The northern ﬂicker averages about 12 to 14 inches in length. It has a large, white-feathered, rump patch that can be seen when this bird ﬂies. Its back feathers are brown with dark bars. There is a black-feathered patch on the upper chest, and a red-feathered patch on the back of the head. The male has a black mark below each eye.
The northern ﬂicker is a common migrant, summer resident and winter resident statewide in Illinois. Those ﬂickers that migrate from Illinois in the fall overwinter in the southern United States. Migration occurs during the day and at night. Spring migrants begin arriving in Illinois in March. Nesting occurs from April through May. The nest may be placed in trees scattered in grasslands, forest edges or residential areas. A cavity is excavated by the male and female over a one- to two-week period in a live tree, dead tree, snag, fence post or on the side of a building. This bird will use a nest box if one is available. The nest is built from two to 60 feet above the ground. Five to 12 white eggs are laid by the female. Eggs are incubated by the male and female during the day, and only by the male at night, over an 11- to 12-day period. Fall migration begins in July. The northern ﬂicker lives in cornﬁelds, shrubs, open forests, orchards, pastures and towns. Its song is a repeated “wick wick wick” while the call notes are “klee-yer” and “ﬂick-a.” This bird spends much time on the ground, searching for ants. It will also eat beetles, blackberries, poison ivy berries and wild black cherries.
