Northern Cardinal (Cardinalis cardinalis)
The northern cardinal (Cardinalis cardinalis) is a North American bird in the genus Cardinalis; it is also known colloquially as the redbird or common cardinal. It can be found in southern Canada, through the eastern United States from Maine to Texas and south through Mexico. It is found in woodlands, gardens, shrublands, and swamps.
The northern cardinal is a mid-sized songbird with a body length of 21–23 cm (8.3–9.1 in). It has a distinctive crest on the head and a mask on the face which is black in the male and gray in the female. The male is a vibrant red, while the female is a dull reddish olive. The northern cardinal is mainly granivorous, but also feeds on insects and fruit. The male behaves territorially, marking out his territory with song. During courtship, the male feeds seed to the female beak-to-beak. A clutch of three to four eggs is laid, and two to four clutches are produced each year. It was once prized as a pet, but its sale as a cage bird was banned in the United States by the Migratory Bird Treaty Act of 1918.
The northern cardinal is a mid-sized songbird with a body length of 21–23.5 cm (8.3–9.3 in) and a wingspan of 25–31 cm (9.8–12.2 in). The adult weighs from 33.6–65 g (1.19–2.29 oz), with an average 44.8 g (1.58 oz). The male averages slightly larger than the female. The adult male is a brilliant crimson red color with a black face mask over the eyes, extending to the upper chest.
The color becomes duller and darker on the back and wings. The female is fawn, with mostly grayish-brown tones and a slight reddish tint on the wings, the crest, and the tail feathers.[11] The face mask of the female is gray to black and is less defined than that of the male. Both sexes possess prominent raised crests and bright coral-colored beaks.
The beak is cone-shaped and strong. Young birds, both male and female, show coloring similar to the adult female until the fall, when they molt and grow adult feathers. They are brown above and red-brown below, with brick-colored crest, forehead, wings, and tail. The legs and feet are a dark pink-brown. The iris of the eye is brown. The plumage color of the males is produced from carotenoid pigments in the diet. Coloration is produced from both red pigments and yellow carotenoid pigments.
Northern cardinal males possess the ability to metabolize carotenoid pigments to create plumage pigmentation of a color different from the ingested pigment. When fed only yellow pigments, males become a pale red color, rather than a yellow.
However, there are rare "yellow morph" cardinals, where all feathers (except for black face mask) and beak are a moderate yellow color. During the winter months, both male and female will fluff up their down feathers in order to trap warm air next to their body and keeping cold air from reaching their body. The down feathers are small and hairlike at the base of each flight feather. The legs and feet of almost all birds are thin and lack feathers, and so are vulnerable to rapid heat loss.Therefore, many take turns tucking one leg at a time into their body to keep them warm while still using the other to stand.
