Cassin's Finch -- South Dakota Birds

Cassin's Finch

Carpodacus cassinii

The Cassin's Finch is very similar to the more familiar Purple Finch, but is slightly larger with a larger bill and subtle plumage variations.  While Purple Finches can more often be found in lowlands and in suburban settings, the Cassin's Finch is normally a bird of mountainous conifer forests.  They may occasionally stage irruptive migrations to lowlands, and rarely may move out onto the Great Plains in small numbers.

Habitat: They primarily breed in mountainous conifer forests of western North America, sometimes being found all the way up to the tree line.  They are also most often found in conifer forests during the winter, although many times at lower elevations.

Diet: Primarily feeds on seeds, tree buds, berries, and other small fruits.  They are very fond of the seeds of conifer trees.  When available, they will also take insects.

Nesting: June and July

Breeding Map: Breeding Bird Survey map

Song: A long rich musical warbling that can be quite variable.  They also have a variety of calls. 

Migrations: They are not strictly migratory, but are somewhat nomadic.  Birds do irregularly move into lower elevation areas during the winter, and those at the northern end of the range may move southward a short distance for the winter.  

Feeders: Various seeds 

Similar Species: House Finch, Purple Finch

Status: Numbers appear to be stable
