Regular Yellow-legged Gull at Chiswick

This 2cy Yellow-legged Gull has been regular at Chiswick Eyot in recent days. It's quite a distinctive bird with heavily marked scapulars and worn flight feathers - the primaries are quite bleached, for example. Covert moult has commenced, as is evident in the pics below.

I've also had up to three at the Wetlands Centre lately, so they appear to be on the move. This presumably ties in with Lesser Black-backed Gull migration, which also seems to be well underway. Small pulses of birds have been passing through my stretch of the Thames and I had blue-ringed 2cy V.JZ4 last week, which is apparently from Denmark (awaiting details on that one).

Mid-January patch efforts

It remains cold across much of Britain, particularly the south-east, and such conditions usually mean winter birding is at its most productive in London.

It was grey and misty when I headed out late morning. An impressive flock of Tufted Ducks has formed on the Chiswick-Barnes stretch of the Thames, although the amassed group of 101 failed to throw up anything more interesting.

The wetlands centre was pretty decent - great views of two Bitterns including the below individual, which bizarrely stood more or less motionless on the frozen ice in front of Headley Hide for 10 minutes, before slinking off back in to the reeds. A Jack Snipe was flushed by crows just before Wildside Hide, flying around my head a few times before dropping back in to the reeds. I glimpsed a Water Pipit on the grazing marsh and heard the Bearded Tit pinging in the reeds on one occasion. Nine Pintail included six drakes but wildfowl numbers seemed slightly down on my visit the previous week, presumably because of the freeze. A flock of Fieldfares moved through and both Cetti's Warbler and Water Rail were new for the year for me. About 40 Herring, 10 Lesser Black-backed and a few Great Black-backed made up the gull flock.

You ain't fooling no-one, pal ...

That's more like it.

A check of the Hammersmith-Fulham stretch of the River Thames revealed my first Yellow-legged Gull of the year, a rather smart adult, among just 30 or so Herring Gulls. A Little Egret was at Chiswick Eyot mid-afternoon, another new bird for the year for me.

First patch Caspian Gull

I've decided to try and be a little more proactive about my birding in and around London in 2017 - it's about time I accepted that this is where I live, the birding will never be vintage and it's about making the most of what's in front of you.

The first step towards this is of course to adopt a patch. It'll inevitably lead to uninspiring, gull-heavy blog posts throughout the year, particularly given that Larids offer just about the only consistent point of interest in Central London, but I guess it's better than nothing ...

So, my adopted 'patch' will be the River Thames between Barnes Bridge and Craven Cottage, Fulham. This includes Leg o' Mutton (Lonsdale Road) Reservoir, where mature woods and dense patches of scrub should offer a glimmer of hope for interesting passerines at the right times of year. It'll likely end up including Barnes WWT, too, when I finally get sick of counting Herring Gulls and Cormorants on the river itself.

WWT or not, the patch fits comfortably within to the Patchwork Challenge area remit. So, I might as well give that a go too. Happily it'll qualify for the 'green' mini-league as I do all of my birding here either on foot or via bicycle. As such you can expect to find me loitering somewhere near the bottom of the table come December.

In the meantime I paid my first visit of 2017 to this stretch of the Thames today. Highlight was by far and away a third-winter Caspian Gull on the river off Lysia Street, Fulham. This is the same spot where I had an Iceland Gull in early December; birds seem to gather here routinely and it could be a fruitful place if watched regularly.

I identified this bird in the field as a second-winter (3cy) which, if you look at the perched shots, is fairly understandable. It was actually the presence of a green ring on its left leg which gave away this bird's age. Green XDFE was ringed as a chick at Gräbendorfer See in eastern Germany in June 2014. It has only been recorded a few times since, including at Dungeness in September 2014, and this is the first time it's been seen since summer 2015.

Actually there are a few tell-tale signs that this bird is in its fourth calendar year, but these are more apparent in flight. What is really striking is the restricted white in the outer primaries - with the restricted white mirror on p10 only, these look much more typical of a 3cy rather than 4cy bird.

Iceland Gull in Hammersmith!

