No apologies for posting more photos of these highly photogenic birds - a real treat and almost on my doorstep.

Male (top image) and female (lower image) - this is the first time that I can recall photographic evidence of this species at Fowlmere although their presence has been known for a while - breeding next year?

Redpoll Study
James Hanlon has been carrying out a study on a local Redpoll flock. The following comments are from James.
Not ideal light to assess plumage tone but nothing visible to suggest this is anything other than a lesser redpoll. It has some warm buff tones visible and the pale eye-ring stands out well against the dark brown face.

This bird has a
clean-looking white undertail and has a mealy look about it but lesser cannot
be ruled out. The thick, loose-looking flank feathering might suggest mealy too
but in reality this is probably just an effect of wind displacement of
feathering.
This adult male seems to
look cold and greyish with white underparts and neat flank streaking, and with
a delicate salmon pink wash to the breast it seems initially to indicate mealy.
It is not especially pale however and the fine bill, presence of buff on the
wing-bar and the obvious eye-ring could still point to lesser. Redpolls are all
very close genetically and though proven hybridisation is rare, their general
variability and nomadic habits suggest they could interbreed frequently (this
flock contains a typical mish-mash of confusing individuals!)
This one shows the warm
buffy flanks more typical of lesser but a cold frosty upperpart coloration recalling mealy. Some 1st winter mealy are rather dark and
buff-looking and likely indistinguishable from lesser. This bird however had
rather rounded outer tail feathers and thus appears to be an adult. The frosty
appearance was not obvious in some other photos and there are obvious buff
tones on the wings and rump sides. A pale female lesser is probably most likely
but it's hard to completely rule out mealy (or some mealy influence).
This heavily-streaked bird
is a good mealy candidate, lacking warm tones and with a rather pale head and
long-looking wings. It has obvious whitish stripes on the mantle though this
appears common in both forms. Light conditions and exposure however can change
appearance and it's always dangerous to base i/d on a single photo.
Lesser - Fairly typical individual
Only seen from below, buff
tones suggest lesser.
This bird in flight shows an extensive white rump. Not a great shot but it should prove there's mealy in the flock.

'Redpoll i/d is very
tricky and many individuals cannot be identified with certainty but after refreshing
my knowledge with some articles I've given it a go.' JH
