Moist Woods Ecosystem-Northern Cardinal


Northern Cardinal

Order: Passeriformes

Family:Cardinalidae

Genus:Cardinalis

Species:C. cardinalis


General Characteristics: The Northern Cardinal is a fairly large, long-tailed songbird with a short, very thick bill and a prominent crest. Cardinals often sit with a hunched-over posture and with the tail pointed straight down. Male cardinals are brilliant red all over, with a reddish bill and black face immediately around the bill. Females are pale brown overall with warm reddish tinges in the wings, tail, and crest. They have the same black face and red-orange bill. Northern Cardinals tend to sit low in shrubs and trees or forage on or near the ground, often in pairs. They are common at bird feeders but may be inconspicuous away from them, at least until you learn their loud, metallic chip note. Look for Northern Cardinals in inhabited areas such as backyards, parks, woodlots, and shrubby forest edges. Northern Cardinals nest in dense tangles of shrubs and vines. The song is a loud string of clear down-slurred or two-parted whistles, often speeding up and ending in a slow trill. The songs typically last 2 to 3 seconds. Syllables can sound like the bird is singing cheer, cheer, cheer or birdie, birdie, birdie. Males in particular may sing throughout the year, though the peak of singing is in spring and early summer.

Special Adaptations: Only a few female North American songbirds sing, but the female Northern Cardinal does, and often while sitting on the nest. This may give the male information about when to bring food to the nest. A mated pair shares song phrases, but the female may sing a longer and slightly more complex song than the male.
