National chimney swift roost survey protocol / Shaffer, F., V. Connolly and C. Maurice. : CW66-777/2022E-PDF
"The Chimney Swift (Chaetura pelagica) is a bird species listed as threatened in Canada under the Species at Risk Act. In Canada, it breeds in Saskatchewan, Manitoba, Ontario, Quebec, New Brunswick, and Nova Scotia. It is rarely observed in Prince Edward Island and Newfoundland during the breeding season. The Chimney Swift mainly uses chimneys in urban and suburban areas as nesting sites and roosts. The gathering of a large number of swifts in flight shortly before they enter their roost allows the birds to be counted at a given site within a relatively short period of time. The present document describes a protocol specifically designed to survey Chimney Swift at roost sites. The implementation of surveys across Canada using a standardized protocol will help to more accurately assess population trends and better guide conservation efforts for this species"--Abstract, page ii.
