The American Three-toed Woodpecker has a large range that reaches across North America. It can be found reaching into the Rock Mountains. The range of this species is estimated to be up to 10 million square kilometers. The American three-toed Woodpecker does tend to prefer conifer forests. The population of this species is fairly large, reaching more than 800,000 individual birds. Although there has been concern that logging as well as other forestry practices would lead to the decline of this bird's population, at this time it still has an evaluation rating of Least Concern.
American Three-toed Woodpecker: Medium woodpecker with black-and-white barred upperparts, black head, yellow crown, white eye-line, throat, breast, and belly, and diagonally barred white flanks. Wings are black with white spots; rump is black; tail is black with white outer feathers.
American Three-toed Woodpecker: Breeds from northern Alaska, across Canada's boreal regions, through northern Saskatchewan, to north-central Labrador and Newfoundland; also in Eurasia, south of the tree line in Scandinavia and Siberia.

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.
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.
