Canvasback duck diving In the early 1950s it was estimated that there were 225,000 canvasbacks wintering in the Chesapeake Bay ; this represented one-half of the entire North American population. By 1985, there were only 50,000 ducks wintering there, or one-tenth of the population.
Aythya is a genus of diving ducks, with twelve species currently accepted. [2] The genus was described in 1822 by the German zoologist Friedrich Boie, with the type species being greater scaup. [3] [4] The name Aythya comes from the Ancient Greek word αἴθυιᾰ (aithuia), which referred to an unknown diving-bird. [5] [6]

They are known to target diving diver ducks such as bluebills (greater scaup), canvasback, goldeneye, scoter and eider to name a few. Layout hunters usually deploy large spreads of diver ducks in open water areas. Many successful patterns have been created for these spreads over the years. Some layout hunters will use as many as 300 decoys or more.
The fastest duck ever recorded was a red-breasted merganser that attained a top airspeed of 100 mph (160 km/h) while being pursued by an airplane. This eclipsed the previous speed record held by a canvasback clocked at 72 mph (116 km/h). [11]
The greater scaup (Aythya marila), just scaup in Europe or, colloquially, "bluebill" in North America, [3] is a mid-sized diving duck, larger than the closely related lesser scaup and tufted duck. It spends the summer months breeding in Iceland, east across Scandinavia, northern Russia and Siberia, Alaska, and northern Canada.
