Colour-ringed Waxwing
This young Waxwing has quite a back story. It was initially ringed as a first winter male in Aberdeen on 27th November 2010 by the Grampian Ringing Group. It was then refound and photographed by Chris Beach in Welwyn Garden City, 667 KM south south-east of Aberdeen on 10th January 2011. Relocated again in Cambridge by Christoph Zockler on March 20th, it was with a flock of forty birds in Eachard Road, CB3 and had moved back 50 km north north-east of Welwyn. No doubt it is part of the movement of Waxwings now rapidly moving north spurred on by the recent warm weather. J.L.

Cambridgeshire's first 'Greenland' Redpoll?

Note Greenland (rostrata) and Mealy (flammea) Redpolls are lumped as forms of Common Redpoll -following current BOU Taxonomy - along with a further 'Icelandic' race islandica. Icelandic Redpoll closely resembles the Greenland race rostrata though it is usually much paler. Together, Greenland and Icelandic Redpolls are also often known as 'North Western' Redpoll.
Mark Thomas first trapped this putative 'Greenland' Redpoll on March 5th when he was struck by its 'enormity' in the hand, dark tones and heavily streaked underparts. He re-trapped this same bird on Saturday morning when I took these pictures.
In addition to the distinct morphological characters of this bird and the supporting biometrics Mark recorded, we also heard it give a very different call to the more highly pitched tones of other birds present, on release. J.L.
Here the 'Greenland' Redpoll with a 'Lesser' Redpoll (right) for comparison.

Common Redpolls

Mark is currently ringing a mixed flock of more than 100 Redpolls visiting his Gamlingay garden. This migrant flock predominantly contains Lesser Redpolls Carduellis cabaret which occur in Britain, Central Europe and South West Scandinavia. Some 'Mealy' Redpolls like the ones above are also present - these typically greyer-toned birds emanate from Fenno-Scandinavia.
You can see more of Mark's Redpolls and follow his blog here.

Wigeon (possible hybrid)
'This is (probably) the same bird that has been in the Ouse Fen / Berry Lagoon area for the past couple of winters. As you can see, it has extensive green sides to the head, paler areas on the cheeks, and a rather pale forehead flash. However, I can't see any other pro-American features. An odd Eurasian Wigeon or a second generation hybrid?' RT

Reed Bunting
'The image, featuring one of three birds, was taken in a my garden in an urban area of Soham. The Reed buntings have turned up at my feeders in early spring for the last three years running. They usually hang around for a few weeks before departing.'AK

Greylag Goose
John has titled the second image 'Look both ways'. It is certainly an unusual pose.
