Diagnosis. This average sized finch (15cm) is highly colorful, with its bright red head, bib and rear. The chest is distinct from the barred underbelly, and the head is broken by a brown patch behind the eye and a slight brown patch on the crown of the head. The females are markedly different from the colorful male, showing no red; their brown bodies are streaked all over and carry no real distinguishing features.

Natural History. House Finches are highly social, they live and breed as a flock. They are a highly fecund species, with the female having up to six broods per season. Laying 2-6 eggs at a time, and with a low incubation and nesting period (12-19 days each) the species has rapidly grown and spread since the 1940’s.

Distribution

Within Kansas: Found in all counties of Kansas, the House Finch has established breeding populations in all but a few western counties.

Within North America: The House Finch can be readily found in all parts of lower North America. Having originated in the western U.S., and being introduced into the east in the 1940’s, the two populations have exploded and their ranges have met in the middle.
