Isn't that cool, how chimney swifts do that--cling to the walls of chimneys? Well, I think Terry's pretty smart for supposing that the creatures with the furiously beating wings that fly so fast I can't get a look at them in the early morning are more likely to be swifts than bats.
I'll have to pay more attention to their sound, which may be hard to distill from all the other bird sounds around as the sun is coming up.
Man, it's so hot in here that I don't like to be on the computer for long! I do love summer, otherwise.
