Great White over Headington

For a district that is 67 miles from the nearest sea, it seems strange that Headington is associated with sharks. But Bill Heine’s fabulous fiberglass shark, which protrudes 25 feet above the roof of the house he owned in New High Street, is probably the most famous thing about Headington. It also looks pretty good at night too, here pictured with Comet Neowise in the summer of 2020:

I had my own Great White experience in Headington yesterday morning. It was a routine Saturday morning dawn visit to Warneford Meadow and the Lye Valley. Perhaps early spring, if I really squinted hard enough, but really it was late winter. March 5th is slightly too early for the mass of waterbird migration that should kick off from mid-month and will probably pass overhead elsewhere, but as with all local patch birding, you just never know. So I keep going, just in case. A singing Nuthatch and drumming Great Spotted Woodpecker were positive signs many bird species were entering their breeding cycles. Displaying Greenfinches were obvious too, and Chaffinches had recently started singing.

I watch the skies constantly, as nervous as Vitalstatistix, who lived in fear of them falling on his head. My anxiety was not over the impending collapse of the atmosphere, but of missing a migrating bird flying over. Or worse: of only seeing it when it was already too distant to identify. The vast majority of my scans of the sky reveal either nothing or just Woodpigeons. But if you do something enough, eventually something will happen. Or at least, that is what I tell myself.

At 7:23am, I notice a shape in the sky. High above the Churchill Hospital, flying away and slightly east, it has deeply bowed wings and is quite large. I furrow my brow and raise my binoculars, whilst the words “Grey Heron?” begin to form in my mind. The data from my eyes immediately answer this question in the negative – the bird is pure white, above and below. “F**k, it’s an egret” I mutter, whilst quickly swinging my camera around to capture some pictures. Whilst the motor part of my brain works away on the logistics of getting some pictures of a distant white bird flying away from me against a white sky, the inquisitive part of my brain is still wrestling with the identity of this bird, from what I can see through the viewfinder, whilst I take pictures. “Looks big, very deep wingbeats – got to be a Great White?!” I ask myself, without really taking on the meaning of this.

By now, the bird is distant. My camera is not going to help me much more. I put the camera back on my shoulder and go back to a binocular view. The bird is struggling a bit with the stronger gusts of wind and drops down slightly in front of Shotover Hill, before rising again and continuing its journey east. A local Red Kite provides a nice point of comparison as they pass near each other, both birds appearing a similar size in flight.

Finally, I can hardly see the egret anymore, so I turn and review the pictures on the back of my camera. It IS a Great White Egret! The long, dark legs, trailing behind the body are just visible, as are the deeply bowed wing on downbeats:

You can just about make out the yellow bill here and check out the length of those wings:

Wow, what a start to spring 2022, or what an end to winter 2021-22! Either way, this is an amazing record of Great White Egret over Headington, Oxford, and a great incentive to continue dedicated coverage with spring migration just around the corner. What else might fly over before the sky falls on my head?

Tree Pipit on the patch!

Recording the first Tree Pipit for the Lye Valley area in August 2020 was a special moment. Not least as I put in a fair few hours in the autumn of 2019 without success. This year I had failed to see or hear any Tree Pipits in the last week of August, so when a loud “tzeep” call rang out from the sky on 4th September, I was pleased to record Tree Pipit for the second successive year. That Tree Pipit flew south over the golf course, I heard it call three times as it continued its migration across the county:

For most of today’s patch visit, things had not looked particularly productive. There was little evidence of many new migrants in, a juvenile Ring-necked Parakeet practicing flying low over the golf course greens was the slightly surreal highlight.

As I crossed through Churchill Meadow, right behind the hospital, I flushed a bird from the main track. It was immediately interesting. It flew fast, low and silently to the back of the meadow, but I got enough on it to feel confident that the bird was a pipit. There is virtually no overlap in existing records of when Meadow Pipit and Tree Pipits appear over the Lye Valley, but both could be potentially recorded in early September.

