Rusty blackbird (Euphagus carolinus) COSEWIC assessment and status report: chapter 10
Existing Protection or Other Status Designations
The Rusty Blackbird receives no protection under the Migratory Birds Convention Act in Canada, but is protected under the U.S. Migratory Bird Treaty Act. Blackbirds are, however, considered pests in some circumstances and may be killed if they cause damage to human property (Northern Prairie Wildlife Research Center 2004).
Because the Rusty Blackbird is not considered to be at risk in most Canadian provinces, its population is not monitored by conservation data centres or natural heritage centres (M. Donovan pers. comm.). The species has a global rank of G4, i.e., apparently secure (NatureServe 2004; Table 3). The national ranks for Canada and the U.S. are secure. In Canadian provinces, the Rusty Blackbird is generally designated as being secure (Table 3), although some of the Atlantic provinces list the species as vulnerable (NatureServe 2004; Table 3). General status assessments published in 2000 considered the Rusty Blackbird Sensitive in the Northwest Territories, Prince Edward Island and Newfoundland and secure in all other provinces and territories, except Nunuvut, where its status was undermined (Canadian Endangered Species Conservation Council 2001).
