Would record heat in the Pacific NW motivate Vaux's Swifts to spend the night on tree bark rather than hot bricks. Hard to tell with Monroe Wagner that has had mostly single digits for the last 16 nights. But Selleck is a different story. What follows is our data for the last 15 days showing the Selleck Village high temps and how many swifts we documented going to roost in the Old School House chimney.

We had our 1st Selleck miss this migration. Attempted to catch them coming out the next morning at 5 AM but the wee birds didn't cooperate. Times and the swift's behavior has been remarkably consistent.