I went back into the meadow and walked through it twice without seeing the bird again. As I returned along the track, once again the pipit rose up, this time flying to a small patch of silver birches on the edge of the meadow. Here I could just glimpse it through the foliage:

I could make out the fine steaks on the flanks and then it began pumping its tail up and down: it was a Tree Pipit! Finally, it turned towards me for a moment, before flying back to the far edge of the meadow:

An unexpectedly brilliant view of a Tree Pipit! I suspect that Tree Pipits pass through the Lye Valley in tiny numbers every autumn, it is just a question of whether anyone is out there to see or hear them. The next target: a nice spring record of this species?

The Lye Valley & Warneford Meadow: Spring 2021

This is a summary of the birds (and some other wildlife) recorded in the Lye Valley and Warneford Meadow area between 20th March and 20th May 2021. There was a brief warm spell in late March, just before Easter, which saw the arrival of a few summer migrants. Then temperatures fell away, resulting in weeks of cold weather, including a remarkable mid-April snowfall. Nationally, spring 2021 was very cold and then very wet! April 2021 had the highest number of days with air-frost ever and was the third coldest on record. May 2021 looks like being the wettest on record. Neither of these factors are beneficial to migrant or breeding birds.

In this 61 day period, there were a combined total of 89 visits recorded on eBird to the Lye Valley and Warneford Meadow area. 59 species were recorded in March; 61 in April and 53 in May. By 20th May, 73 species in total had been recorded this year. 40 or more species were recorded on four days: 20th March; 9th April; 17th April and 1st May.

Sub-zero mornings became a routine, with dawn visits beginning by crunching through heavy frost, well into May:

Female Green Woodpecker in the frost.

In the freezing temperatures, some bird species would sit facing the rising sun to gather what warmth they could:

Male Sparrowhawk

Later in the spring, the local pair of Sparrowhawks would begin displaying:

Early spring sees waterbirds on the move and occasionally such birds would pass over the Lye Valley:

Greylag Geese
Barnacle Geese

However, most waterbird migration is nocturnal. Isaac West and I spent a few nights in late March listening and recording nocturnal migrants. See this post for details of a spectacular night, on 23rd March, when we heard migrating Common Scoter, Coot and Wigeon, as well as recording the first Barn Owl for the area.

Back in daylight hours, despite the temperatures, nesting behaviour could still be seen:

Red Kite with nesting material.
Singing male Grey Wagtail.
Singing Chiffchaff.

The rarity highlight of the spring occurred on 10th April when a Ring Ouzel flew over myself and Phil Barnett in Warneford Meadow. A few hours later a male Ring Ouzel was located in Marston Meadows in Oxford, perhaps the same bird? Ben Sheldon has been regularly visiting Aston’s Eyot, by the River Thames just off the Iffley Road, some one mile to the west of the Lye Valley area. Eight days after the Ring Ouzel flyover, I received the sort of text message that sends the inland local patch birder into cardiac arrest:

We can forgive Ben his typo. I know what seeing Bar-tailed Godwit migrating over your patch does to your adrenaline levels. It is incredible that Bar-tailed Godwit have been recorded flying over Oxford city in two successive years. I ran up to the nearest point with a view of the sky and scanned desperately, but to no avail. Ben followed this with reports of Marsh Harrier and singing Redshank overhead, neither of which materialised over the Lye Valley either!

The cold weather took a dramtic turn on 12th April with a heavy fall of snow, documented here:

Fortunately, despite several centimeters of snow, it had melted by lunchtime. The surreal sight and sound of a Willow Warbler singing in the snow was remarkable:

Once the snow was gone, spring behaviour returned. I have noticed Jays flocking together in large groups in April in a number of years now:

There were also drumming woodpeckers and displaying Treecreepers, whilst Siskins and Lesser Redpolls remained into late-April this year, much later than usual:

Treecreeper

This spring was a good month for falcons, with three records of Peregrine and two records of Hobby, as well as the local breeding pair of Kestrels.

