Guide to Boreal Birds
Largest of the northern finches, the Pine Grosbeak is less common than the Pine Siskin or the redpolls. When these birds do appear their preference for the seeds and fruit of trees such as mountain ash and cedar makes them more conspicuous than their smaller relatives. They are very tame and slow moving, allowing close approach. During snowy winters these grosbeaks can be located in scattered open forests by the feeble calls that keep the flock together. They settle in a tree and feed, snapping off buds or seeking the pits in fruit, until sated or disturbed. When food is scarce, they may descend from mountains into woods at sea level.
