Anatomy and morphology

Distribution and habitat

The breeding habitat is open areas in western North America. The increased presence of trees throughout the Great Plains during the past century due to fire suppression and tree planting facilitated the range expansion of the western kingbird, as well as range expansions of many other species of birds.

Behavior

s. They will attack humans, livestock, and pets when they think their young are in danger. Kingbirds make a sturdy cup nest in a tree or shrub, sometimes on top of a pole or other man-made structure. Three to five white, creamy, or pinkish eggs with heavy blotches of brown, black, or lavender are laid and incubated for 12 to 14 days. Due to the small size of the nest, and the chicks' rapid rate of growth, most of them are pushed out of the nest, due to overcrowding, before they are fully feathered and able to fly. They wait on an open perch and fly out to catch insects such as bees, robber flies, winged ants, grasshoppers, and spiders. They are also known to eat berries, buckthorn/sumac, and poison ivy seeds.