Peregrine
Hobby

By mid-April first young birds were appearing. These Tawny Owlets were exceptionally early and would huddled together for warmth on cold mornings:

Very young Moorhens, on the tiny Churchilll Hospital balancing pond

The local Pheasants provided regular entertainment, displaying from mounds on Southfield Golf Course, before literally pulling chunks of feathers from each other

When seen, Muntjack Deer usually freeze, then run. This male, choose a different approach, by attempting to hide in low vegetation, just off the main path in the Lye Valley. I walked past and noticed the glowing white horns. I took a few pictures, then moved away:

In many ways, this was a spring of hunkering down in first cold, and then very wet, conditions. The second Sedge Warbler for the area was found singing on 27th April. A Kingfisher was seen twice on Boundary Brook, on 1st and 6th May, the latter sighting by myself and Dave Lowe, as he carried out his biannual Breeding Bird Survey for the BTO. This Kingfisher was the 99th species of bird recorded in the Lye Valley area on eBird. The full illustrated list of birds seen in Lye Valley and Warnford Meadow can be found here. What, and when, will be species number 100?

An April Snowstorm

On Monday 12th April I awoke to astonishing scenes. Not only had there been a significant overnight snowfall, but intensely heavy snow was still falling. I staggered out to Warneford Meadow to begin my daily pre-dawn search for migrant birds, but could hardly see across the meadow for the snow:

The view across the trees of the Lye Valley, towards the Wood Farm towerblock, from the golfcourse. This is April!

I was in a state of shock. The conditions were more like the Cairngorms (though with less crampons, see here). Needless to say, bird activity was severely reduced by the heavy snow. Indeed, the only bird of note was a fly-over Grey Heron, nicely illuminated from below by light reflected from the fallen snow:

I wondered what effect such heavy snow would have on the blossom of the many trees, just in bloom?

And how would the insectivore bird species possibly find anything to eat in such alien conditions? My questions were answered as I approach a pair of silver birch trees at the south end of the golf course. Incredibly, both trees were alive with phylloscopus warblers, feeding in the snow-covered branches:

I came to a conservative total of at least 8 Chiffchaffs, but the trees were filled with constant movements. Some of the Chiffchaffs had snow frozen to their feet as they moved through the trees:

But best of all were 2 Willow Warblers, both singing frequently. To stand in heavy snow, at times a near white-out, and listen to the liquid, descending notes of summer left me almost unable to reconcile what I could see, with what I could hear, my senses conflicted.

A Willow Warbler, feeding and singing, in heavy snow.

By 7:30am the snow had stopped falling. With the temperature just above freezing, the melt began. I was lucky to glimpse one of the local Tawny Owls, left absolutely bedraggled by the snowstorm:

Other birds appeared completely untouched by the snow. This Eurasian Jay perched for a moment on a branch above the stream, absolutely pristine in pink, blue and black. The colours were back.

By late morning, after taking my daughters’ sledging, the sun was out and most of the snow was gone, as though it was never there at all. The bushes were filled with singing Blackcaps and Chiffchaffs and there were insects in the tree blossoms. The early morning white-out was a monochrome memory.

Sky-listening: scooters and scoters in Oxford

Common Scoters are sea ducks. Their winters are spent off the UK and Irish west coasts, they migrate to Scandinavia and Russia to breed in arctic pools in the permanent daylight of the northern summer. As such, they spend most of their lives well away from land-locked Oxfordshire. Small numbers of Common Scoters appear in Oxfordshire in spring, mid-summer and autumn (see here for a few more details). The majority of records come from the county’s largest waterbody, Farmoor Reservoir, as birds drop in during their migration.  Common Scoter migrate at night and are perfectly camouflaged. The males are sooty black, the females dark brown. They will not be seen at night. Fortunately, they have evolved to make frequent and distinctive flight calls to each other. It is these calls that betray their presence in the night sky. And until up to 2019 that was the story of Common Scoters in the Oxfordshire. Then came the global covid pandemic.

Common Scoters, Bolt Tail, Devon, August 2020

By late March 2020, hundreds of birders were forced to be at home in the first national coronavirus lockdown. As news broke that a significant nocturnal movement of Common Scoter was occurring across northern England, lockdowned birders across the rest of the country began listening out for the flight calls of Common Scoters. Something was happening. It became apparent that Common Scoters not only used the Wirral-Humber flyway in northern England, but also the Severn-Thames flyway across southern England, and in fact, were being reported right across southern England as they migrated east overland (see here).

