Nest Sites and Shelter Nests are built 15 to 60 feet above ground in tall coniferous or deciduous trees. Nests are 1Â½ to 2 feet in diameter, and solidly built in the crotch of a limb or near the tree trunk.In areas that lack tall trees, nests may be placed lower in hedgerows or shrubbery.In urban areas, crows may nest on window ledges or the sides of buildings.hooting is not an effective way to manage crow populations overall. The number of birds that can be killed by shooting is small relative to the size of the flock. However, shooting may be helpful where only a few birds are present, and in supplementing or reinforcing other dispersal techniques.
