Hi,
just to let you know that on june 28th, 217 Chimney swift were seen entering the chimney of the catholic church in Témiscaming. I received the info by Stéphanie Gagnon from CWS. With that high number, there's no doubt it's a roost, not a nesting chimney.
Témiscaming is located 82km south of Ville-Marie, highway 101.
