Hoary Redpoll

Overview

The Hoary Redpoll breeds in the High Arctic, generally farther north than the Common Redpoll, in sparse tundra scrub. Its pale, frosty overall appearance reflects its extreme northern range, and it occasionally appears farther south in winter, sometimes among flocks of Common Redpolls.

Distinguishing the two redpoll species requires careful attention to subtle plumage differences.

Feather Identification

• Crown: small red cap similar to Common Redpoll, but the surrounding plumage is notably paler.
• Underparts: whiter overall, with reduced streaking on the flanks and rump compared with Common Redpoll.
• Rump: often appears largely white or very lightly streaked, a key difference from Common Redpoll.
• Bill: appears slightly shorter and stubbier than in Common Redpoll.

The overall paler, frostier tone, reduced flank and rump streaking, and stubbier bill are the main features separating Hoary Redpoll from the closely similar Common Redpoll.

Plumage Notes

Breeding males show a faint pink wash on the breast, generally less extensive than in Common Redpoll. Females are paler still, with minimal streaking below.

Juveniles lack the red cap initially, acquiring it during the first molt into immature plumage. A single annual molt follows breeding, after which plumage remains pale and lightly marked through the winter.

Habitat & Range

Hoary Redpolls breed in the High Arctic, including northern parts of North America, Greenland, and Eurasia, in sparse tundra scrub often farther north than Common Redpoll territory. In winter, some birds move south, occasionally mixing with Common Redpoll flocks in subarctic and temperate regions.

Its remote breeding range makes it a less frequently encountered species than the more widespread Common Redpoll.

Behavior & Field Notes

Hoary Redpolls forage in flocks on seeds from tundra scrub and, in winter, at feeders alongside Common Redpolls, showing similar tame behavior.

The nest is built low in sparse arctic scrub. The call resembles that of the Common Redpoll, a dry rattling trill. Careful comparison of overall paleness, rump streaking, and bill shape is needed to confidently separate this species from Common Redpoll where the two occur together.
