General

Streaked Shearwater: Large shearwater with scaled, dark gray-brown upperparts and white underparts. White head has variable light to heavy pale brown streaks. Uppertail coverts are sometimes white, forming a pale "horseshoe." Forehead is white. Bill is pale. Legs and feet are pink. Sexes are similar.

Range and Habitat

Streaked Shearwater: Breeds in large numbers on islands of southern Japan. In autumn may be seen in Hawaii and, occasionally, off the coast of California. Pelagic, comes ashore only to breed.

Breeding and Nesting

Streaked Shearwater: One white egg is laid in a burrow. Incubation ranges from 47 to 58 days and is carried out by both parents.

Foraging and Feeding

Streaked Shearwater: Feeds on small fish and squid. Plunge dives in shallow water for food or swoops down to snatch prey from the water surface.

Vocalization

Streaked Shearwater: Silent at sea.

Similar Species

Streaked Shearwater: Cory's Shearwater lacks streaks on head and distinctive, dark- streaked patch on underwing.

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.
