Trends

Trends

significant decrease in southern part of range; unknown status in NWT: Large decrease (>100%) in population since 1970 (Status of Birds in Canada 2014 update, unpublished data provided by H306)(A380) This decrease mostly results from BBS trends, which are not necessarily a good representation of NWT trends.

General Status Rank
Rank: 
Secure
Status Rank Description: 
declines in south may be unrelated to situation in NWT. Small popn size in NWT is not indicative of threat to species wellbeing.but "apparently secure" based on short term trends, ie. >100% decrease in population since 1970, with high reliability data from BBS surveys (Status of Birds in Canada - 2014, http://ec.gc.ca/soc-sbc/oiseau-bird-eng.aspx?sY=2011&sL=e&sM=c&sB=KILL).
S Rank: 
S4
Decision Process Description: 
Drafted as undetermined by Vicky Johnston and S. Carriere mostly based on printed material in 2000; Modified by Vicky Johnston in 2005 to secure.; Reviewed in 2010;no change Reviewed in 2015; no change
