Sparrows are the mice of the bird world.
Flocks of sparrows are on the move to, and through, our corner of Yankeeland this week on the Atlantic Flyway. Except for our most common and most distinctive species, I have trouble identifying many of them in the field - even up close.
The subject comes up because I IDed a Swamp Sparrow skulking in my raspberry brambles yesterday. One must admit that these are not particularly distinctive birds, except to the expert.
