The Northern Pygmy Owl may be small, but it can take down prey that weighs multiple times its own body weight. The pair of large eye-spots on the back of its neck likely help help deter potential attackers and may also confuse flocks of small birds attempting to drive this fierce predator away.

The Northern Pygmy-Owl is a year-round resident of coniferous and deciduous forests in British Columbia and southwestern Alberta. The Canadian population is approximately 67,000 individuals, representing 37% of the global population and a moderate degree of responsibility for Canada. The Christmas Bird Count indicates that the Canadian population has undergone a moderate increase since 1970. There is medium confidence in this status, as the Breeding Bird Survey has similar overall reliability but indicates little change over the same period. The national population of Northern Pygmy-Owl is within its goal range.
The Canadian population of Northern Pygmy-Owl is monitored fairly well by both the Breeding Bird Survey (BBS) and the Christmas Bird Count (CBC). Overall, the CBC likely provides a slightly more reliable signal of population trend, as both sources sample a similar proportion of the population, but the timing and design of the CBC is superior for detecting this species. The CBC trend for Canada shows considerable inter-annual fluctuations, but overall a steady increase ever since 1970, amounting to a cumulative growth of over 80%. The BBS trend is more stable, with a total increase of 18% over the same period. Because there is some difference between these two trends, confidence in the moderate increase indicated by the CBC is only medium.
The goal for Northern Pygmy-Owl is to remain at or above its recent population level, based on the Christmas Bird Count. Trend data show that Northern Pygmy-Owl is currently within its goal range.

The Northern Pygmy Owl may be small, but it can take down prey that weighs multiple times its own body weight. The pair of large eye-spots on the back of its neck likely help help deter potential attackers and may also confuse flocks of small birds attempting to drive this fierce predator away.
Northern Pygmy-Owl is reported throughout the year in Canada, with the lowest levels of observation during the summer likely reflecting the owl's secretive habits and habitat during the breeding season.
