Palmate feet – Chilean flamingo. Totipalmate feet – blue-footed booby. Western grebe presenting a lobate foot. Lobate feet – a chick of the Eurasian coot. The great crested grebe. The feet in loons [2] and grebes [2] [7] are placed far at the rear of the body - a powerful accommodation to swimming underwater, [7] but a handicap for walking.
Its most notable characteristic is its blue-colored feet, which can range in color from a pale turquoise to a deep aquamarine. Males and younger birds have lighter feet than females. [2] Its blue feet play a key role in courtship rituals and breeding, with the male visually displaying his feet to attract mates during the breeding season.
Unlike the webbed feet of ducks, coots have broad, lobed scales on their lower legs and toes that fold back with each step to facilitate walking on dry land. [2] Coots live near water, typically inhabiting wetlands and open water bodies in North America .
Both sexes have a pale blue bill with a black tip, a white belly, and gray legs and feet. [10] The wing patch behind the speculum is gray. They can be distinguished from most ducks, apart from Eurasian wigeon, by shape. However, that species has a darker head and all-grey underwing.
The American black duck (Anas rubripes) is a large dabbling duck in the family Anatidae. It was described by William Brewster in 1902. It is the heaviest species in the genus Anas , weighing 720–1,640 g (1.59–3.62 lb) on average and measuring 54–59 cm (21–23 in) in length with an 88–95 cm (35–37 in) wingspan .
Dec. 10—We were driving across the Mount Desert Island causeway the other day when I spotted a group of ducks bobbing in the ocean waves. Flashes of white had me guessing that they were either ...
Their brown color serves as camouflage in the marshes they live in. [12] They do not have white visible under their wings when flying, like other grebes. [13] Their undertail is white [ 11 ] and they have a short, blunt chicken-like bill that is a light grey color, [ 2 ] [ 11 ] which in summer is encircled by a broad black band (hence the name).
They can be distinguished from most ducks on size, shape, and the speculum. Separation from female common teal is problematic. In non-breeding (eclipse) plumage, the drake looks more like the female. It is a common duck of sheltered wetlands, such as taiga bogs, and usually feeds by dabbling for plant food or grazing. It nests on the ground ...
