General

Arctic Warbler: Medium-sized, active warbler with stout bill, olive-green back, olive-brown sides, and white throat and belly. Dark eye-lines contrast with pale yellow eyebrows curving upward behind eyes. Wings have faint pale bar on tips of greater coverts. Tail is square. Sexes are similar.

Range and Habitat

Arctic Warbler: Occurs in Fennoscandia and northern Asia, and is also established in North America, where they breed in Alaska. They migrate to Southeast Asia for the winter, having the longest migration route of any Old World insectivorous bird. Preferred habitats include birch woods, willow thickets, mixed coniferous-deciduous open forests, and grassy tundra. Rare vagrant to the UK.

Breeding and Nesting

Arctic Warbler: Five to seven white eggs, sometimes spotted with red-brown, are laid in a sphere-shaped nest built by the female on the ground, hidden in thickets of willow and birch. Female incubates eggs for about 13 days.

Foraging and Feeding

Arctic Warbler: Diet includes insects and other small invertebrates.

Vocalisation

Arctic Warbler: Song is a long, loud series of toneless, buzzing notes. Call is a buzzing "dzik."

Similar Species

Arctic Warbler: Chiffchaff has a light brown eyebrow. Willow Warbler has a dark eye line. Garden Warbler has no eyebrow. All three are very common.

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.
