On Monday I asked:

What kind of bird is this, and what was it doing in this place in Piermont, N.Y., recently?

The answer: It is a Yellow-billed Cuckoo, as several readers correctly replied.

According to Charley West, who is a bit of a cuckoo expert (his license plate is COO X 2):

"If the bird showed up for free meal, I’d say it’s a Y-B Cuckoo- - they’re known
for that!"
