Birds Protected in Canada Under the Migratory Birds Convention Act, 1994


Introduction

Most species of birds in Canada are protected under the Migratory Birds Convention Act, 1994 (MBCA). The MBCA was passed in 1917, and updated in 1994 and 2005, to implement the Migratory Birds Convention, a treaty signed with the United States in 1916. As a result, the Canadian federal government has the authority to pass and enforce regulations [Migratory Birds Regulations (C.R.C., c. 1035)] to protect those species of birds that are included in the Convention. Similar legislation in the United States [Birds Protected By The Migratory Bird Treaty Act] protects birds species found in that country, though the list of bird species protected by each country can be different.

"Migratory birds" are defined by Article I of the Convention which names the families and subfamilies of birds protected, and provides some clarification of the species included. This list is provided as a policy interpretation of Article I. Bird species not listed here may, or may not, be protected under provincial or territorial legislation, the Convention on Biodiversity, or the Species at Risk Act (2002). Persons making any decisions regarding the protected status of a bird species in Canada should consult these other statutes. Environment Canada requires that all three criteria below be met to qualify a species for the list of bird species protected in Canada under the MBCA. These criteria do not represent a reduction in Environment Canada's mandate or the families of birds previously protected under the MBCA:

  1. Birds referred to in Article I of the Migratory Birds Convention as amended under the 1995 Protocol, either directly by species name, directly by the listing of their family, or indirectly by interpretation of the original ConventionFootnote 1.
  2. Species that are native or naturally occurring in Canada:
    • A native migratory bird is one that is present entirely as a result of natural biological or ecological processes."
  3. Species known to have regularly occurred in Canada. Although species that occur infrequently (i.e., "accidentals") and that meet criteria 1 and 2 are not included on this list, they continue to be considered as having protection under the MBCA any time they occur in Canadian territory.

In general, birds not falling under federal jurisdiction within Canada include grouse, quail, pheasants, ptarmigan, hawks, owls, eagles, falcons, cormorants, pelicans, crows, jays, kingfishers, and some species of blackbirds.

Three introduced species do not meet criterion 2 but continue to appear on the MBCA list: Mute Swan (Cygnus olor, family Anatidae), Eurasian Collared-Dove (Streptopelia decaocto, family Columbidae) and Sky Lark (Alauda arvensis, family Alaudidae). Environment Canada will consult provincial and territorial governments, who share responsibility for the management of birds in Canada, regarding a proposal to remove these species from the list of MBCA birds. Until a decision is reached by the concerned parties, these species will remain under MBCA protection.

The list of birds protected under the MBCA follows the American Ornithologists' Union's Check-list of North American Birds (AOU 1998), and its supplements to 2014, on matters of taxonomy, nomenclature, and sequence.

Birds in Canada are protected under provincial and territorial statute in addition to the federal Migratory Birds Convention Act, 1994.