As early spring 2021 came around, Isaac West and I discussed the possibility of trying to hear Common Scoters on nocturnal migration from our local patch of the Lye Valley and Warneford Meadow in Headington, Oxford. This area, comprising of a local nature reserve, a meadow and a golf course has no open water and until 8th March 2021 over 368 patch visits had only produced one species of duck: Mallard. The 8th March saw a flock of 7 Goosander flyover, a completely unexpected new species for the area and a remarkable record. Even so, trying to add a species of sea duck to this list seemed like complete madness. But the first covid spring of 2020 had taught us something: the skies are alive with the sound of scoters. Sometimes.

This week we spent three evenings, socially distanced, on Southfield Golf Course listening to the sky. Isaac prefers the expression “live noc-mig”, but I like “sky-listening”. Like “sea-watching”, it captures what you actually spend most of your time doing. Almost immediately I heard the sound of Wigeon passing overhead. A satisfying start and duck number three for the Lye Valley area! Shortly afterward, we heard the sound of a very loud scooter revving up and driving through east Oxford. But above it, the flight call of a Coot:

Scooter and Coot (at the 3-4 second mark). Nocturnal flight call, Southfield Golf Course, Oxford 23rd March 2021. Recording by Isaac West.

So we had scooter, but not scoter. The best moment of the evening was at 21:30 when the first Barn Owl for the area hissed at us:

The first 90-minute sky-listening session had produced three new species for the area. I was hooked. With little wind forecast for the next night, we tried again on Tuesday 23rd March. Very early on we both heard the pyu-pyu-pyu calls of a migrating Common Scoter flock. They were very distant, to the east, so distant in fact that Isaac’s recorder did not pick up the calls. Success, but we wanted proof. We wanted a recording. We tried again on Wednesday 24th March. It was desperately quiet, not even a Redwing called. By 21:30 we were both cold and about to give up, when the ringing calls of Common Scoter were heard again, this time from the west. The flock passed over, heading east, but was just loud enough to be audible on the recording:

Scooter and scoter were in the bag! You don’t need special equipment to hear these migrating flocks of sea ducks. Although distant, both the flocks we heard on the nights of 23rd and 24th March were quite clearly audible over the sounds of east Oxford. An overhead flock would be quite an experience.

Find a quiet spot on a still night, be familiar with the flight call (Teal and other duck species are also on the move at night and are also vocal) and be patient. We spent a total of 4.5 hours listening across three successive evenings to hear the two Common Scoter flocks pass over. Last year the major movement of Common Scoter across England occurred in the first week of April, so we may not be at peak scoter yet. The next few weeks provide a real opportunity to get Common Scoter, an arctic-breeding sea duck, on your Oxfordshire patch and garden lists. Incredible stuff.

Birds of the Lye Valley: the end of winter, 2020/21

The winter of 2020-21 will forever be associated with the covid pandemic. But as we emerge from the grimmest winter this country has faced since the Second World War, we should also remember that this winter has been the coldest in the UK since 2010. The early part of the year saw snow in the Lye Valley and Warneford Meadow:

Cold weather can also force some bird species to move in large numbers to find easier feeding grounds. There was a significant movement of Lapwings across Oxfordshire and Buckinghamshire on 13th February, including the first Lapwings recorded over the Lye Valley. Isaac West counted 165 on that day, all moving south-west, to escape the cold weather:

The resident birds were forced to try to survive the freezing temperatures, including this roosting Tawny Owl and the Jay, below:

But despite the temperatures, increasing daylight also stimulated birds to begin breeding behaviour. There was a singing Blackcap in Boundary Brook on January 23rd in temperatures well below zero, the earliest recorded singing warbler in the Lye Valley area. This was almost certainly a lingering wintering bird from central Europe that was inspired to sing, rather than one of our breeding birds, which in late January should still be in Spain. We await the return of these birds in late March and early April, when the valley will be filled with their song:

Other unusual winter-singers, included two Redwing in song on Southfield Golf Course on 6th March:

This winter has been very good for small finches, with small numbers of Lesser Redpolls present and up to 50 Siskin in the Lye Valley, including this male.

