Well good luck to you guys who are going to build them. I wonder what attracts swifts to these structures. They often aren't as tall as chimneys on houses. I'd assume they'd work on Vaux's (just to make sure everyone's clear, that's said "Voe's" not "Vawkses") as well as Chimney Swifts? White-throated and Black would stick to canyons and rugged terrain, right?
BTW, had a Swamp Sparrow at my school, with the lingering Ovenbird. I'm sure my yard would be hopping right now!

I've heard both pronounciations of VASW, but I do use "Voe's". I think it's French, so that is the right way. I know they nest in chimneys, so I assume they would nest in artificial constructions. WTSW is restricted to rocky cliffs as far as I know, and BLSW mainly nests behind waterfalls (Where I've seen them seen them nesting)
Congrats on the school birds! The best I have on my list is a pair of nesting kestrels.
