White-winged Scoter

Melanitta deglandi

Its scientific name calls it a 'black duck,' and it mostly is: the white is just a patch on each wing. The second half honors Côme-Damien Degland, a French doctor and bird expert.

Melanitta joins the Greek melas, 'black,' and netta, 'duck'; deglandi honors Degland, a 19th-century French physician who wrote about Europe's birds.
