INTERESTING FACTS

  • The Pomarine Skua was first described in 1815 by Coenraad Jacob Temminck, Dutch aristocrat and zoologist.
  • Like other skuas, it will fly at the head of a human or any other intruder approaching its nest.
  • Successful reproduction occurs only in one of every three or four years in a typical lemming cycle, and only in areas where lemming populations reach high concentrations.
  • A group of skuas are collectively known as a "shishkab" of skuas.

BIRDS AND BIRDING

.
UnderpartsX

Belly, undertail coverts, chest, flanks, and foreneck.

UpperpartsX
Back, rump, hindneck, wings, and crown.
BreastX
The upper front part of a bird.
CapX
The area on top of the head of the bird.
FaceX
The front part of the head consisting of the bill, eyes, cheeks and chin.
NapeX
Also called the hindneck or collar, it is the back of the neck where the head joins the body.
PrimariesX
The primaries are the flight feathers specialized for flight. They are attached to the "hand" equivalent part of the wing.
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.
PelagicX
The pelagic is a type of bird whose habitat is on the open ocean rather than in a coastal region or on inland bodies of water (lakes, rivers). An example of a pelagic bird is the blacklegged kittiwake.
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.
