PLEASE NOTE: Not all COSEWIC reports are currently available on the SARA Public Registry. Most of the reports not yet available are status reports for species assessed by COSEWIC prior to May 2002. Other COSEWIC reports not yet available may include those species assessed as Extinct, Data Deficient or Not at Risk. In the meantime, they are available on request from the COSEWIC Secretariat.
The Loggerhead Shrike is a medium-sized songbird, about 21-23 cm in length. Males and females are similar in appearance. The top of the head, back and rump are dark grey; the underparts are white to greyish. The wings are largely black but a white wing patch is conspicuous in flight. The tail feathers are black, with some tipped with white. A black facial mask covers the eye and extends over the beak. The Loggerhead Shrike is notable for its raptor-like beak, and predatory and impaling behaviours. It may also be useful as a bio-indicator or ‘flagship’ species for grassland birds of high conservation concern.
In eastern Canada, this grassland bird species has been experiencing large-scale population declines and range contractions since at least 1970. There has been a 26% observed reduction in the number of mature individuals over the last 10 years in Ontario. These declines are primarily related to loss of suitable grassland habitat on both the breeding and wintering grounds. The Canadian population now numbers fewer than 110 mature individuals.
Under Canada’s Species at Risk Act (SARA), the foremost function of COSEWIC is to "assess the status of each wildlife species considered by COSEWIC to be at risk and, as part of the assessment, identify existing and potential threats to the species".
COSEWIC held two Wildlife Species Assessment Meetings in this reporting year (October, 2013 to September, 2014) from November 24 to November 29, 2013 and from April 27 to May 2, 2014. During the current reporting period, COSEWIC assessed the status or reviewed the classification of 56 wildlife species.
The wildlife species assessment results for the 2012-2013 reporting period include the following:
Special Concern: 20
Data Deficient: 0
Not at Risk: 1
Of the 56 wildlife species examined, COSEWIC reviewed the classification of 40 that had been previously assessed. The review of classification for 25 of those wildlife species resulted in a confirmation of the same status as the previous assessment.
The Government of Canada is committed to preventing the disappearance of wildlife species at risk from our lands. As part of its strategy for realizing that commitment, on June 5, 2003, the Government of Canada proclaimed the Species at Risk Act (SARA). Attached to the Act is Schedule 1, the list of the species provided for under SARA, also called the List of Wildlife Species at Risk. Extirpated, Endangered and Threatened species on Schedule 1 benefit from the protection of prohibitions and recovery planning requirements under SARA. Special Concern species benefit from its management planning requirements. Schedule 1 has grown from the original 233 to 521 wildlife species at risk.
