Common Redpoll
Common Redpoll
Acanthis flammea
At a Glance
One of the 'winter finches,' nesting in the Arctic and sometimes invading southern Canada and the northern states. Redpolls are tiny, restless birds, feeding actively on seeds among trees and weeds, fluttering and climbing about acrobatically, their flocks seemingly always on the move. For their small size, they have a remarkable ability to survive cold temperatures; their southward flights are sparked by temporary scarcity of food in the North, not by cold. At bird feeders in winter, redpolls are often remarkably tame.

Behavior
Eggs
4-5, rarely up to 7. Pale green to blue-green, with purplish to reddish brown spots often concentrated at larger end. Incubation is by female only, about 10-11 days. Male feeds female during incubation.
Young
Fed mostly by female; contribution by male varies. Young leave the nest about 12 days after hatching.
Feeding Behavior
Forages very actively in trees, shrubs, weeds, and on the ground. Except when nesting, usually forages in flocks. Has a pouch within throat where it can store some food for up to several hours; this helps the bird in bitterly cold weather, allowing it to feed rapidly in the open and then digest food over a long period while it rests in a sheltered spot.
Diet
Mostly seeds, some insects. Diet for most of year is mostly seeds and other vegetable matter. Feeds on catkins, seeds, and buds of willows, alders, and birches, small conifer seeds, also seeds of many weeds and grasses. Also eats insects, mainly in summer.
Nesting
Males dominate females in winter flocks, but as breeding season approaches, females become dominant and may take the lead in courtship. Does not seem to defend much of a nesting territory; nests of different pairs may be close together. Nest: Usually very well hidden in dense low shrubs, within a few feet of the ground, sometimes in grass clumps or under brushpiles. Nest (probably built by female) is an open cup of fine twigs, grass, moss, lined with feathers (especially ptarmigan feathers), plant down, or animal hair.
