I didn't manage to catch some of the behavior I observed for these little Chipping Sparrows, Spizella passerina. It looks as if they are wiping their beaks on this branch. That may be just what they are doing. What do you think they ate that made them want to clean up?
They are some of my favorite sparrows. They are small, and very common, but endearing. I love their bright chestnut heads. More tame than many birds, they will hang around under windows, on sidewalks, etc. tilting their heads as if listening when you talk to them.
Ah! Now perhaps you can guess what these sparrows were enjoying. See the white "net" behind them? That is a tent caterpillar nest. Even though I didn't get a picture, I can guarantee that there are at least two fewer caterpillars than there were a few minutes previous.
