Rose-throated Becard
Rose-throated Becard
Pachyramphus aglaiae
At a Glance
This tropical bird barely extends north of the Mexican border in summer. In our area it occurs regularly only along a few streams in southern Arizona. It is also found in southern Texas, especially in winter. Quiet and inconspicuous, it is easily overlooked as it perches high within the canopy of the trees, occasionally fluttering out to pick an insect from the foliage. Its massive, football-shaped nest, swinging at the end of a dangling branch, is often the first clue that becards are present.

Behavior
Eggs
4-6. Whitish to buff, heavily blotched with brown. Incubation is by female; incubation period not well known.
Young
Both parents bring food for nestlings. Young leave nest about 3 weeks after hatching.
Feeding Behavior
Forages mostly by watching from a perch, then making short flights out to capture insects, returning to perch to eat them. Takes most insects from foliage while hovering briefly; also catches some in mid-air. Does much of its foraging within the shady canopy of tall trees.
Diet
Includes insects and berries. Diet not well known. In summer in United States, probably feeds mostly on insects. Also known to eat many small fruits and berries, perhaps especially in southern parts of range.
Nesting
Male defends nesting territory by singing. Has a thin, rhythmic "dawn song," usually heard only before sunrise. Nest: Usually suspended at the end of a long hanging branch, under the shady canopy of a large tree (sycamore or cottonwood in Arizona), up to 50' above the ground. Nest (built mostly by female, with some help from male) is a very large globular mass of vegetation, with the entrance low on one side; made of bark strips, grass, weeds, vines, spiderwebs, and other materials. More material may be added even after incubation begins.
Climate Vulnerability
Conservation Status
