My East Coast friends, astonished at the Monroe Swift numbers, are referring to them as "Sarah Palin crowd estimates".? So how do you count those Swifts?? We watched them last night and agree that thousands entered that chimney but where do they all fit???? Is the thing on the top a counter or a video cam?? Does the rope go to a door you can close?? Do predators ever raid the flock?? In LA Ravens grab swifts near their roost chimney.? We've seen hawks troll through bat clouds to catch bats.? Do the birds nest in hollow trees or smaller chimneys, or both?

Way cool !
