Description of the Pine Siskin


The Pine Siskin is a goldfinch-sized finch with streaked brown upperparts, whitish underparts with heavy brown streaking, varying amounts of yellow in the wings, and a thin, pointed bill that is slightly longer and thinner that that of goldfinches.

Males have more yellow in the wings, including a broad yellow wing-bar.

Seasonal change in appearance



Similar to adult females.


Pine Siskins are found in coniferous, mixed, and deciduous woodlands.


Pine Siskins primarily eat seeds, but also some insects.


Pine Siskins forage in trees and shrubs, and usually occur in flocks outside of the breeding season.


Pine Siskins occur across most of North America, though they breed in the western U.S. and southern Canada and only occur during winter in the rest of the U.S. The population has declined in recent years.

Wing Shape

The shape of a bird's wing is often an indication of its habits and behavior. Fast flying birds have long, pointed wings. Soaring birds have long, broad wings. Different songbirds will have a slightly different wing shape. Some species look so much alike (Empidonax flycatchers) that scientists sometimes use the length of specific feathers to confirm a species' identification.

Fun Facts

Like many northern finches, Pine Siskins are irruptive in winter occurrence and are much more common in some years than in others.

Pine Siskins often visit bird feeders with flocks of goldfinches, both of which are fond of sunflower and thistle seeds.

Pine Siskins occasionally stay at a wintering location to breed if food supplies are plentiful, even though it may be far from the normal breeding range of the species.


The song is a rapid sequence of low notes. Various buzzy or sharp calls are also given.


Attract with suet or peanut butter.


The nest is a cup of twigs, grass, and bark and is lined with softer materials. It is usually placed on an outer branch of a conifer tree.

Usually lay 3-4 eggs.


Greenish-blue with darker markings.

Incubation and fledging:
The young hatch at about 13 days, and leave the nest in another 14-15 days, though continuing to associate with the adults for some time.
