1cy Common Gull with uncommon tail from Hungary

Post by hieraaetus » Mon Dec 09, 2013 10:56 am

Hi guys,

Here it is a 1cy COGU from Debrecen, Hungary. I took these pictures today. I would like to hear your opinion what the explanation could be for this tail pattern. Advanced moult? Partial albinism?

Thanks in advance.

Cheers,

Gabor
