Common Redpoll

Common Redpolls are Abundant during irruptive year with birch catkins mainly from November-March very rare on non irruptive years during those months.

Habitat

Redpolls are Arctic and sub-Arctic breeders, and Common Redpolls typically breed in open coniferous forests and shrubby birch and alder thickets. During winter they inhabit various kinds of semi-open country, including woodland edges and brushy or weedy fields. They can often be found in birch, alder, or willow patches.

Behavior

Busy and acrobatic, Common Redpolls forage in flocks along hedgerows or in catkin-bearing trees. They are well adapted to feeding at the very tips of small branches, hanging upside-down, and using their feet to hold food items. They also forage on the ground, especially in winter, and move in rolling waves across ground-feeding areas. They have pouches in their throats that allow them to gather large amounts of food quickly, and then retreat to a safe place to process the food. In winter, they will drop from a tree into deep snow and make a tunnel about a foot long to a roosting chamber. Like many finches, they have an undulating flight pattern. They are quite vocal, making constant contact calls within their flocks, and are often located by their flight calls.
