The Red Crossbill is a stocky, nomadic finch whose crossed mandibles are specialized for opening conifer cones. The bill tips spread the cone scales while the tongue removes the seed. Flocks move widely in response to irregular cone crops and may breed in any season when food is abundant. Adult males are usually brick red, females yellow-green and young birds strongly streaked. Several call types differ in voice and bill size and may specialize on different conifers.
