The Frontenac Arch region, north of Kingston, Ontario, is a key stronghold for the Endangered Cerulean Warbler. The area supports most of the Canadian population, estimated to be between 430 and 540 pairs. A second, albeit smaller, stronghold is in Norfolk County, in southwestern Ontario.
The Cerulean Warbler has undergone substantial declines across its North American range. It is found in mature deciduous forests with large, tall trees and an open understorey. The loss of old forests over the last century has reduced the amount of breeding habitat available.
Bird Studies Canada is working to fill key knowledge gaps related to occupancy, distribution, and abundance: where are Cerulean Warblers, how many, and in what habitats? Our long-term goal is to track population trends and gather the information needed to identify areas for protection, evaluate conservation actions, facilitate stewardship and, ultimately, help the species' recovery.
