Hepatic Tanager
Hepatic Tanager
Piranga flava
At a Glance
In mountain forests of the Southwest, this tanager is fairly common in summer among the pines and oaks. Members of a pair are often found foraging together, moving about rather slowly in the tall pines as they search deliberately for insects in the foliage. The name 'Hepatic' is a reference to the color of the male, a more liver-red or duller shade than that of our other red tanagers.

Habitat
Open mountain forests, oaks, pines. In our area, breeds at middle elevations in mountains and canyons, in forest of oaks and tall pines; also in some regions in low pinyon pine woods with a scattering of taller trees. In the tropics, lives mostly in the mountains, also locally in lowland pine savanna.

Behavior
Eggs
3-5, typically 4. Bluish green, with brown spots often concentrated at the larger end. Incubation behavior and length of incubation period not well known.
Young
Probably both parents feed the nestlings. Age at which the young leave the nest is not well known.
Feeding Behavior
Forages rather slowly and deliberately, hopping along branches and pausing to peer about at the foliage. Mostly feeds high in trees, but sometimes forages in low shrubs and rarely on the ground. Sometimes flies out to catch insects in mid-air.
Diet
Mainly insects, also berries. Apparently feeds largely on insects, including caterpillars and beetles, probably many others. Also eats berries and small fruits, especially in late summer, including wild grapes.
Nesting
Male sings to defend nesting territory. Nest site is in tall tree, often pine, oak, or sycamore, usually 15-50' above the ground. Usually placed at a fork of a horizontal branch well out from the trunk. Nest is a shallow open cup made of grass and weed stems, lined with fine grass. Apparently built mostly by the female, although male may accompany her and may help carry nest material.
Climate Vulnerability
Conservation Status
Has probably declined in some areas of Southwest in recent decades. Nests may be parasitized fairly often by cowbirds.
