Grey-crowned Rosy-Finch

Overview

The Grey-crowned Rosy-Finch breeds at high elevations across western North America, favoring alpine tundra, rocky slopes, and cliffs above the treeline. Its plumage combines a brownish body with a distinctive grey patch on the back of the crown and rosy-pink feathering across the wings and belly.

This species is closely related to several other rosy-finches found in similar high-altitude habitats, and separating them typically relies on subtle differences in head pattern and the extent of grey versus brown coloring.

Feather Identification

• Body feathers: overall dark brown, deepest on the back and chest.
• Head feathers: black forehead and forecrown, with a contrasting grey patch on the hindcrown and nape.
• Wing and belly feathers: washed with rosy-pink, particularly noticeable in flight.
• Distinguishing from similar species: the grey crown patch combined with a black forecrown separates this species from the Black Rosy-Finch, which lacks the brown body tone, and from the Brown-capped Rosy-Finch, which lacks grey on the head entirely.

Plumage Details

Adults show a dark brown body with a black forehead and forecrown, a contrasting pale grey patch across the hindcrown and nape, and rosy-pink feathering on the wings, rump, and belly. Sexes are similar, with females generally slightly duller. Non-breeding and juvenile birds show reduced pink tones and a less defined head pattern.

Habitat & Range

Grey-crowned Rosy-Finches breed on alpine tundra, rocky slopes, and cliffs above the treeline across parts of western North America, including Alaska and the Rocky Mountains. They typically move to lower elevations or nearby lowlands during winter rather than undertaking long-distance migration.

Behavior & Field Notes

This species feeds on seeds and insects gathered from alpine vegetation, rocky ground, and even snowfields at high elevation. It often forms flocks outside the breeding season, sometimes mixing with other rosy-finch species. Nests are built in rock crevices or cliff ledges. The grey hindcrown patch combined with a black forecrown is the key feature separating this species from its close relatives among the rosy-finches.
