'Eastern' Jackdaw in the Top Fields
Whilst in early Spring worn Jackdaws can show a narrow pale collar on its lower neck, the pale collar on the individual seen today appeared too prominent being both broad and whitish. Whilst the angle of the bird in the above image is unhelpful in showing the extent of its pale collar, in direct comparison with a Jackdaw, it does reveal the silvery rear-head and nape that are also features associated with 'Eastern' Jackdaw. For a discussion of 'Eastern' Jackdaws and the difficulties posed by the intergrade issue see:

Eventually a superb performer having been kindly called back by Ian Barnard having chosen the wrong time to wander off to look for Gulls at the harbour! Not hearing it call it was nice to see its long hind claws whilst it was perched on the fence effectively eliminating any chance of it being a Blyth's Pipit! Its median coverts and tertials all looked the same generation to me with broad buffy edges so being an adult surely there's a good chance it's the same returning individual seen at the very same site in late March 2014.

Firecrest at Birling
An early Spring migrant whose passage in the County peaks in March.
Female Stonechat in the Hotel Garden
Another early Spring migrant. There was a good arrival of this species today this being the 20th we saw between Birling Gap and the Beachy Head Hotel - exceeded in Spring only by 24 seen on the 4th March 2002. How many went unseen today in Whitbread Hollow and Cow Gap?

Icelandic Black-tailed Godwits in the Cuckmere
I always enjoy witnessing migration in action but as the Spring passage of this species is overland I've rarely seen anything of it apart from grounded birds such as three seen today whilst checking the Gull flock on the current floods in the Cuckmere. However, better was to follow, as whilst watching the three a tight flock of 28 were seen to fly strongly north up the valley until lost to view. Anticipating the three would choose to join them it was a surprise that they didn't.
Eurasian White-fronted Goose in the Cuckmere
With a good few Greenland White-fronts scattered around the Country it's a pity one hasn't been unearthed in Sussex as a twitchable individual would be warmly welcomed and seems well overdue...
Its structure immediately commands attention by virtue of its small pear-shaped head showing a long and low sloping forehead and never-ending lores that combined with its long bill gives the classic snouty expression. Its long thin neck shows the additional 'Adam's apple' bulge at the front. Its rather long and slightly decurved gape line is also visible.
Its long bill appears slim with a weak gonydeal angle and a gently curved tip to its upper mandible. The red spot on its bill is clearly restricted to its lower mandible. Caspian Gull is often described as a gentler looking, more elegant bird than Herring Gull neatly encapsulated by this image.
Males are longer-billed than females and it's hard to imagine they come much longer-billed than this individual! Slightly more side-on it appears flat-backed with only a slight tertial step and is clearly long-winged with only small white tips to its primaries.
Stood at this angle it takes on an ungainly appearance being curve-necked, deep-breasted and showing an obvious ventral bulge.
Whilst near-adult the subterminal dark bar on bill and dark marks on a few of its coverts, restricted dark centres to its tertials and dark marks on its tail age it as a third-year. The combination of its bright yellow bill with a red gonydeal spot and lack of hindneck streaking effectively age it as a third-summer rather than third-winter. Its mantle shade and colour closely resembled nearby argenteus.
Its long spindly legs of a pasty pink complexion give it the typically gangly impression.
On seeing these images a friend described its tiny dark eyes as clearly being pierced by small calibre fire! Traces of dark are just visible on its tail feathers.
Third-summer Caspian Gull in the Cuckmere A fortunate capture with its wings open reveal a small mirror only to p10 and extensive pale tongues on the inner webs of most of the outer primaries. The pale tongues are separated from the tiny white tips to its primaries by a very narrow band of black cutting across p6 to p8 - the oft-described black hooking-back from the outer two primaries as just a black trailing edge. It also nicely reveals its protruding chest, slim-bodied and long-winged appearance.
Barnacle Goose 1 Pale-bellied Brent 1 Black Brant x Dark-bellied Brent hybrid 1 Dark-bellied Brent c.1,200
Based on just the above image this bird would appear to show the most obvious features of a Black Brant namely a large obvious white neck-collar and contrastingly white flanks...
...the above mentioned features are still holding good and easy to infer smoother darker upperparts too...
...the lower border to its white neck-collar appears broad and unbroken and possible to construe its upper border is virtually complete... or is it...
...on enlarging the same image the upper border suddenly appears absent altogether in the centre of its neck...
...an undoubted obvious neck-collar butclearly an incomplete upper border. Its mantle is now appearing rather greyish and lacking any chocolate-brown hint and therefore near-identical to the accompanying Dark-bellied Brent and its flanks are appearing far less contrastingly whitish but taking on a greyish hue...
...in stronger light now appearing near-identical in overall colouration to the accompanying Dark-bellied Brent sharing their greyish upperarts and similar contrast between their black necks and underparts.
Displaying Continental Cormorants near Lewes Brooks
Continental Cormorants P.c. sinensis colonised the UK in the early 1980's nesting in trees and bushes on inland waterbodies. The colony at Lewes Brooks was established in 2002.
Continental Cormorant P.c. sinensis near Lewes Brooks
Apparently pure carbo must have a gular pouch angle of less than 65 degrees and pure sinensis an angle greater than 76 degrees. Reassuringly the above individual's gular pouch angle looks closer to 85-90 degrees. Anything between 65 degrees and 76 degrees is considered not safely identifiable and is thought to include some hybrids. Here's an illustration of the all important gular pouch angle included from Newson et al. "Subspecific differentiation and distribution of Great Cormorants Phalacrocorax carbo in Europe".