By early March many bird species were in song or demonstrating territorial breeding behaviour. The display flight of Stock Doves could often be seen, flashing their iridescent neck feathering:

This Long-tailed Tit was gathering lichen from tree branches to begin nest-building:

Up to three male Great Spotted Woodpeckers could be heard drumming:

These two male Pheasants spent a morning displaying to each other on the golf course:

Early Spring is also characterised the overhead migration of waterbirds. The usual Canada and Greylag Geese have both been recorded in March, but far less expected was this flock of 7 Goosander, seen flying over Warneford Meadow on 8th March:

With spring in the air and birds on the move, the next six weeks could be one the most productive periods of bird migration in the whole year. After the long cold winter and the covid pandemic, we need some spring days, warm temperatures and hopefully, some superb spring migration over the Lye Valley and Warneford Meadow.

Frozen fungi and the first song

This morning dawned cold, with frost crunching underfoot and a light mist clinging to the coldest areas. The early winter gold and browns of Warneford Meadow, above, turned white at least until the sun burnt through. On the golf course, ice crystals coated the grass blades and froze fungi into tiny cut glass mushrooms:

Some of the larger fungi, protected from above by tree branches, remained frost free:

The Fly Agaric mushrooms, which could be found beneath the Silver Birches of the golf course until late October, have long gone:

A pale shape, high up in a hole in a poplar tree, revealed a sleeping Tawny Owl. The pale feathering above the eyes may help break up the bird’s outline and provide camouflage:

This may be one of the birds that bred locally, pictures of an adult and fledged chicks can be seen at the end of this post from May.

This morning was a good morning for raptors too, though the low temperatures meant that most were sitting perched awaiting the warmth of the sun. A male Kestrel sat in willows near the Churchill Hospital pond; a Buzzard brooded on a tree on the golf course and this female Sparrowhawk sat unobtrusively above Boundary Brook:

Being larger raptors, the local Red Kites sat out on more prominent perches, catching the cold November sun:

This has been a much more productive winter for thrushes and finches than last winter in the Lye Valley and Warneford Meadow area. In the winter of 2019-20, I struggled to record single figure numbers of Fieldfares, Siskins or Redpolls. This winter all have returned in good numbers. Siskins have been recorded in flocks of up to 35, Lesser Redpoll is frequently recorded and there are up to 50 Fieldfares and between 50-100 Redwing present during most visits this month. The thrushes, including this Mistle Thrush and the Redwing below it, are drawn to the holly berries:

But even as the nights draw in and the days approach their shortest length, some birds are preparing for the next breeding season. On 16th November this Song Thrush became the first singing thrush recorded since mid-summer. This morning three were in full song. There are four weeks to go before the shortest day, but for some, spring is already on the way.

Tree Pipit: calls, evidence and birds.

Two recent local patch visits have produced a species that I spent much of last August listening and looking for, but without success: Tree Pipit. This species is a scarce migrant in Oxfordshire, but one that has history in this area. I spoke to Steve Heath early last year. Steve grew up in Cowley and used to watch the Southfield Golf Course area many decades ago. Steve told me that Tree Pipits used to be regular up on the golf course and even now I could see why. The open grassy spaces on top of the hill, the many mature pine trees combined with the sandy bunkers on the golf course, look as if they could tempt a passing migrant Tree Pipit down to investigate.

There was a significant movement of Tree Pipits across England in late August 2019, but despite many hours of observation by myself and Dave Lowe we did not record a Tree Pipit in the Lye Valley area. Last week I was in south Devon and saw, heard and photographed a number of Tree Pipits as they migrated down the coast. Their calls were fresh in my memory as I headed out on Tuesday morning.

Devon Tree Pipits

First encounter: no confirmatory second call

As I descended from the golf course towards the trees of the Lye Valley on 25th August, I was stopped in my tracks by a buzzing “tzeep” flight call of a bird passing high overhead. I immediately called out “Tree Pipit!” I scanned the skies, cupped my ears and listened out another flight call. It never came.

I have long since stopped identifying birds on the basis of “what else could it have been?” If I find myself going down that particular avenue, it simply means that I have not gathered enough evidence to confirm the identification of the bird in question. There must be evidence from my own observation to substantiate the identification. Identification based on ruling everything else out that is not present, is by definition, much less secure.

