The Eastern Screech-Owl is a year-round resident of Canada occurring mainly in southern Ontario, with smaller populations in Saskatchewan, southern Manitoba and Quebec. The Atlas of the Breeding Birds of Ontario suggests that the occurrence of owls increased between the Atlas periods in Ontario (1981/85 and 2001/05). However, there are few data available from outside Ontario, or from before or after the period covered by the Atlas. This species is well adapted to both urban and rural settings and favours wooded areas where it nests in tree cavities or nest boxes. This species has been identified as a priority for conservation and/or stewardship in one or more Bird Conservation Region Strategies in Canada.
Populations are known to cycle (Gehlbach 1995), thus complicating the determination of the species' long-term population status. Predation, low food supply and unusually cold winters can affect the population (Gehlbach 1995). Habitat fragmentation is apparently not detrimental to this species (Gehlbach 1995). The species readily adapts to nest boxes.
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:
