Forages in open pastures, fields, and wetlands.

The bare-faced ibis occurs in open areas such as wet meadows, savannas, marshes, and rice fields. The ibis is usually near sea level but was recorded in Venezuela and Colombia. When an ibis is about to lay its eggs it builds a nest out of sticks and twigs to put them in and it will lay between 2 and 5 eggs and will then sit on them for protection purposes for up to three weeks.

行为
Bare-faced ibises are usually seen in large flocks of their own species or with other species of ibis, sometimes even found with domestic animals. They live in close range neighboring amongst other flocks of ibis, typically known for the closest living habitats that range from being 100 meters away from the nearest neighbor. They are not very territorial towards other ibis birds, and are rarely found alone, but most of the time their aggression is limited to food robbery from another ibis or animal. Regarding nesting behavior, it is less aggressive when compared to other species of ibis. The males have a larger bill than the females relative to their body sizes, and sexual selection is not as intense as it is in other species. They share nests with other species as well.

Cabot's Tragopan
Tragopan caboti
This creamy, partridge-like beauty is the only tragopan in its range and the world’s only pale-bellied tragopan. A thickset bird, usually encountered foraging in pairs in mid-altitude hill forest. Male is pale below and intricately spotted above, with pale polka dots on a black-and-chestnut background; has a similarly black-and-chestnut head with bright orange facial skin. Female is dark gray-brown with a slightly paler face and belly; wings and belly streaked paler. During courtship, male drums wings loudly and gives a bizarre, scarily infant-like waaah! followed by loud grunting notes.
Common Hill Myna
Gracula religiosa
Glossy black myna with bright yellow head wattles. Also note bright candlewax-orange bill and white wing patches that are most apparent in flight. A species of mature humid forest and forest edge, often seen in pairs or small flocks flying between or perched up in tall trees. Famed for its wide repertoire: gives a myriad of screams, squeaks, chirps, and whistles. Threatened by its popularity in the cage bird trade.
Pale-vented Pigeon
Patagioenas cayennensis
Large pigeon of marshy savannas, riversides, open areas with scattered trees, locally even in towns, such as Villahermosa, Mexico. Gray head contrasts with pinkish body, and whitish belly does not contrast strongly with plain grayish tail; compare darker Red-billed Pigeon, which often occurs in same areas but prefers drier and more forested habitats. Also note black bill of Pale-vented, and subtly distinctive song: after long introductory coo, repeated phrase is typically a 3-syllable "who’koo-koo", unlike 4-syllable "oo’koo-koo-koo" of Red-billed.
