Cardinal eggs6/26/2023 ![]() Most are 4-5 feet off the ground, though. Nests may be built as low as 2 feet off the ground, up to 12 feet high. You may encourage cardinals to nest in your yard if you have such dense shrubby plants for them to hide away their nests. Thick vines such as honeysuckle, rose bushes, or young conifer trees are common plants in which cardinals build their nests. The nest is usually built in the fork of a branch of small tree or dense bush. The male may bring some nest material to her, though. The female Northern Cardinal does most of the nest building. Sometimes the male performs a short hop-flight toward his mate, flying slowly and singing with crest raised and plumage fluffed fully. A similar behavior includes raising one wing, lowering the crest and swaying back and forth. Other courtship behaviors include raising one wing and the head crest. Since the bills touch briefly, this has been called a kiss. Some courtship activities include the male feeding seeds to his mate. The female cardinal also sings from the nest. Sometimes the male and female of the pair sings together. They may return every morning to attack the reflection they couldn't vanquish the day before.įemale Cardinals also sing. In the past they attacked reflections in car hub caps, though car wheel designs have changed in recent years. You may see them battling their reflections in windows and external car mirrors. The males are so aggressive that they even attack their own reflections. Fights between male cardinals on adjacent territories are common. They defend their territories vigorously from other males. It sounds to some people like whoit-whoit-whoit, birdy-birdy, cheer-cheer, or other similar notes in varied combinations. The song is made of loud repeated clear single or doubled whistles. All are recognizable, though, as belonging to the cardinal. Songs thus vary across the range of the species. Songs are learned by young birds from the male parent as well as other birds singing locally during the previous breeding season. Male Northern Cardinals start singing more frequently in late winter, declaring their territory from a tall open perch. Then the male returns to help again with the new nestlings and fledglings. She builds a new nest and lays another clutch of eggs. The female, however, goes right back to work. After the young fledge the male takes care of them for a couple of weeks until they are on their own. The female builds the nest and incubates the eggs. Singing may occur year-round in more southerly locations. Males start singing in mid-February in the north part of their range. Otherwise, courtship begins in the early spring for those selecting new mates. Pair bonds are usually strengthened through the winter for those birds who retain the same mate. Cardinals raise from one to four broods each year, though usually two to three at most. The nesting season for Northern Cardinals in the United States runs from March to August.
