Translations

Extensive Definition

Mergus is the genus of typical mergansers, ducks in the seaduck subfamily (Merginae).
Although they are seaducks, most of the mergansers prefer riverine habitats, only Red-breasted Merganser being common on the sea. These large fish-eaters have serrated edges to their bills to help them grip their prey. Along with the Smew and Hooded Merganser, they are therefore often known as "sawbills".

Species

Fossil species that have been described are Mergus miscellus from the Middle Miocene Calvert Formation (c. 14 mya, Barstovian) of Virginia, USA and Mergus connectens (Middle Pleistocene of C Europe or somewhere between 800.000 and 125.000 years ago). An undescribed fossil merganser is documented from the Middle Miocene Sajóvölgyi Formation (Late Badenian, 13-12 mya) of Mátraszõlõs, Hungary (Gál et al. 1998-99).
The Hooded Merganser, often termed Mergus cucullatus, is phylogentically not of the Mergus genus.
