The Altamira oriole (Icterus gularis) is a New World oriole. The bird is 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. [2]

Contents

At 25 cm (9.8 in) and 56 g (2.0 oz), this is the largest oriole in genus Icterus . The bird nests 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.

This bird 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.

Description

Both males and females have a black mandible and throat, as well as a black back and long black tail. Wings are black, but the remiges and rectrices (flight feathers) are fringed with white. These form a single white wing bar and white wing spots when folded. The secondary coverts form orange epaulets. The underside is almost uniformly orange or yellowish-orange. In general, immature specimens have an olive back, and a dull yellow on its head and its body. The first-year bird is similar to the adult, but it has an olive, not black, back, and yellow-olive tail. [3] [4]

Behavior

The bird lives in semi-arid areas with scattered trees, and open riparian woodland. The bird is a solitary nester as well, with an average of a quarter kilometer between nests. Little aggression has been observed in breeding season from this bird, and it is not known to be territorial. [5]

Reproduction

In Texas, their breeding season ranges from late April to late July. Their nest resembles a small pouch made of moss, grass, palm fibers, weeds, strips of bark, and is lined with feathers. The nest may also hang from telephone wires. The nest is assumed to be built by the female, but it is not known how long this takes. 4–6 eggs are laid, and nestlings are fed and cared for by both parents. [2]

Diet

The Altamira oriole is a forage gleaner, searching for food through the tree-tops to the near-ground bottom of the tree. Its diet includes fruit (small fruits, hackberries and figs) and insects, such as grasshoppers, crickets, and caterpillars. [2]

Voice

The song of the Altamira oriole is a series of clear, slow musical whistles. In contrast, the Altamira's calls are harsh whistles, rasping chatter, and nasal "ike"s. [6]

Icterids or New World blackbirds make up a family, the Icteridae, of small to medium-sized, often colorful, New World passerine birds. Most species have black as a predominant plumage color, often enlivened by yellow, orange, or red. The species in the family vary widely in size, shape, behavior, and coloration. The name, meaning "jaundiced ones" comes from the Ancient Greek ikteros via the Latin ictericus. This group includes the New World blackbirds, New World orioles, the bobolink, meadowlarks, grackles, cowbirds, oropendolas, and caciques.

The western meadowlark is a medium-sized icterid bird, about 8.5 in (22 cm) in length. It nests on the ground in open grasslands across western and central North America. It feeds mostly on bugs, but will also feed on seeds and berries. The western meadowlark has distinctive calls described as watery or flute-like, which distinguish it from the closely related eastern meadowlark. The western meadowlark is the state bird of six states: Montana, Kansas, Nebraska, North Dakota, Oregon, and Wyoming.

<span class="mw-page-title-main">Baltimore oriole</span> Species of bird

The Baltimore oriole is a small icterid blackbird common in eastern North America as a migratory breeding bird. It received its name from the resemblance of the male's colors to those on the coat-of-arms of 17th century Lord Baltimore. Observations of interbreeding between the Baltimore oriole and the western Bullock's oriole, Icterus bullockii, led to both being classified as a single species, called the northern oriole, from 1973 to 1995. Research by James Rising, a professor of zoology at the University of Toronto, and others showed that the two birds actually did not interbreed significantly.

It is a bird associated with open habitats, including disturbed land from agriculture and deforestation.

<span class="mw-page-title-main">Audubon's oriole</span> Species of bird

Audubon's oriole, formerly known as the black-headed oriole, is a New World passerine inhabiting the forests and thickets of southeastern Texas and the Mexican coast. It is the only species to have a black hood and yellow body. It is divided into four subspecies and two allopatric breeding ranges. The westernmost range extends from Nayarit south to southern Oaxaca, whereas the eastern range stretches from the lower Rio Grande valley to northern Querétaro. The most common in the western range are the subspecies I. g. dickeyae and I. g. nayaritensis; I. g. graduacauda and I. g. audubonii can be found in the eastern range. Like most Central American birds, it is not a migratory species and does not display significant sexual dimorphism. DNA analysis of the ND2 and cyt-b genes strongly suggests that I. graduacauda is most closely related to I. chrysater, the yellow-backed oriole. It is a member of the genus Icterus and therefore should not be confused with the Old World orioles.
