Birds of the Lye Valley, 2023: the gift that keeps on giving.

Having equalled my all-time total of 81 bird species recorded in the Lye Valley area of Headington in 2022, what would 2023 bring? This area (the Lye Valley LNR, Southfield Golf Course, Warneford Meadow and the Boundary Brook Wildlife Corridor) is surrounded by the housing of east Oxford and has the Old Road Campus and the Churchill Hospital within it. I have had an MRI scan and COVID-19 vaccinations on my local patch, bringing new meaning to the concept of total birding.

January 1st 2023 could have hardly begun any better: 40 species recorded, my best on this date, and a new species for the area – Firecrest – all in the first couple of hours of light. The checklist is here. That the first visit produced 45% of all the bird species that would be recorded in the whole year says much about the variety of urban birding and the patience needed. That first day also saw a flyover Skylark and a wintering Chiffchaff, neither guaranteed in January:

A bitterly cold spell in the second-half of January, covered the local Moorhens in ice…

… but brought in some common winter birds, such as Redwings:

There were also uncommon visitors. The second Common Gull ever flew over, and a Snipe was seen on several visits. January 23rd was a Lapwing day, with 58 flying south in small flocks:

There then followed a superb burst of good birds. Steve Sansom glimpsed a Water Rail on 24th, and I managed to relocate it the following morning, the first for the Lye Valley area:

Two Goosander flew over on the 28th, yet another second-ever record here, one of the themes of the year. This brought the January total to 55 species, and already 63% of the total number of species for the year had been recorded:

February was much quieter, but more new species for the year were added in March, with a flyover flock of Golden Plover on 8th and the beginning of waterbird migration which saw Canada Geese and Cormorants overhead and this Little Egret on the golf course:

And there were Grey Herons, both adults and young birds:

1st April saw the first trans-Saharan migrant arrive, a Willow Warbler, but the spring of 2023 turned out to be desperately quiet, with the only bird of note being a Brambling on April 17th:

Local breeders were all that I had to show for near-daily effort between mid-March and early May:

2023 was a good year for Garden Warblers, with one pair probably breeding:

It was superb to be able to hear Garden Warbler song on most visits between early May and early June:

With the addition of the common Warblers, Swift and Hobby, the year list stood at 74 species by 31st May, the highest total ever reached by this date. This total included the second patch record of Egyptian Geese, as a pair spent a long weekend on the golf course:

But as is often the case, the period between late May and August, the “death zone”, produced no new birds at all. I was reduced to photographing other things:

Fox cub

Emperor Dragonfly, devouring a Small Copper butterfly
I saw this Magpie, presumably feeding on ticks on this male Muntjac, on several occasions.
Juvenile Green Woodpecker

The local Sparrowhawks had a successful season, fledging three young. Only when the first week of August arrived, and with it a returning Lesser Whitethroat, did the year list move on. An excellent January had been followed by a quiet spring and summer, but then came a truly astounding August. A number of Yellow Wagtails were heard and seen flying over. This year I made more efforts to record the flight calls of migrating birds:

This recording of a flyover Yellow Wagtail came out nicely. I like the way the flight call emerges from a background of calling Blue Tits and lawnmowers on the golf course, before the bird passes overhead, typical August birding here:

Nothing prepared me for the next three weeks. On 17th August I found a Corn Bunting on Warneford Meadow, the first Oxford city record since 1980 and the third new species for the Lye Valley in the year. It was quite a moment:

August 30th saw my first, and the Lye Valley’s second, Redstart. It very nearly stayed for a photo…

… and 2 Spotted Flycatchers on the same day:

Both these birds were eclipsed by a superb Pied Flycatcher, the second I’ve found in the Lye Valley area and found on my birthday and was the 81st species for the year, equalling my previous best annual total, so all the more sweet! This bird was one of only three seen in all of Oxfordshire during 2023:

A new Lye Valley area species total was set on September 16th when this Reed Bunting flew over calling. They all count!

The decline of House Martins across the county is very sad. This species has only been recorded in late September in recent years, as small flocks migrate south, passing low overhead in the first few hours of light. This year birds were recorded on September 20th and 23rd. A flyover Lesser Redpoll was species number 83 and was the last regular species that I needed… unless I got lucky with a Woodcock in the autumn. Then a couple of real surprises lifted the total to phenomenal heights. First, a Great White Egret circled over Churchill Meadow, followed a few days later by not one, but two, Great White Egrets and a Little Egret, amazing records for an area with no standing water:

Another flyover finch, the Lye Valley’s second Linnet, was seen and recorded flying south on October 23rd, species number 85:

There was also some decent Woodpigeon migration, with a peak movement of 920 birds in 90 minutes on 20th November:

I only had one target for November: Woodcock. Nearly all the previous Lye Valley records have been in this month, all four of them. On November 18th, in pouring rain, after much tramping through wooded areas, a Woodcock lifted from the ground under the trees by Boundary Brook stream, species number 86 for the year. And that was that. Or so I thought. I still visited regularly throughout December, but held out no realistic hope of adding another species. On December 27th, again in the rain at dawn, I splashed across a very wet Warneford Meadow and was astounded to flush a snipe, from just in front of me, on the edge of this wet patch:

In 573 previous patch visits, I have not flushed a snipe from Warneford Meadow. Even better, this bird looked tiny, rose silently, and flew low and direct into the long grass in the background. Surely this was a Jack Snipe? I walked towards the grass and the bird rose again, this time I got binocular views of it, and noted no obvious white on the trailing edge of the wing and two prominent gold scapular streaks. I thought it would land again, but at the last moment, it lifted off the meadow and flew north, at rooftop height, a stonking garden tick for somebody, if they were quick enough. An end-of-year surprise, species number 87 for the year, a cracking Jack Snipe!

What a year. I visited the Lye Valley area 153 times in 2023, recorded 87 bird species, three of which were new for the area (Firecrest, Water Rail and Corn Bunting). I walked some 800km, or 500 miles, and spent over 230 hours hours birding there. It has been a constant source of joy. Except for the Death Zone. Next year I will walk 500 miles more and will see what I can see. There is a song in there somewhere.
