Haemorhous mexicanus

Family: Fringillidae

House Finch (Haemorhous mexicanus) is a common and adaptable songbird found in residential areas, open woodlands, and urban environments across North America. Males show variable red coloration on the head and chest, while females are streaked brown and lack any red tones.

Description

Haemorhous mexicanus is recognized by:

• Size: small songbird, approximately 5–6 in (13–15 cm)
• Male plumage: brown with streaking and red (sometimes orange or yellow) on head, throat, and upper chest
• Female plumage: gray-brown overall with heavy streaking and no red coloration
• Bill: short, conical, adapted for seed feeding
• Tail: moderately long and slightly notched

Color intensity in males varies depending on diet, resulting in a range of hues from pale orange to deep red.

Habitat and Range

Typical habitats include:

• Residential neighborhoods and suburban gardens
• Open woodlands and forest edges
• Urban parks and agricultural areas

Notes may include:

• Common year-round resident in Minnesota
• Frequently observed at feeders, especially those offering sunflower seeds
• Readily nests on buildings, ledges, and ornamental vegetation

Identification

Key features for field diagnosis:

• Male: red coloration concentrated on the face and upper chest, with streaked brown back and flanks
• Female: plain brown with strong streaking, lacking any bold facial pattern
• Voice: a lively, warbling song with varied notes and phrases
• Structure: compact body with a relatively long tail and small head

Often confused with Purple Finch, but House Finch typically shows more streaking and less extensive red.

Behavior and Ecology

• Social and often observed in small groups or loose flocks
• Males sing persistently during breeding season, often from exposed perches
• Nests are shallow cups built in sheltered locations, including human structures
• Diet consists primarily of seeds, buds, and fruits, with occasional insects

House Finches are highly adaptable and thrive in close association with human-altered environments.

Notes

• Common visitor to backyard feeders throughout the year
• Male coloration varies widely depending on diet
• Frequently seen perched on wires, fences, and feeder structures
• Social interactions often involve subtle displacement and repositioning rather than overt aggression
