The Ruddy Duck is recognizable by shape alone, with a swooping bill, thick neck, chunky body, and cocked tail. The rich, rufous male accents his fine plumage with a cartoonish courtship display in which he whacks his bill against his breast feathers to create a little swirl of bubbles.

Ruddy Duck
The Canadian population of Ruddy Duck is concentrated primarily in the Prairie Pothole region, with smaller numbers as far north as southern Yukon and Northwest Territories, and scattered occurrences in Ontario and Quebec. The wintering range ranges from southern British Columbia across the southern United States to Mexico and the Caribbean. There are approximately 430,000 individuals breeding in Canada, representing 33% of the global population and a moderate degree of responsibility for Canada. The Waterfowl Breeding Population and Habitat Survey indicates that the population has more than tripled since 1970, but confidence is only medium, as the Breeding Bird Survey shows little change over the same period. The national population of Ruddy Duck is within its goal range.
The Canadian population of Ruddy Duck is at least moderately well monitored by three programs. The Waterfowl Breeding Population and Habitat Survey (WBPHS) and Breeding Bird Survey (BBS) both offer highly reliable trend estimates for Ruddy Duck, but the WBPHS is considered the primary source because it is particularly well suited to monitoring waterfowl and focuses on the core of the breeding range. The continental Christmas Bird Count (CBC) trend also provides some insight, but is less reliable for the Canadian population, as many of the individuals in that sample are from the United States population. The WBPHS shows a large increase of 113% relative to 1970, whereas the BBS trend of 21% is within the range of little change. The moderate increase of 52% indicated by the CBC is intermediate, but not as reflective of the Canadian population as the other sources.
The goal for Ruddy Duck is to remain at or above its recent population level, based on the Waterfowl Breeding Population and Habitat Survey. Trend data show that Ruddy Duck is currently within its goal range.

The Ruddy Duck is recognizable by shape alone, with a swooping bill, thick neck, chunky body, and cocked tail. The rich, rufous male accents his fine plumage with a cartoonish courtship display in which he whacks his bill against his breast feathers to create a little swirl of bubbles.
Ruddy Duck is reported nearly uniformly through the spring, summer, and fall in Canada, with a drop in observations during winter when many move south.
