Range and Habitat

Scaup: Winter visitor to the UK & Ireland. A few pairs breed each year. Birds are visible from autumn until spring.

INTERESTING FACTS

  • The Scaup's name may come from its display call of "scaup scaup."
  • In North America, their population has been declining since the 1990's. Biologists and conservationists are not sure of the reasons for decline.
  • Occasionally an older female will have male-like head colour and male patterning on her back, but she still has the typical white face patch of a female.
  • A group of ducks has many collective nouns, including a "brace", "daggle", "flock", "paddling", and a "wadddling" of ducks.

The ventral part of the bird, or the area between the flanks on each side and the crissum and breast. Flight muscles are located between the belly and the breast.
BreastX
The upper front part of a bird.
RumpX
The area between the uppertail coverts and the back of the bird.
VentX
Birds do not have two separate cavities for excrement and reproduction like humans do. In birds, there is one single entrance/exit that suits both functions called the vent, cloaca or anus.
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.
