Illustration of Red Crossbill (Loxia curvirostra)

The Red Crossbill has one of the most specialized bills in the bird world — the tips of the upper and lower mandibles cross, acting as a precision tool to pry open conifer cones and extract seeds. It is highly nomadic, following cone crops across the continent with no predictable migration. Several distinct call types ('types') exist that may represent cryptic species with different bill sizes matched to different conifers.

Habitat
Coniferous forests wherever cone crops are abundant
Diet
Conifer seeds, especially spruce, fir, pine, and hemlock
How common
