Common eiders (Somateria mollissima) in the breeding season on Texel, the Netherlands. The common eider (pronounced / ˈ aɪ. d ər /) (Somateria mollissima), also called St. Cuthbert's duck or Cuddy's duck, is a large (50–71 cm (20–28 in) in body length) sea-duck that is distributed over the northern coasts of Europe, North America and eastern Siberia.
The black-bellied whistling duck is a common species that is "quite tame, even in the wild". [16] It is highly gregarious, or social, forming large flocks when not breeding, and is largely resident apart from local movements. It usually nests in hollow trees (in South America many times in palm trees).
The nest is a depression on dry ground, often some distance from water. It is lined with grass and down and is hidden in vegetation. The clutch is 7–9, cream-colored eggs, which measure on average 52.9 mm × 37.5 mm (2.08 in × 1.48 in) and weigh 43 g (1.5 oz).
The adults can take flight to escape terrestrial predators, but nesting females in particular may be surprised by large carnivores such as bobcats. [12] Large birds of prey, such as northern goshawks, will take ducks from the ground, and some falcons, including the gyrfalcon, have the speed and power to catch flying birds. [20]
