House Finch
The rooftop songster, a streaky finch whose males blush red on the chest and whose ancestors crossed a continent from a pet-shop release.
Least Concern
Haemorhous mexicanus
Overview
The house finch is one of North America's most familiar feeder birds, with males showing variable red on the head, chest, and rump, the colour comes from pigments in their food, so diet affects how vivid they appear. Females are plain brown and streaked.
Native to the western US, house finches were sold illegally as cage birds in New York in the 1940s. When released, they spread eastward and now occupy nearly every corner of the continent, adapting easily to cities, suburbs, and farms.

Field notes
Field scale for the House Finch: length around 12-15 cm; weight 16-27 g. Typical lifespan: 5-11 years in the wild.
When you are scanning habitat, prioritise cities, suburbs, farmland, and desert scrub. Those settings are where a clean look and a usable photo are most likely.
Quick ID anchor: Males show raspberry-red (sometimes orange or yellow) on the head, breast, and rump over a streaky brown body. Females are plain streaky brown with a gently notched tail and no bold head pattern. Confirm with behaviour and habitat before you log the discovery.
Diet
Seeds, buds, and fruit, with heavy use of bird feeders in towns. Nestlings are fed a soft mash of regurgitated plant material and some invertebrates.
Behaviour
Social and vocal; males sing long, warbling songs from rooftops and wires. Often nests in hanging planters, building ledges, and dense shrubs near people.

Interesting facts
- 01
House finches were released in New York in 1940 and spread across North America.
- 02
Male redness depends on diet, carotenoids from berries and seeds deepen the colour.
- 03
Their warbling song can include mimicked snippets of other birds.
Conservation status
House finches are Least Concern and abundant. Populations in eastern states were reduced by a bacterial eye disease in the 1990s but have largely recovered.
