The red crossbill

This bird climbs up branches much like a parrot would, using its crossbill. In terms of plumage, the male wears a brick red colour with brown wings and a brown tail. The female has olive plumage along her back and a yellow breast. This bird feeds primarily on conifer seeds. Food is also an important guide for this species behaviour; should food be lacking, it may suddenly leave its habitat for a more suitable environment. This mountain bird nests in the middle of winter, despite the harshness of the climate, to adapt to the period during which spruces start producing seeds.
