Sulphur-bellied Flycatcher
Sulphur-bellied Flycatcher
Myiodynastes luteiventris
At a Glance
One of the last spring migrants to arrive in southern Arizona, the Sulphur-bellied Flycatcher brings an unmistakable touch of the tropics. Colorful, strongly patterned, and noisy, it seems far more exotic than most of the drab North American flycatchers. Its shrill calls, sounding like rusty hinges or squeaky rubber toys, are typical sounds of summer among the sycamores in lower canyons near the Mexican border.

Habitat
Sycamore-walnut canyons. In our area, found mainly in lower parts of canyons in the mountains, where tall sycamores and other trees grow along streams through pine-oak forest. Also locally in sycamores and cottonwoods along streams at lower elevations. In the tropics, found in open woods, groves, and forest edges.

Behavior
Eggs
3-4. White to pale buff, heavily spotted with reddish brown. Incubation is by female only, 15-16 days.
Young
Both parents bring food to nestlings. Age of young at first flight about 16-18 days.
Feeding Behavior
Forages by watching from a perch, then flying out to capture insects. Usually forages fairly high, perching on a twig within the shady upper levels of a tree. Flies out and hovers while taking an insect from foliage or branches, or may catch insects in mid-air.
Diet
Mostly insects. Diet is not known in detail, but feeds mainly on insects, probably including large caterpillars, beetles, katydids, and others. Also eats some small fruits and berries.
Nesting
In courtship, male and female perch close together, shaking their heads back and forth and calling in duet. Very aggressive during the nesting season, pairs of Sulphur-bellies may compete for choice cavities with other hole-nesting birds, even Elegant Trogons. Nests mainly in mid-summer in Arizona, most eggs probably hatching in July. Nest site in Arizona is usually in large natural cavity of sycamore, 20-50' above the ground. Female builds nest. If cavity is deep, she fills it most of the way with twigs and bark strips, then builds nest on top of this foundation, mostly of fine leaf stems and pine needles.
Conservation
Conservation Status
In its limited range in the United States, numbers seem stable or possibly increasing.
