Hi Josh, I had no idea there was a BBS route through downtown Ithaca! That is fascinating. You may not be able to tell apart immature and adult Chimney Swifts right now, but in another month or so, the adults will be going through active molt of their flight feathers. Any bird at that time with a gap in their flight feathers will almost certainly be an adult bird. The flight feathers of birds hatched this summer will stay with them until they molt them late next summer.
