I think I try a shot like this almost every year and, every year it is not what I'm hoping to get.
These are some of the little brown birds that cluster in the bushes at the corner of my garden, all puffed up and looking for some shelter from the cold wind.
There are a lot of them and they blend in very well with the branches. If I take it from too far away they don't show up at all. If I take it from too close, you see one or two birds well, but lose the effect of the mass of them huddled there. Sigh...
