During spring and fall migration, Chimney Swifts congregate at communal roosts at dusk and can often be seen entering roost chimneys in large groups shortly after sunset. Join the SwiftWatch Team & help count Chimney Swifts entering Barrie’s 5 roost chimneys. Like many “aerial insectivores” Chimney Swifts have seriously declined in Canada, and our club has undertaken a monitoring role in town.