I went for my first bike ride along the Thames for a couple of weeks this morning in the hope of finding a Caspian Gull. I had a Lithuanian Black-headed Gull at one of my usual spots in Chiswick (I'll blog about this bird at a later date) but only about 30 large gulls, so decided to continue east past Hammersmith Bridge and down towards Fulham.

This turned out to be a good move as I stumbled across a juvenile Iceland Gull among about 80 large gulls on the river adjacent to the Wetland Centre. This was actually the first time I'd biked down here this winter and it was nice to find a new spot for loafing gulls at low tide - Chiswick has generally been poor for numbers of large gulls in the past month.

Eventually the bird showed pretty well, although steadfastly refused to show any interest in the four loaves of bread I threw at it. As such the scope for flight shots was minimal (I only grabbed a few as it flew past me towards Hammersmith) and I had to make do with perched shots at an awful angle and against a typically grubby Thames background.

After about half an hour the bird decided to fly off west upriver, over Hammersmith Bridge (thus in to my regular 'patch'!) before turning north and disappearing off over the West London skyline. It turns out that this is the same bird seen by Pete Alfrey at Beddington on 24 November and then by Dave Harris in the Island Barn Reservoir roost on 28th - not that that's surprising, given that there are so few Iceland Gulls in the country at present.

Chiswick, 16 August

A quick visit to the River Thames by Chiswick Eyot at last knockings on Tuesday evening revealed two 2cy Yellow-legged Gulls among just 25 large gulls. I've been really impressed by the turnover of birds here; both of these are new individuals that I'd not seen before. The usual tactic of lobbing out a loaf of wholemeal brought them to within a few metres at times, but the light was too far gone for any flight shots.

Monday gulls

A short Thames gulling session around Chiswick Eyot on Monday lunchtime produced a juvenile Yellow-legged Gull among at least 110 large gulls. The michahellis was quite a dark and well-marked individual with scapular moult well under way, and clearly a different bird to that seen last week. I also had a juvenile on a brief pre-cricket visit on Sunday, but have no idea whether it's the same bird.

Arguably more interesting, though, was a blue-ringed 2cy Lesser Black-backed Gull. This is the first ringing recovery I've had over four visits in the past ten days, and nice for it not to be a red NTGG job! Suspicions that it was a Dutch bird were quickly confirmed by Roland-Jan Buijs - it was ringed as pullus on 13 June 2015 at Vlissingen-Oost, Zuid-Holland. This is the first time it's been seen anywhere since then.

Gulling in Chiswick

After my walk along the Thames in Chiswick today, I'm slightly embarrassed that I've never bothered to look at gulls here in the summer months before. There are never that many large gulls full stop (normally just a few tens) but, inspired by Rich Bonser's ability to pick up regular michahellis and even the very occasional cachinnans among similarly small numbers on the Thames near his Rotherhithe flat, I decided it was worth a shot today. All I can say is I can't believe I hadn't tried before!

While hardly ground-breaking stuff, I was pretty chuffed with two Yellow-legged Gulls among 60-70 large gulls on the Thames between the Fuller's brewery and the Black Lion pub, a few hundred metres to the east. In fact, I had my first  - a second-summer - within moments of arriving.

Unfortunately it didn't come in to the near-whole loaf of bread I lobbed out, although there was a nice selection of fresh juvenile Herring and Lesser Black-backed Gulls to admire among the c.25 large gulls that joined the melee.

Walking west up to the brewery revealed about 40 further large gulls loafing just west of Chiswick Eyot, including a couple of adult Great Black-backed Gulls. Here I found a juvenile Yellow-legged Gull, which went on to show considerable interest in my bread and showed really well. Sadly I only had a couple of slices left so didn't have much time with it cruising around my head, but I intend to reload on the bread front and head back down at low tide early tomorrow morning.

So a great way to spend to an otherwise sleepy Friday. Suddenly, birding in Chiswick actually seems quite appealing! The only drawback to the gulls here, which give great views, is that you're viewing from the north bank of the river - so on a bright day, light will inevitably be a bit crap. But it's otherwise great - and with Common Terns drifting past, Little Egrets fishing and the usual array of Egyptian Geese to keep you entertained, it's not all that bad for Central London.

The next generation :-)
