juvenile Yellow-legged Gulls - July photos

So since the last update, it’s been more of the same. On Sunday morning, I had a pretty impressive count of four Yellow-legged Gulls by my flat in Rotherhithe – an adult and three juveniles. I then headed off to Dungeness and spent an enjoyable afternoon with Mick S and Richard S by the fishing boats – 5 Yellow-legged Gulls (an adult and 4 juveniles) and a first-summer Mediterranean Gull the highlights. Having finished for the summer on Tuesday, baiting the local seagulls (that incidentally haven’t attacked me despite all the media hysteria) today and yesterday produced a single Yellow-legged Gull on both days. I also headed to Greenwich yesterday where on the mud by the O2 there were yet more Yellow-legged Gulls – eight in total (two adults, a first-summer and five juveniles). This included an intriguing juvenile, with easily the palest underwing I’d ever seen on the species: -

Anyway, some of you may be relieved by what I’m going to say now. There’ll be no gull focused posts for a few weeks as I’m heading off for a bit – but for those of you who’ve enjoyed the juvenile Yellow-legged Gull season here are a few of the highlights since 1^st July: -

Since the last update, I've tried to get myself out locally as much as possible. It's a good time of year here in Rotherhithe and it seems also in Greenwich. That is, if gulls are your thing. With quite a few non-birding commitments last weekend, I decided to spend the time I had at Greenwich by the O2 - and along with several ringed gulls, on the Saturday there were eight Yellow-legged Gulls (a near-adult, two 1st-summers and five juveniles) and on Sunday even more - 13 birds (two near-adults, a 1st-summer and ten or so juveniles).

The working week was more hectic than it needed to be given it was the last full week of term; however on Tuesday evening the first Yellow-legged Gull - with yellow legs - in Rotherhithe this year was on the mud by the Hilton Hotel. The next evening there was a juvenile there too, along with an adult Common Gull.

And on to yesterday, Saturday. What is evident now is the upsurge in local juvenile gulls - the mud by the O2 yesterday morning held four juvenile Yellow-legged Gulls, but they were now outnumbered by juvenile Herring Gulls (along with a couple of typically dusky juvenile Lesser Black-backed Gulls).

Back in Rotherhithe, a bit of bread chucking on the River Thames near my flat produced the results quickly - a Norwegian white ringed Black-headed Gull and then two juvenile Yellow-legged Gulls.

So that's that. I'll be heading off to Dungeness shortly for another session of gulls by the fishing boats with Mick S and Richard S...

There was quite a bit of gull movement on the river by my flat this week, especially on Tuesday and Wednesday. Post-work juvenile Yellow-legged Gulls on each day were nice, different individuals and both enjoying the daily rations of bread that I provide!

Compared to the 1st bird, note the more uniform dark tertials and greater barring on the rectrices

This evening, a 2nd-summer Herring Gull with a NTGG ring was on Greenland Dock - a bit of geeking at my spreadsheet when I got home showed that I'd seen it at Dungeness last November!

2nd-summer Herring Gull D9DT - ringed at Rainham Tip, London on 30th November 2013 and then I saw it at Dungeness on 9th November 2014. Nice to be reacquainted!

Hopefully this weekend will be another gull filled one.

If you like Yellow-legged Gulls (and Roseate Terns)...

It's been a busy week or so since the last post. I tried to muster up something last week but the heat here in London sapped any energy I had left after busy days at school (and with London's gulls). It does seem as though there is a bit of post breeding dispersal happening now...

And it started on the hottest day of the year, 1st July. After school, and with a mid evening low tide, I got myself to Greenwich. The inside bend of the meander by the O2 has a load of sediment exposed, and the gulls seem to love it at the moment. So much so, there was my earliest ever juvenile Yellow-legged Gull - a nice fresh bird - along with a second-summer. A handful of ringed birds too, including a Bristol ringed Lesser Black-backed Gull and a couple each from locally as well as Sussex.

And so to the weekend and a return to Greenwich on Saturday morning. Warm again, and the Yellow-legged Gulls were present again with at least two juveniles and a third-summer bird. One of the juveniles was a real brute, naively having a go at the local Great Black-backed Gulls. However Crossness was quiet and scanning through the Black-headed Gulls at the outfall didn't produce, unless a 1st-summer Common Gull counts (which it doesn't!).

Finally on to yesterday (Sunday) and I actually enjoyed waking up to the grey skies and rain. A pleasant respite from the oppressive temperatures of the past few days. I headed down to Dungeness for the afternoon and met up with Mick S and Richard S. Always good to have a chat and sit about with the gulls - some nice bits about too. Not least a couple of really showy juvenile Yellow-legged Gulls; both a bit skittish and keeping away from the main flock a lot of the time.

Added value came in the form of at least a couple of Med Gulls (a first-summer and at least one juvenile) plus some Scandinavian ringed brutish Great Black-backed Gulls and a couple of Thames ringed Herring Gulls.

1st-summer Great Black-backed Gull Dungeness, Kent 5th July 2015. Ringed as a chick at Knogen, Læsø, Nordjylland, Denmark on 2nd July 2014, seen on Terschelling, The Netherlands on 30th October 2014 and then Dungeness from 9th January 2015 onwards - I last saw it on 17th May!

2nd-summer Great Black-backed Gull Dungeness, Kent 5th July 2015. Ringed as chick Lille Vigeskjær, Lindesnes, Vest-Agder, Norway 4th July 2013; then seen at Minsmere 19th July 2014 and Dungeness from 27th July 2014 until last seen by myself on 8th November 2014.

1st-summer Great Black-backed Gull Dungeness, Kent 5th July 2015. Ringed as a chick at Risøy midtre, Mandal, Vest-Agder, Norway on 8th July 2014 and this is the first sighting since.

For most though, the headline bird of the day would have been this Roseate Tern that was lingering for a lot of the time I was present - though it did take me nearly three hours to walk the few hundred yards to see it. Having to withdraw myself from the melee was a real task.

So that's it for another weekend... just a couple more weeks and then the summer holiday party starts.
