They usually nest in cavities in trees close to water, although they will take advantage of nesting boxes in wetland locations. Other species may compete with them for nesting cavities, such as birds of prey , as well as mammals such as grey squirrels, and these animals may also occupy nest boxes meant for wood ducks.
Nest boxes come into effect when the species is limited and dying out due to the following predators: cats, raccoons, opossums, and select birds of prey such as the Cooper's hawk. Ants, bees, earwigs, and wasps can crawl into the nesting boxes and damage the newborns. [5] Western bluebirds are among the birds that nest in cavities, or
Violet-green swallows are secondary cavity nesters, meaning they typically nest in natural holes or previously occupied nests. [15] [16] Some breeding pairs will even go as far as usurping nests from other species.

Kestrels occasionally nest in holes created by large woodpeckers, [50] or use the abandoned nests of other birds, such as red-tailed hawks, merlins, and crows. [51] They have been recorded nesting on cliff ledges and building tops, as well as in abandoned cavities in cactuses. [52] [40] American kestrels also commonly utilize nesting boxes. [53]
