They're here! I saw them on Friday when I was gardening. Three of them so far.
Is there a particular type of tree they go for? There haven't been any at my other house in the Poconos-- is that because of elevation or a type of tree that isn't present there? I noticed they're in the lower elevations near Wilkes Barre, so you could say it's an elevation thing, but up on the mountain, I've never seen them, even in the hottest part of summer. So maybe the trees they like aren't up there?
