The Costa's Hummingbird has a large range, estimated globally at 130,000 square kilometers. It is native to the Mexico and the United States and prefers forest or shrubland ecosystems, though it has been known to reside in degraded former forests. The global population of this bird has not been quantified, but it does not appear to meet population decline criteria that would necessitate inclusion on the IUCN Red List. The current evaluation status of the Crimson-collared Grosbeak is Least Concern.
Crimson-collared Grosbeak: Large finch with blood-red body, brown-red back, black hood, bib, huge conical bill, and dark wings. Forages in brushy woodland. Feeds on insects, larvae, seeds, fruits, berries. Short flights, alternates rapid wing beats with wings pulled briefly to sides.

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.
