  Mating Behavior

Northern cardinal chicks in their nest.

Male cardinals, with red body feathers as opposed to the tan body feathers of females, have been known to show courtship behaviors, like turning and twisting their bodies while a female cardinal is present.

Northern cardinals are monogamous - one male mates with one female. However, they often choose a different mate each breeding season.

Northern cardinals begin forming breeding pairs in early spring. The male tries to attract a mate by performing courtship displays that show off his crest and his bright red feathers. He will raise his crest and sway side to side while singing softly. Once he finds a female that may be interested, the male feeds the female to show that he would make a good provider for young cardinals.

  Care For Young

Both parents feed nestlings. Young leave nest about 9-11 days after hatching. Male may feed fledglings while female begins next nesting attempt. Norther cardinals have 2-3 broods per year, rarely 4.

Least concern.
