General

Long-tailed Duck: Small diving duck with black upperparts, head, neck, breast, and wings; back shows black and brown mottling; flanks, belly and undertail coverts are white. Tail is black with long, pintail-like central feathers that are often submersed when swimming. Mask is pale gray and bill is black with a dark pink saddle. Female is duller, lacks long tail, and has gray bill. Winter male retains the long tail feathers and has white crown, neck, back, flanks and belly, black breast, lower back and neck spot, gray mask, and black wings with white shoulder blades visible in flight. Winter female is duller, has black cap, white face, shorter tail, and gray bill. Juvenile resembles winter female but is grayer overall.

Range and Habitat

Long-tailed Duck: Breeds from Alaska east across most of northern Canada. Spends winters along the Pacific coast from the Bering Sea south to California; from Greenland, eastern North America, and Labrador south, including the Great Lakes, to South Carolina. Preferred habitats include a variety of coastal waters, mostly deeper waters of straits, bays, harbors, channels, and fiords. Other habitats include estuaries, offshore waters, mudflats, and rarely, large lakes and rivers.

Breeding and Nesting

Long-tailed Duck: Five to eleven olive buff, olive gray, or green yellow eggs are laid in a hollow of grass and down hidden in low vegetation or among rocks. Incubation ranges from 23 to 25 days and is carried out by the female. Young start to fly at 35 to 40 days.

Foraging and Feeding

Long-tailed Duck: Feeds on aquatic plants, shrimp, and insects; dives from the surface to forage underwater.

Vocalization

Long-tailed Duck: Utters a melodious and barking, "ow-owdle-ow, ow-owdle-ow" when breeding. Noisy in all seasons; most garrulous of all North American ducks.

4 and 6 letter alpha codesX

The four letter common name alpha code is is derived from the first two letters of the common first name and the first two letters of common last name. The six letter species name alpha code is derived from the first three letters of the scientific name (genus) and the first three letters of the scientific name (species). See (1) below for the rules used to create the codes..

Four-letter (for English common names) and six-letter (for scientific names) species alpha codes were developed by Pyle and DeSante (2003, North American Bird-Bander 28:64-79) to reflect A.O.U. taxonomy and nomenclature (A.O.U. 1998) as modified by Supplements 42 (Auk 117:847-858, 2000) and 43 (Auk 119:897-906, 2002). The list has been updated by Pyle and DeSante to reflect changes reported by the A.O.U from 2003 through 2006.

ITIS CodesX

The Integrated Taxonomic Information System (ITIS) was established in the mid-1990�s as a cooperative project among several federal agencies to improve and expand upon taxonomic data (known as the NODC Taxonomic Code) maintained by the National Oceanographic Data Center (NODC), National Oceanic and Atmospheric Administration (NOAA).

To find the ITIS page for a bird species go to the ITIS web site advanced search and report page at http://www.itis.gov/advanced_search.html. You can enter the TSN or the common name of the bird. It will return the ITIS page for that bird. Another way to obtain the ITIS page is to use the Google search engine. Enter the string ITIS followed by the taxonomic ID, for example "ITIS 178041" will return the page for the Allen's Hummingbird.
