Common Redpoll

Overview

The Common Redpoll breeds across circumpolar arctic and subarctic regions, in birch and willow scrub at the edge of the tundra. In winter, it can move irregularly, or irrupt, into temperate regions in search of seed crops, sometimes appearing in large numbers at feeders far south of its usual range.

Its small size, streaked plumage, and bright red cap make it a recognizable winter visitor across much of the Northern Hemisphere.

Feather Identification

• Crown: small, bright red patch (the 'poll') on the forehead.
• Chin: black patch just below the bill.
• Underparts: streaked white to buffy, with a pink wash on the breast of breeding males.
• Bill: small, conical, and yellowish, adapted for extracting seeds from catkins.
• Tail: notched, typical of many finches.

The red cap and black chin combination separates redpolls from most other small streaky finches; separating Common Redpoll from Hoary Redpoll relies on more extensive streaking and a slightly larger bill in Common Redpoll.

Plumage Notes

Breeding males show the brightest pink wash on the breast alongside the red cap and black chin. Females lack the pink breast wash, showing more uniform streaking below.

Juveniles lack the red cap initially, acquiring it as they molt into first-winter plumage. A single annual molt follows breeding, with plumage remaining fairly stable through the winter months.

Habitat & Range

Common Redpolls breed across circumpolar arctic and subarctic regions in birch and willow scrub near the tundra edge. In winter, they move south into temperate regions of North America, Europe, and Asia, with the extent of movement varying year to year depending on seed crop abundance.

Irruptive winters can bring large numbers far south of the typical wintering range, followed by years with few or no birds observed in the same areas.

Behavior & Field Notes

Common Redpolls forage in flocks on birch and alder catkins, weed seeds, and at feeders during winter, often appearing tame and approachable.

The nest is built low in arctic scrub. The call is a distinctive dry rattle or trill, often given in flight by flocking birds. The red cap, black chin, and pink-washed breast on males are the most useful features for identification, with careful comparison needed to separate this species from the paler Hoary Redpoll.
