White-winged Crossbill

Overview

The White-winged Crossbill inhabits boreal coniferous forest across the Northern Hemisphere, specializing on spruce cones in particular. Like other crossbills, its crossed bill tips are adapted for extracting conifer seeds, and its movements are closely tied to cone crop abundance.

Its bold white wing bars make it one of the easier crossbills to identify at a glance.

Feather Identification

• Bill: crossed at the tip, shared with all crossbill species.
• Wings: black with two broad white wing bars, the standout feature of this species.
• Male body: pink-red overall, generally brighter and pinker than the brick-red of Red Crossbill.
• Female body: yellowish-olive, also showing the white wing bars.

The bold white wing bars against black wings are the clearest way to separate this species from the plain-winged Red Crossbill.

Plumage Notes

Adult males show a bright pink-red body contrasting with black-and-white wings. Females are yellowish-olive with the same white wing bar pattern.

Immature birds show more streaked, duller plumage before acquiring adult coloration. A single annual molt follows breeding, though as with other crossbills, breeding timing can shift depending on cone crop availability.

Habitat & Range

This species is found in boreal spruce forest across northern North America and Eurasia, tracking spruce cone crops in particular, though it also uses other conifers. Its distribution is nomadic and irruptive, shifting in response to seed availability from year to year.

In years of poor spruce cone production, birds may move well south of typical range in search of food.

Behavior & Field Notes

White-winged Crossbills forage in spruce and other conifer canopies, using their crossed bill to extract seeds from cones, often feeding in flocks.

The nest is built in conifer branches, with breeding timed to coincide with cone seed availability rather than a fixed calendar season. The call is a distinctive dry trill, different in tone from the Red Crossbill's call. The bold white wing bars remain the most reliable feature for quick identification against the plain-winged Red Crossbill.
