Golden-crowned kinglet, Discovery Park

This time of year, songbirds tend to rove around in mixed flocks, hopping from tree to tree, gleaning for tiny insects. And usually, if you're in the woods, golden-crowned kinglets will be along, chattering in their high silvery voices. They are tiny - weighing it at 6 grams -- but tough enough to flit and chip their way through New England winters. It's hard to get more than a glimpse of one, because they seldom stay still, always hopping from branch to branch, sometimes dangling upside down, sometimes dodging behind leaves. Many a time I've tried to follow one with the camera. Most of the time I get pictures of feathery blurs or places where kinglets used to be.
Yesterday, I got lucky. This bird was in a mixed flock with black-capped chickadees and dark-eyed juncos.
