It's Quiz Night Tuesday!
And tonight's question is, can you ID this bird?
I will post the answer tomorrow night, good luck.
And the answer is:
A leucistic Brambling that we caught and ringed on Sunday.
The BTO's description of leucism is:
In leucistic birds, affected plumage lacks melanin pigment due to the cells responsible for melanin production being absent. This results in a white feathers, unless the normal plumage colour also comprises carotenoids (e.g. yellows), which remain unaffected by the condition. Although leucism is inherited, the extent and positioning of the white colouration can vary between adults and their young, and can also skip generations if leucistic genes are recessive.
The notes on Scouse Ringers blog say "One of the last Brambling out of the nets was this leucistic bird. Capturing birds with leucistic features is not uncommon, in most cases it is single feathers but in this bird it was more extensive and, interestingly, it was symetrical across the body."
I really like Scouse Ringer's new name for it, a Snowling!
