white blackbird

This albino blackbird came to our backyard for a couple of years. It was not as shy as the other blackbirds and did not even fly away from our cat, which actually did ignore it. My mother almost cried when this bird did not return. I guess white blackbirds are a rarity, at least in Germany, where this picture was taken. Whenever I told somebody about it, they did not believe and I had to show them this picture.
