Trends

Trends

declining on winter counts (VJ4, VJ12; R157); Large decreases (low reliability) recorded in site-specific studies on breeding grounds, stopover sites and wintering grounds. But this does not agree with results from migration monitoring that suggests a large increase in abundance. (Status of Birds in Canada 2014 update, unpublished data provided by H306)
