They mainly eat insects and berries. Altamira Oriole: Largest North American oriole, bright yellow-orange body, black back, mask, bib, and tail. Attractive orange-and-black oriole of the Yucatan Peninsula, found in brushy woodland, forest edge, and semi-open areas with hedges and scattered trees. In our area, resident mostly in native woodland near Rio Grande in southern Texas. Most blackbirds and orioles are slender, long-tailed birds while the grassland loving meadowlarks, Bobolink and cowbirds have chunkier bodies and short tails. The parasitic cowbirds and their hosts. Both Bronzed and Brown-headed Cowbird eggs have been found in Altamira nests (Friedmann & Kiff 1985, Brush & Bray, unpub. Wilson Bull. Most occur in the Lower Rio Grande Valley (LRGV), in native Tamaulipan thornscrub and riparian habitat, and occasionally in rural or suburban habitat (Oberholser 1974, Brush unpub. Altamira Oriole Icterus gularis. One species, the Slender-billed Grackle, is presently listed as extinct, also due to the loss of its wetland habitat. The secondary coverts form orange epaulets. Both males and females have a black mandible and throat, as well as a black back and long black tail. The Icteridae include some of the most abundant bird species in North America. No further evidence of breeding was observed but the atlaser noted that Altamiras had been recorded a number of times on the nearby Chaparral Wildlife Management Area (B. Ortego, pers. Pleasants, B. Y. Condor 88:11-25. vol 49, no 1. pp. Very rare on BBS routes, Altamiras occur regularly, in numbers>10, on three LRGV Christmas Bird Counts (Santa Ana, Anzalduas-Bentsen, and Falcon Dam State Park; Root 1988), and irregularly or in very small numbers on four other LRGV counts and two other counts in the United States. As in many other tropical orioles, but unlike temperate species, the sexes are similar in plumage. e-mail: Little aggression has been observed in breeding season from this bird, and it is not known to be territorial. Feeds on caterpillars, insects, fruits, and berries. This map depicts the seasonally-averaged estimated relative abundance, defined as the expected count on an eBird Traveling Count starting at the optimal time of day with the optimal search duration and distance that maximizes detection of that species in a region. The Altamira Oriole has a large range of 560,000 square kilometers. This bird forages high in trees, sometimes in the undergrowth. Relative abundance. In open woodlands, females find a high branch and then weave a remarkable hanging nest that can be up to 26 inches long. Like other orioles, they sing rich, sweet whistles interspersed with percussive clucks and chatters. Found. 1993. Oberholser, H. C.  1974. eBird data from 2014-2018. 56 (A. Poole and F. Gill, eds.). In the 1960s and 1970s, Altamiras became established at Santa Ana National Wildlife Refuge (26098-A2), where 24 nests were found in 1964 and at least 18 in 1974 (Pleasants 1993).

In the case of the meadowlarks, it is their pleasant prairie songs that bring them recognition. Most blackbirds are very social in nature with some species taking this behavior to an extreme in southern fields and wetlands during the winter months. Young birds duller yellow. Increasingly common, and are breeding residents along the Rio Grande River along the Texas and Mexico border. Large bright orange oriole with thick dark bill, found in open shrubby woodland. They can be easy to detect in the morning, especially in spring and summer, when males sing the most. They have since spread to southern Texas, but this was not until 1939. Swift, strong flight on rapid wing beats. Despite these differences in body shape, all blackbirds share a sharp, straight bill that can be used to forage for both small creatures and grain. Limited black on face and throat; black back and wings with white wingbar and orange shoulder patch. Elsewhere, look and listen for this species in taller trees near water. It is not believed to be in danger of decline, and as a result, this species warrants a conservation rating of Least Concern. There are many different species of orioles, and thus, many different things to learn about them! Fledglings are often seen foraging in such habitats, even when not accompanied by adults. Resident from the southern tip of Texas south through eastern and southern Mexico to the Yucatan, Belize, and northern Central America, the Altamira Oriole has a global population estimated to be as much as 5 million individual birds.
