Altamira Oriole
Icterus gularis
| Conservation status | Has become more common in Texas within last half-century. Farther south, remains widespread and common. Perhaps less affected by cowbird parasitism than some orioles. |
|---|---|
| Family | Blackbirds and Orioles |
| Habitat | Open tropical woodland and edges. In our area, resident mostly in native woodland near Rio Grande in southern Texas. Farther south in Mexico and Central America, widespread in lowlands and lower foothills in open dry woods, forest edge, streamside groves, scattered trees in open country; usually avoids unbroken humid forest. |

Feeding Behavior
Forages rather slowly and deliberately in trees, mostly high but also in low undergrowth, searching for insects. Will come to feeders for sugar-water and sometimes for other items.
Eggs
4-6, or fewer in southern part of range. Pale bluish white, blotched with black and lavender. Incubation behavior poorly known, probably lasts about 2 weeks. Young: Both parents feed nestlings. Age at which young leave the nest is not well known.
Young
Both parents feed nestlings. Age at which young leave the nest is not well known.
Diet
Mostly insects and berries. Diet is not known in detail; feeds on many insects, especially grasshoppers, crickets, and caterpillars, also ants and many others, plus spiders. Also feeds on berries and small fruits, including those of hackberries and figs.
Nesting
In Texas, breeds mostly from late April to late July. Nest: Placed quite conspicuously out at the end of a horizontal branch of a tree, averages about 30' up, can be 10-80' above the ground. In the tropics, nest may be suspended from telephone wires. Nest is a very long hanging bag or pouch (with the entrance at the top), up to 2' long, woven of Spanish moss, grass, palm fibers, weeds, strips of bark; lined with plant down, hair, or feathers. Probably built by female; the process may take 3 weeks or more.
How Climate Change Will Reshape the Range of the Altamira Oriole
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.

Possible Border Wall Plans Would Be 'Devastating' for Santa Ana National Wildlife Refuge
Located in Texas’ Rio Grande Valley, the refuge features a variety of habitats that are home to a staggering diversity of birds and other wildlife. Growing evidence suggests the wall could go right through it all.
