Altamira Oriole (Female/Immature) in Mexico.

The Altamira Oriole (Icterus gularis) is a New World oriole. They are widespread in subtropical lowlands of the Mexican Gulf Coast and northern Central America, the Pacific coast and inland. They have since spread to southern Texas, but this was not until 1939.

At 9.8 inches and 2.0 oz, this is the largest oriole in genus Icterus. These birds nest in open woodland, with the nest being a very long woven pouch, attached to the end of a horizontal tree branch, sometimes to telephone wires.

Altamira Oriole (Female/Immature)

This Oriole forages high in trees, sometimes in the undergrowth. They mainly eat insects and berries.

These birds are permanent residents, and unlike the migratory orioles that breed in the US, the species is sexually monomorphic—both the males and the females have elaborate coloration and patterning. [Wikipedia]
