Cardinals nesting habits1/10/2024 ![]() During foraging, young birds give way to adults and females tend to give way to males. You typically see cardinals moving around in pairs during the breeding season, but in fall and winter they can form fairly large flocks of a dozen to several dozen birds. The distinctive crest can be raised and pointed when agitated or lowered and barely visible while resting. Cardinals commonly sing and preen from a high branch of a shrub. Northern Cardinals hop through low branches and forage on or near the ground. Naked except for sparse tufts of grayish down, eyes closed, clumsy. Grayish white, buffy white, or greenish white speckled with pale gray to brown. Cardinals usually don’t use their nests more than once. The nest typically takes 3 to 9 days to build the finished product is 2-3 inches tall, 4 inches across, with an inner diameter of about 3 inches. The cup has four layers: coarse twigs (and sometimes bits of trash) covered in a leafy mat, then lined with grapevine bark and finally grasses, stems, rootlets, and pine needles. She crushes twigs with her beak until they’re pliable, then turns in the nest to bend the twigs around her body and push them into a cup shape with her feet. Males sometimes bring nest material to the female, who does most of the building. ![]() They use many kinds of trees and shrubs, including dogwood, honeysuckle, hawthorn, grape, redcedar, spruce, pines, hemlock, rose bushes, blackberry brambles, elms, sugar maples, and box elders. Nests tend to be wedged into a fork of small branches in a sapling, shrub, or vine tangle, 1-15 feet high and hidden in dense foliage. The pair call back and forth and hold nesting material in their bills as they assess each site. Back to top Nesting Nest PlacementĪ week or two before the female starts building, she starts to visit possible nest sites with the male following along. They also eat beetles, crickets, katydids, leafhoppers, cicadas, flies, centipedes, spiders, butterflies, and moths. Cardinals eat many kinds of birdseed, particularly black oil sunflower seed. Common fruits and seeds include dogwood, wild grape, buckwheat, grasses, sedges, mulberry, hackberry, blackberry, sumac, tulip-tree, and corn. Northern Cardinals eat mainly seeds and fruit, supplementing these with insects (and feeding nestlings mostly insects). Growth of towns and suburbs across eastern North America has helped the cardinal expand its range northward. Cardinals nest in dense foliage and look for conspicuous, fairly high perches for singing. Look for Northern Cardinals in dense shrubby areas such as forest edges, overgrown fields, hedgerows, backyards, marshy thickets, mesquite, regrowing forest, and ornamental landscaping.
