COSEWIC Assessment and Update Status Report on the Cerulean Warbler in Canada

Special Significance of the Species

The Cerulean Warbler has generated considerable public, scientific and conservation interest lately. Much of this interest is generated by bird-watching (the fastest growing leisure activity in North America); the Cerulean Warbler is highly sought after by bird-watchers due to its inconspicuousness and beauty. Indeed, bird-watchers were among the first to document localized population declines of this species (Robbins et al. 1992). The positive regard in which this species is held has led to an intense public interest in its conservation.

There is no recorded information from aboriginal traditional sources specific to this species.

While the Cerulean Warbler does not appear to fulfill any critical ecological role (in the sense of a keystone species), it has become a symbol of the health of mature deciduous forests in eastern North America. In Ontario, management of forested habitats for Cerulean Warblers will likely have a positive effect on other species of interest (McCracken 1993). These include the Red-bellied Woodpecker (Melanerpes carolinus), Acadian Flycatcher (Empidonax virescens), Louisiana Waterthrush (Seiurus motacilla), Kentucky Warbler (Oporornis formosus), and Hooded Warbler (Wilsonia cistrina).