I reflected that had I been on the Devon coast I would have simply added Tree Pipit to my eBird list and carried on. But in an Oxfordshire context, Tree Pipit was a new species for the Lye Valley area and a species that I had neither seen nor heard in the county. I needed more evidence. I needed the confirmatory second flight call. The one you hear when you are fully alert and listening. Not the first flight call, that can catch an observer unawares, where the mind can play tricks or the wind can distort the call of a more common species. For me, I needed to hear more than one call to reach a satisfactory evidence threshold to add a new species to my patch or county list. I gritted my teeth and headed into the woods.

Second encounter: the confirmatory call!

About eight minutes later, as I passed between the Churchill Hospital and the 18th green of the golf course (this is a strange local patch), I was stopped in my tracks by an explosive buzzing flight call from a bird high overhead. Again I stopped and scanned the skies and listened and this time the flight call was repeated as the bird moved south, sounding just like this recording:

[Albert Lastukhin, XC495491. Accessible at www.xeno-canto.org/495491]

It was a Tree Pipit! And I had heard the second confirmatory call. The one that for me, reduces the risk of an overactive imagination or wind distortion and nails the ID. Tree Pipit was on my patch and county lists. I went home a happy man.

Third encounter: “chip” calls

This morning I was back on the golf course at first light. I was unnaturally optimistic about finding a Redstart for some reason, but as usual drew a blank. As I searched the southern end of the golf course I once again heard the distinctive sound of a Tree Pipit’s standard flight call. This time it was relatively low and I managed to photograph the bird as it circled around overhead.

I watched and listened to it fly over the hilly southern edge of the course before losing sight of the bird. Then I became aware of some high pitched “chip” calls coming from a pipit-like bird flying back north over the golf course. These calls were unfamiliar to me. About 15 minutes later the bird making the “chip” calls flew back overhead, before inserting a classic Tree Pipit flight call between the chips notes. The “chip” calls were Tree Pipit alarm calls, just like this recording:

[B Whyte, XC566189. Accessible at www.xeno-canto.org/566189.]

The Tree Pipit continued flying east and I watched it leave East Oxford and fly until it was lost from view. An instructive morning and a small ambition fulfilled. It is good to know that this hilltop golf course in Oxford city can still attract migrating Tree Pipits in autumn.

Birds of the Lye Valley, Spring 2020: uncommon and rare species

This blog post looks at some of the more uncommon bird species recorded in the Lye Valley area of Headington, Oxford in spring 2020.  It was a phenomenal spring for unusual birds!

Daily coverage revealed that both scarce and rare birds pass through this area, including some entirely unpredicted species. 63 species were recorded in April 2020 alone, out of a total of 81 species recorded ever. I saw the remarkable total of 6 new species for the area in April, meaning that nearly 10% of the species recorded were new for the Lye Valley area. In many ways, there may never be another month like April 2020.

Late March and early April see many species of waterbird take to the wing, moving towards their breeding areas. All the new species added to the Lye Valley patch list in April were birds that breed on or near water. The eBird list for April 2020 is here.

The month began with a regular Little Egret, that could be found feeding in the Lye Valley pools at dawn:

On 3rd April, two Little Egrets were seen to fly in from the west, presumably roosting somewhere near the River Thames. Both landed in trees above the Lye Valley pools:

Red-legged Partridge continued their odd pattern of occurrence. This species has only been recorded in late March and early April, a pattern more typical of migrating birds passing through, though partridges are not known for migration.

My first Mute Swan for the Lye Valley area flew over my head on 11th April:

Sub-adult Mute Swan, over the golf course.

April 12th, Easter Sunday, was a very memorable morning. The unmistakable insect-like song of a Grasshopper Warbler could be heard from Warneford Meadow:

Above, a recording of Grasshopper Warbler, Warneford Meadow, by Isaac West.

Not only was this the first Grasshopper Warbler for the Lye Valley, but it is a remarkable record within Oxford city. It was also the equal earliest Grasshopper Warbler recorded in Oxfordshire this year, another was heard singing in Radley on the same morning (per Ian Elkins).

Shortly afterwards, Issac West found the first Sedge Warbler, singing by the tiny Churchill Hospital Balancing Pond. This bird remained for at least a week:

Sedge Warbler, Boundary Brook Valley, 12th April.
Raven, Lye Valley 16th April. With only 4 records in the whole of 2019, there were 4 records in April 2020 alone.

