Common Redpoll 2

This year has not been a banner winter for Common Redpolls in Northfield. I banded Common Redpolls on 18 February 2016 and again on 11 March. The March flock contained a few bright red birds. Male redpolls usually take two years to become this color. In their first year, they are much duller, and are not separable from females, which can sport some red.
