males generally not territorial; several nests may be built in a clump of shrubs

Trends

Trends

National trend = decline, need to confirm for NWT (LA12); Christmas Bird Count is the only survey to monitor this species but the precision of the data is low and the results can not be extrapolated to specific breeding regions. The data should be interpreted with caution. CBC data shows a decline of 5% per year or 40% over the last 10 years. (Environment Canada, 2011. Status of Birds in Canada – 2011 Website, Data-version 2011. Environment Canada, Gatineau, Quebec, K1A 0H3)

General Status Rank

Rank:

Secure

Status Rank Description:

Species is widespread but little data exists to estimate population size. Not enough BBS data to provide trend estimates. Trend data from CBC for the NWT has low precision and should be interpreted with caution however, the trend does indicate the population is increasing. Additionally there are approximately 1,200 ebird records in NWT. These data taken together indicate an apparently secure population.

S Rank:

S4

Decision Process Description:

Drafted by Leslie Wakelyn and S. Carriere mostly based on printed material in 2000; Reviewed in 2005 by Craig Machtans and L. Armer - no change in status.; Reviewed in 2010;no change; Reviewed by Emily Upham-Mills CWS in 2015, no change; Reviewed in 2020 by Amélie Roberto-Charron, modified from undetermined to secure based on Improved knowledge of the species
