Warbler, Canada | Cardellina canadensis
Last Examination and Change: April 2008 (New)
Canadian Occurrence: YT, NT, BC, AB, SK, MB, ON, QC, NB, PE, NS
Status Criteria: A2b
Reason for Designation: Most (80%) of the breeding range of this species occurs in Canada. While regional trends may vary, overall the species has experienced a significant long-term decline. This decline is particularly evident in the case of the species’ Canadian range and there is no indication that this trend will be reversed. The reasons for the decline are unclear, but loss of primary forest on the wintering grounds in South America is a potential cause.
Status History: Designated Threatened in April 2008.
