Kirtland's warbler (Dendroica kirtlandii) COSEWIC assessment and status report: chapter 10
Existing Protection or Other Status Designations
In Canada, D. kirtlandii has been listed as ’Endangered’ by COSEWIC since 1979 (this assessment was confirmed in 1999 and 2000). It is listed under Schedule 1 of the Canadian Species at Risk Act (SARA; Species at Risk Act 2003). The Kirtland’s Warbler is protected by the Migratory Birds Convention Act 1994. In Ontario, the species is also protected by the provincial Endangered Species Act. Were the species to occur again in Québec, it would be protected by the “Act Respecting the Conservation and Development of Wildlife” (which applies to all wildlife species mammals, birds, fish, amphibians and reptiles; D. Banville, pers. comm. 2006). Special provision is given for threatened or vulnerable species and their habitats.
According to NatureServe (2006), the global status of D. kirtlandii is a G1 (globally threatened with extinction, with very few individuals remaining). In Ontario, the Natural Heritage Information Centre (NHIC) ranks the Kirtland’s Warbler as extirpated as a breeding species (SHB), occurring only as a non-breeding migrant/vagrant (SZN; NHIC 2006). In Michigan, the species is ranked S1 or extremely rare at the state level.
