At the April 2018 meeting of the Committee on the Status of Endangered Wildlife in Canada (COSEWIC) in Windsor, Ontario the status of six birds species in Canada was reassessed.

The Streaked Horned Lark and Coastal Vesper Sparrow are two subspecies of the Horned Lark and Vesper Sparrow, respectively, native to the southern coast of British Columbia. Both of these subspecies have previously been assessed as "endangered" and are historically rare in Canada. Unfortunately there is no evidence that a breeding population for either subspecies exists in Canada. There are breeding populations in the United States. It is hoped that recolonization from the United States is possible if the remnants of their habitat can be protected and restored in Canada.

Chimney Swift

Due to a substantial decline in distribution and abundance the Chimney Swift was first assessed as "Threatened" in Canada in 2007. Data suggest the observed decline has accelerated during the past decade in Canada. However, data from urban roost counts in recent years indicates signs of hope. The Chimney Swift remains "Threatened" in Canada for now. Through bird studies like SwiftWatch in Canada it is hoped the monitoring of data trends will provide a clearer picture of the Chimney Swift's future.

Common Nighthawk and Olive-sided Flycatcher

The Common Nighthawk and Olive-sided Flycatcher are found in all territories and provinces of Canada. In 2007 these two species were assessed as Threatened based on a steep declines in there populations in Canada. During the past decade the decline in their populations has slowed down. Because there are large populations of both species over extensive ranges throughout Canada, the status of the Common Nighthawk and Olive-sided Flycatcher has been reassessed as "Special Concern".

The Red-headed Woodpecker is not faring well in Canada. In 1996 the Red-headed Woodpecker was first assessed as a "Special Concern" and later in 2007 that assessment was changed to "Threatened". The Red-headed Woodpecker has now been changed to "Endangered" in Canada. It is estimated that the population in Canada is less than 6,000 mature adults. The trend in population is strongly negative along the border with the United States which reduces the chances of the population in Canada recovering.
