Cardinalis cardinalis
Northern cardinals are medium-sized songbirds. Males are bright red except for a black mask on their face. Females are light brown or light greenish-brown, with reddish highlights and do not have a black mask (but parts of their face may be dark). Both males and females have thick, orange-red, cone-shaped bills, a long tail, and a distinctive crest of feathers on the top of their heads. Males are slightly larger than females. Males are 22.2 to 23.5 cm long whereas females are 20.9 to 21.6 cm long. The average weight of adult cardinals is 42 to 48 g. Immature cardinals are similar in appearance to females, but have a gray-black rather than orange-red bill.
Northern cardinals have a preference for the edges of woods, hedgerows, and vegetation around houses. This may be partially responsible for the increase in their population since the early 1800's. Cardinals also benefit from the large numbers of humans who feed them and other seed-eating birds with backyard bird feeders. Cardinals prefer to build their nests in dense thickets.
This male Northern Cardinal was perched in a pine tree in my front yard.
