Reader Andrei Volkov, who lives in Maryland, sent some hummingbird photos, two of which comprise a “spot the hummingbird” set. I’ll put up the first one now; given that it was taken in Maryland, this must surely be the ruby-throated hummingbird (Archilochus colubris), the only hummer that breeds in the state. Can you spot it in the photo below? I’d characterize this as of medium difficulty. (Click to enlarge).
I’ll give the answer at 11 a.m. Chicago time, and try to avoid giving the location in the comments below.
