Worlds Largest Gull Visits Wanstead

The long Easter bank holiday didn't quite live up to expectation on the patch, due in part to the weather being clear, sunny and warm - great for topping up my suntan but not so great for grounding passage migrants to an urban London site. On the two visits I did managed to squeeze in, I added Yellow Wagtail, Common and Lesser Whitethroat, Sedge Warbler and Great Black-backed Gull to the Year List.

While the focus was always on returning passage migrants, the two Great Black-backed Gulls (a 4th and 2nd calendar year birds) on Alexandra Lake were a bit of a highlight - it's only taken me four months to add one to the patch year list! Great Black-backed Gulls are usually only recorded as winter flyovers at Wanstead as they commute between the River Thames and the chain of Lee Valley reservoirs, so to get a couple of these big chunky gulls in spring on the deck and in different plumage's was a nice distraction from looking at the current crop of non-breeding mix of Herring and Lesser Black-backed Gulls which are now set to spend their summer on the Flats.

  1. The top image is clearly not adult yet with that bill colour + still lots of brown feathers in the wing.
