Early spring promise

The mild conditions of recent days have generated a rush of summer migrants, many of which are arriving days (even weeks) earlier than usual.

I had my first Chiffchaff of the year singing at Lonsdale Road Reservoir, Barnes, at sunrise on Friday morning - this quickly followed by the regular 2cy Caspian Gull frequenting the playing fields at Dukes Meadows. I still look at this bird sometimes and shudder a bit, as structurally I think it looks quite Herring-like at times. I guess it's probably from Germany.

It looks fine here, but sometimes this bird takes on an appearance quite unremarkable for cachinnans. I've never seen/heard it calling.

Plenty of gulls have been on the move in recent days - the warm conditions of Saturday and Monday in particular were good for observing visible migration, with Black-heads almost streaming east at times. Not a single bloody Med Gull, though. The wait for one on my patch goes on. A few gull rings included the usual NTGG birds, red-ringed 2cy Herring 'J+H' from Peter Rock's scheme in Bristol, yellow-ringed 3cy Herring 'Y.161' (from Rufforth, N Yorks), and the following two:

 Adult Lesser Black-backed Gull white 'A8CF', Fulham, 11 March 2017 - from Sussex but awaiting details on when it was ringed

3cy Common Gull green 'J88Z', Chiswick, 12 March 2017 
Ringed as a 1cy female at Stavanger, Norway, on 16.11.15 and still in the city environs in Feb 2016, this is the first sighting of it since (and the first away from SW Norway)

There have also been up to three 2cy Yellow-legged Gulls knocking about recently, all familiar birds from recent weeks, but no new Caspian Gulls in recent days.

2cy Yellow-legged Gull, Fulham, 11 March 2017. I first saw this bird at Beddington on 3 March.

Sunday was a real red-letter day. Murky conditions produced a fall of early-spring migrants at the WWT including a pristine pair of Garganey, a Sand Martin, three singing Chiffchaffs and a smart male Northern Wheatear. Meadow Pipit was notable, too. On a sunnier Monday, I had a Common Sandpiper on the river at Fulham.
