Purple Finch Life History

Habitat

Habitat ForestsIn summer, Purple Finches are primarily birds of moist, cool evergreen forests. You’ll also find them in mixed forests, along wooded streams, and in tree-lined suburbs. In winter they’re more widespread, using forests, shrubby areas, weedy fields, hedgerows, and backyards.Back to top

Food

Food SeedsPurple Finches eat mainly seeds of coniferous trees and elms, tulip poplars, maples, and others. They also eat soft buds, nectar (extracted by biting the bases off flowers), and many berries and fruit, including blackberries, honeysuckle, poison ivy, crabapples, juniper berries, cherries, and apricots. In winter you may see Purple Finches eating seeds of low plants like dandelions, ragweed, and cocklebur. They eat some insects, including aphids, caterpillars, grasshoppers, and beetles.Back to top

Nesting

Nest Placement

Nest TreeLook for Purple Finch nests far out on the limb of a coniferous tree or, particularly to the south of its breeding range, in deciduous trees such as oaks, maples, and cherries. Occasionally nests in shrubs or among vine tangles. Nests can be 2.5 feet up to 60 feet off the ground and are often built under an overhanging branch for shelter.

Nest Description

Nests take 3-8 days to build, with the female doing most or all of the work. She makes the base from twigs, sticks, and roots, then lines the cup with fine grasses and animal hair. The finished nest is about 7 inches wide and 4 inches tall.

Behavior

Behavior Foliage GleanerAggressive Purple Finches show their agitation by leaning toward their opponent, neck stretched out and bill pointed at the other bird. This can intensify to standing upright, opening the beak or pointing it downward at opponent, and sometimes results in actual pecking attacks. During disputes at food sources and in flocks, females usually win out over males. Courting males sing softly while hopping and fluffing feathers in front of the female, often holding a twig or grass stem in the beak. If things go well, the next step is a short flight about one foot straight up, followed by drooping the wings and pointing his beak to the sky. Mating may follow. Back to top

Conservation

Conservation Low ConcernPurple Finch populations decreased by almost 1.5% per year between 1966 and 2014, resulting in a cumulative decline of 52%, according to the North American Breeding Bird Survey. Partners in Flight estimates the global breeding population at 6.4 million with 92% spending part of the year in the U.S., 66% in Canada, and 1% in Mexico. The species rates a 9 out of 20 on the Continental Concern Score. Purple Finch is not on the 2014 State of the Birds Watch List. Populations may suffer in some areas from competition with the recently arrived House Finch.Back to top

Backyard Tips

Purple Finches have large, seed-cracking beaks, and they seem to like black oil sunflower seeds best. A seed preference study determined that they choose thinner sunflower seeds over wider ones. Coniferous trees in your backyard may encourage Purple Finches to visit.
