Hybrids between the lesser scaup and the redhead (A. americana) are recognizable by the lack of contrast between wings and belly and the dull brownish ...

These are gregarious ducks, mainly found on fresh water or on estuaries, though the greater scaup becomes marine during the northern winter. They are strong fliers; their broad ...
The 2010 American scaup population survey was 4.2 million scaup, [36] however, the worldwide greater scaup population survey estimated 1,200,000 to 1,400,000 mature greater scaup. [19] Along with the aerial population surveys, there is a ringing programme for the greater scaup. Metal leg bands are placed on them, so that if the scaup is killed ...

The family Ardeidae contains the herons, egrets, and bitterns. Herons and egrets are medium to large wading birds with long necks and legs. Bitterns tend to be shorter-necked and more secretive. Members of Ardeidae fly with their necks retracted, unlike other long-necked birds such as storks, ibises, and spoonbills. Great blue heron, Ardea herodias
