Abnormal Plumage Survey

December 15, 2011 at 10:55 am Leave a comment

BTO’s Garden Ecology Team regularly receives reports of birds whose feathers have gained unusual colourations.  These range from white (leucism/albinism), black and brown (melanism), red (erythrism) to yellow (flavism).

BTO wants your help to explore which of these conditions are most common, the species most frequently affected and where these birds are found.

If you have ever seen a bird with abnormal plumage in your garden, please submit the details through the Abnormal Plumage Survey.

You can also post your pictures on the GBW Flickr stream.
