Pyrrhuloxia

Northern Cardinal

Cardinalis cardinalis

Also known as: Redbird, Common Cardinal, Red Cardinal, Cardinal

General appearance

The Northern Cardinal averages 8 to 9 inches (20 to 23 cm) in length, equivalent to a Robin. It has a rounded wing shape and tail that can appear notched, rounded, or square-tipped. The bird's most distinguishing feature is its massive pink bill.

Male vs female

The male Northern Cardinal is our only red bird with a crest and is quite striking in appearance. On the other hand, the female is less vibrant, duller in color, encompassing hues of black, brown, gray, green, and tan, yet shares the crest and the distinctively large pink bill.

Juvenile

Juveniles of this species initially have a black bill, differentiating them from the adults. As they mature, their bill turns from black to the characteristic pink, and they inherit the crest from their parents, although their coloration may range from tan to red, depending on their sex.

How to tell the Northern Cardinal from the Pyrrhuloxia

Visual differences

The Northern Cardinal is slightly larger than the Pyrrhuloxia, averaging 8-9 inches. Cardies have a distinctive massive pink bill, while Pyrrhuloxias display a yellow to yellow-orange, stubby, curved bill. Northern Cardinals boast vibrant red plumage with males being fully red and females brownish-tan with hints of red. Pyrrhuloxias are primarily gray and red, with males showing more red, and females are buff with red tinges. Both species share crested heads, but the Pyrrhuloxia's crest is spiky.

Key differences and behavior

The Northern Cardinal and Pyrrhuloxia exhibit distinct behaviors and habitat preferences that help in identification. Cardinals, found in the East and Southwest U.S., favor semi-open areas like woodland edges and city parks. They share songs, with females often singing longer, complex tunes, and males defending territories through song and feeding behavior. They feed on seeds, insects, and berries. Pyrrhuloxias, or "desert cardinals," thrive in arid, dense brush areas of the Southwest, such as mesquite groves. They rely on insects for water, showing resilience in desert climates. Males sing to defend territory and court females by feeding them. Although both species visit feeders for sunflower seeds, Pyrrhuloxias have a penchant for mesquite seeds. Their nesting behaviors are similar, but Pyrrhuloxias prefer thorny shrubs for nest sites, showcasing their adaptability to harsh environments.
