There have been scattered sightings of Snowy Egrets during the breeding season in Atlantic Canada (Parsons and Master 2000). In Ontario, one nest was confirmed (Cadman et al. 2007), and the Manitoba Breeding Bird Atlas (2010-2014) indicated confirmed breeding in one location and possible breeding in four other locations. Data from monitoring programs in Canada are too sparse to infer any population trends. Both increases and decreases have been observed among breeding colonies in the United States (Parsons and Master 2000).
Snowy Egret numbers declined strongly with hunting and plume-collecting at the turn of the century, but showed a strong rebound once conservation measures were implemented (Parsons and Master 2000). A peripheral species in Canada, current threats in the United States include the presence of pesticides and other contaminants in wetland habitats, and abundance may be additionally limited by the availability of suitable nesting habitat (island sites within ~10km of wetland habitats for foraging; Parsons and Master 2000).
Environment and Climate Change Canada and partners have developed Bird Conservation Region Strategies in each of Canada’s Bird Conservation Regions (BCRs). In these strategies, selected species are identified as priorities for one or more of the following reasons:
