The migration of this bird is variable; in some winters, it may wander as far south as the southern U.S.
The range of this bird has expanded far to the east in historical times, possibly due to plantings of Manitoba maples and other maples and shrubs around farms and the availability of bird feeders in winter.
There are 3 subspecies:
- H. v. brooksi:
- H. v. vespertinus:
- East-central Canada (Alberta to New England); winters to south-eastern US
- H. v. montanus:
The breeding habitat is coniferous and mixed forest.
These birds forage in trees and bushes, sometimes on the ground. They mainly eat seeds, berries and insects. Outside of the nesting season, they often feed in flocks. Sometimes, they will swallow fine gravel for the salts.
The nest is built on a horizontal branch or in a fork.
