Things are looking up!

(An article by Tim Poole for the Fort Rouge Leisire Centre Newsletter)

I am sitting on the grass opposite the Fort Rouge Leisure Centre minutes before sundown in late May, eyes fixed on the large brick chimney at the rear of the building, with the noise of heavy Osborne traffic as background music. I am waiting to see an endangered bird enter its evening roost. This might not seem like an obvious place to find a threatened species but the bird in question may be present in your place of work, leisure, worship or home.

Chimney Swifts are present in Winnipeg from May until August before heading to South America to spend the winter. Since 1968 their population has declined by 95% leading to the Chimney Swift becoming a protected species federally and provincially. This huge decline is linked to the loss of suitable nesting chimneys, as furnaces are modified and chimneys become capped or lined. Prior to the arrival of European-style settlements, Chimney Swifts nested in large dying trees like the cottonwoods along the river. The Chimney Swift has demonstrated a remarkable adaptability, responding to the loss of nesting trees by making use of chimneys. Chimney Swifts show a preference for open, unlined, brick chimneys, a minimum of two and a half bricks across and in close proximity to trees and rivers where they can feed on up to 1000 mosquitoes each day.

At this point I should add that no one need panic. These are birds which have lived alongside Manitobans for over 100 years, yet hardly appear to be noticed. Each nesting chimney will contain a single pair who build a small cup-shaped nest out of dead twigs detached from surrounding trees. In some cases, they use a chimney as a roost, and in these circumstances there may be significantly more birds present.

In a few weeks from now, if you are close to the Leisure Centre around dusk, listen out for light chattering and a small black missile with wings hurtling across the evening sky. Smaller than a House Sparrow, these agile birds are like miniature, chattering, jet planes as they search for food and converse with other swifts. Suddenly a single swift will circle the chimney a few times before plunging vertically headlong into it, possibly followed by other swifts. Other swifts spotted in the evening sky might be roosting in chimneys on Beresford or even over the road in Riverview.

The Manitoba Chimney Swift Initiative was started by Nature Manitoba in 2007 with the aim of monitoring and conserving these special birds in Manitoba. We are keen to get in touch with any local residents who would be interested in monitoring swifts. We are also keen to arrange an evening out at a chimney to show people the swifts entering a chimney. Finally, if you see Chimney Swifts, think they may be using your chimney or would like to receive some factsheets, please contact me as indicated below.
