What is the knocking robin trying to tell us? The commenter that said a knockin' robin had come to their house isn't the only one. Lately I've been seeing more referrers that come here from searching on "knocking robin." And I've gotten two emails.
Maybe this is just a function of my post having risen to the top in google. Or maybe more robins really are knocking on people's windows.
Which begs the question: is it the same robin flying about the U.S.? Could these be offspring of my robin who learned to knock by watching its knocking parent? And whoever they are, what do they want?