Any species of wading bird is a rarity in the Lye Valley area. Indeed, the only species of wader on the Lye Valley list before April 2020 was a Woodcock, in November 2019. I have often wondered what the next species of wader recorded would be, Lapwing perhaps? With no suitable habitat any species of wader would be like gold dust. As such, nothing prepared me for the shock of seeing two noisy Oystercatchers flying up from the golf course at dawn on 19th April:

Oystercatchers, Southfield Golf Course

This may be the pair that have been regularly recorded on Port Meadow. A pair of Oystercatchers were recorded over Iffley Meadows early the same morning (per Steve Roby) and were seen to fly into Port Meadow late morning (per Dave Lowe). These birds flew over the Lye Valley and away to the north-east, calling loudly:

I was delighted at having recorded Oystercatcher over Headington. But things were about to get much better: on April 25th all my wader dreams came true. Four medium-sized wading birds flew rapidly over the golf course, heading north-east. Fortunately, I managed to grab a few pictures of the birds before they disappeared, the images would prove crucial in confirming their identity. Astoundingly, the birds were 4 Bar-tailed Godwit:

A full write up of my most remarkable 11 seconds in the Lye Valley can be found here. The record has been confirmed and accepted by Ian Lewington, the Oxfordshire County Recorder.

The first Cuckoo for the Lye Valley flew over on 24th April, albeit silently. More satisfyingly, a male Cuckoo was also heard calling on 3rd May. This still remains a rare bird in Headington. Hobby is more frequently recorded, but is still uncommon. The bird below flashed over the golf course on 1st May:

All in all, a superb spring of local patch birding, at the end of my road. There may never be another like it. The full illustrated list of all bird species recorded in the Lye Valley and Warneford Meadow area can be found here. Now, what will summer bring?

Birds of the Lye Valley, Spring 2020: common species

Spring 2020 will forever be associated with the coronavirus pandemic. With the country in lockdown, I was unable to work. As such, I took my daily walk at dawn and recorded as many bird species as I possibly could in the Lye Valley, Warneford Meadow and Southfield Golf Course area. These areas surround the Churchill Hospital and Old Road Campus, both of which are actively involved in helping the fight against the pandemic.

Below, Warneford Meadow at dawn in April 2020. My overriding memory of spring 2020 will be the crystal clear visibility and the intense (aircraft-free) blue skies:

This blog post covers some of the common bird species recorded in the Lye Valley area in Spring 2020. I made 46 consecutive dawn visits in the period from late March to early May. More coverage generally means more birds and this certainly proved to be the case. In April alone I recorded 63 species. For context, 71 species were recorded in the whole of 2019. Below are some photographic highlights of the common species of birds in the Lye Valley. The next post will examine some of the more unusual visitors.

Sub-adult Grey Heron, Lye Valley. This young Heron was a regular feature of the Lye Valley in April.
6 Cormorants pass below the setting Moon at dawn, 14th April. April is Cormorant month here, with regular sightings of birds flying overhead. They are rarely recorded in any other month of the year.
Displaying male Sparrowhawk, using “slow-motion” wing-beats.
Male Kestrel, one of the local pair.
Red Kite
Male Pheasant: a frequently heard species, but rarely seen. At least two pairs stay hidden in thickets in the area.
A pair of courting Stock Doves, a small number of pairs breed in the area.
Male Great Spotted Woodpecker, drumming in the Lye Valley. Woodpecker drumming was the dominant sound of the woodland in April, but ceases later in the month as the birds move onto the next phase of their breeding cycle.
Eurasian Jay, Lye valley
Nuthatch, collecting mud for the entrance of the nest hole, Boundary Brook Valley
Singing male Grey Wagtail, Churchill Hospital Balancing Pond, March 2020.
Singing Chiffchaff, Boundary Brook Valley.
It was a good year for Willow Warblers, with up to 4 singing birds present. All these birds seem to move through though, with none remaining to breed.
Male Blackcap, collecting nesting material, Lye Valley. The dominant warbler species. The Lye Valley is filled with Blackcap song in spring and early summer.
Garden Warbler: much less frequent than Blackcap, but the odd pair may breed locally.
