, its greatest enemy is the British winter, persistent snow can wipe a colony out, and a cold winter in the early 1960s nearly did for the British population entirely, just a few pairs appearing after the snow finally melted.  However, amid great conservation effort and with possibly a small helping hand from climate change, the species is beginning to recover. 

Dartford Warbler at Arne.

There are a few places where these birds can reliably be found. Arne, and surrounding fragments of heath, and Chobham Common in Surrey, where I first met the species, host good numbers year round. They are vulnerable to disturbance, and responsible birders do not go tramping through the heather at any time of year. Occasionally individuals turn up on the coast in Southern England, undertaking short movements to avoid the very worst of the weather.

A view from Arne.

It was at the RSPB’s magnificent pristine heathland reserve at Arne, near Wareham in Dorset, that I had my most recent, and most magical encounter with these gorgeous little passerines. A solo expedition to one of my favourite corners of the country in the hope of catching up with Nightjar (I did, but not enough to blog about), I camped near this magnificent spot, a large tract of Dorset coastal heath on Poole Harbour overlooking Brownsea Island, managed impeccably for conservation, and took a long stroll among its heathland rides.  Arne was abuzz with dragonflies and butterflies and hoverflies, and 90 common spotted orchids grew along the bank of one small pond which must have hosted half a dozen different Odonata, including an iridescent Downy Emerald and a striking pair of Emperors including an Ovipositing female. It was becoming a good day.

 It was the song of the Dartford Warbler that first caught my attention. Imagine the song of a Whitethroat (Sylvia communis), and consider the qualities and notes which ensure the song is often described as “scratchy.”   Now distil those scratchy qualities, concentrate that Sylvia scratchiness,  andyou will begin to imagine the song of the male Dartford Warbler.  The male caught my eye first too, a small, dark coloured bird, with a longish tail, proportions somewhere between a Cetti’s Warbler and a Long Tailed Tit. He alighted briefly at the top of the heather, sang a few notes, and dropped back into the thick tangle of waist high vegetation.  He reappeared and my eyes strained to see his features in the sun glare, his dark blue-grey back and wings contrasting little with his dark pink-red underparts, and he had an air of cultivated scruffiness.  Rooting in the gorse he popped up briefly with a beak full of spiders, before dropping down to stuff his spiders into the expectant mouth of a scruffy fledgling, brown and distinctly smaller than the adult, which had emerged from the vegetation.   The fledglings and the female never left the thick heather and gorse, appearing to my eye only briefly before returning to the shelter of the thick heather canopy, but the male returned to his commanding lookout and sang, re-stating his claim to this his fragment of the coastal heath, the precious resource upon which his family depend.  Perhaps by remaining in this prominent position he also provided a distraction display focussing the attention of birders, and any would-be predators, on him, allowing the more vulnerable youngsters to slip away.

It was a magical moment with these scruffy, charismatic little survivors, and conservation icons of the lowland heath.  It was heartening to know that, with many small birds finding their breeding cycles disrupted by the late snow this spring, at least some of this most cold-sensitive warblers had successfully fledged broods. This family appeared to be doing well.
