Two-barred Crossbill: Medium-sized crossbill, bright pink to red overall except for black wings with two bold, broad white wing-bars. Belly has dull white center; undertail coverts are white. Tail is black and deeply notched. Female is brown-streaked overall with olive-brown rump. Juvenile is heavily streaked.

Range and Habitat

Two-barred Crossbill: Rare vagrant to the UK & Ireland. Year-round resident in thick evergreen forests in a wide band from the Atlantic coast of North America west across Canada and the northern US, to the Pacific coast of Asia, continuing west across north Asia to eastern Finland. Makes only short-distance moves in search of new food sources in winter, but famously irruptive.

Breeding and Nesting

Two-barred Crossbill: Three to five brown and purple spotted, white to blue green eggs are laid in a nest made of grass, bark, lichens, moss, and hair, and lined with twigs and weeds. Incubation ranges from 12 to 14 days and is carried out by the female.

Vocalisation

Two-barred Crossbill: Vigorous musical warbles and chatters, "sweet, sweet, sweet", on different pitches and often issued during display flight on hovering wings. Call is rapid, harsh repetitive series of "chif-chif-chif" notes and plaintive "peet." Also uses a loud "meep" call, as well as chatter and twittering notes.

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.
