The Sharp-shinned Hawk is a tiny but ferocious bird-hunting predator that lives across much of Canada, in both forests and urban area. It gets its name from its sharp, thin lower leg bone, a distinctive feature that distinguishes it from the closely related Cooper's Hawk.

Sharp-shinned Hawk
The Sharp-shinned Hawk breeds throughout Canada's forested regions, and winters across the United States, Caribbean, Mexico, and Central America. There are approximately 240,000 individuals in Canada, representing 24% of the global population. Approximately another 27,000 Sharp-shinned Hawks breeding in Alaska also migrate to or through Canada during migration, increasing the total percentage occurring in Canada to 27% of the global population, which corresponds to a moderate degree of responsibility for Canada. The Breeding Bird Survey shows a moderate increase relative to 1970. Confidence in this assessment is medium because the survey has highly precise trends, but provides only moderate geographic coverage of the Canadian range. The national population of Sharp-shinned Hawk is within its goal range.
The Canadian population of Sharp-shinned Hawk is best monitored by the Breeding Bird Survey (BBS), which samples a moderate proportion of the Canadian breeding range and has high precision in trend estimates, although design suitability is considered moderate due to the potential for confusion with Cooper's Hawk. The national trend showed a substantial increase from the early 1970s to late 1990s, a plateau in the early 2000s, and then a decline over the past decade bringing the population back to late 1980s levels, but still over 50% above its abundance in 1970. Although timing and magnitude of change varies slightly by region, the general pattern of increase and subsequent decrease largely applies across Canada. Six Canadian sites contributing to the Raptor Population Index have trends with medium or high reliability since at least 2000, and all indicate slight to large decreases, in many cases aligning with the the more recent decline indicated by the BBS.
The goal for Sharp-shinned Hawk is to remain at or above its recent population level, based on the Breeding Bird Survey. Trend data show that Sharp-shinned Hawk is currently within its goal range.

The Sharp-shinned Hawk is a tiny but ferocious bird-hunting predator that lives across much of Canada, in both forests and urban area. It gets its name from its sharp, thin lower leg bone, a distinctive feature that distinguishes it from the closely related Cooper's Hawk.
Sharp-shinned Hawk is reported throughout the year in Canada. A dip in the early summer may represent the bird's more secretive behaviour during the breeding season, and the following spike may be caused by the dispersal and migration of young birds.
Nesting period starts between early April and early June and ends between early August and mid-August, depending on the region. Before or after this period, the probability of an active nest is lower.
