Aging a thrush.
10,000 Birds

There is a Rufous-bellied Thrush in a city park in Sao Paulo, Brazil. Actually, there are loads of them, but one is a slightly different version from the type-specific and I have become very fond of it. It stands out from the rest of its flock by virtue of having pure white plumage. He (or it could be a she) is to be found in the tiniest of territories in Ibirapura Park with half-a-dozen of his (or her) more traditionally coloured flock-mates.
