Thick-billed Kingbird
At a Glance
Brash and noisy, the Thick-billed Kingbird perches high in streamside sycamores, fluttering its wings as it gives voice to incredibly loud metallic calls that echo through the canyons. This big tropical flycatcher is a recent immigrant to our area, first found in 1958 in Guadalupe Canyon, on the Arizona-New Mexico border. It has since become more widespread as a summering bird north of Mexico, but it is still found mainly at a few Arizona sites.

Behavior
Eggs
3-4. Whitish, blotched with brown. Details of incubation not well known.
Young
Both parents bring food for young in nest. Development of young and age at first flight not well known.
Feeding Behavior
Forages by watching from a perch and flying out to capture insects, returning to perch to eat them. Captures most prey in mid-air, often in long, swooping flights. Usually hunts from high perches near tops of trees, but will forage low, especially in cool weather.
Diet
Insects. Diet is not well known, but probably is mostly or entirely insects. Large bill size suggests the ability to feed on very large insects; has been seen eating large beetles, cicadas, and others.
Nesting
Breeding behavior is not well known. Aggressive in defense of nesting territory, attacking larger birds that come near nest. Both members of mated pairs often perch close together, quivering wings and calling loudly. Nest site is usually high in tall tree (in Arizona, typically in sycamore, sometimes in cottonwood), 50-80' above the ground. Nest is a large but loosely built open cup of twigs, grasses, weeds, leaves, plant down. Nest has a ragged look, with twigs sticking out in all directions; from below, eggs may be visible through bottom of nest.
Conservation
Conservation Status
Has gradually increased in limited range in United States since first arrival in 1950s. Status of Mexican populations not well known.
