Last saturday I did my regular little goosetrip in the neighbourhood. Again I observed big families of Great White-fronteds albifrons with up to seven juveniles! I counted a percentage of 28% young birds (n=343). Defenitely a good polar year! Although I have to take a bigger sample indeed. Amongst them, four whitish ones where present.
Sorry, a crappy pic from my digiscoping camera.
