Yellow-shouldered Amazon
Amazona barbadensis
Large green parrot of desert Caribbean areas, including mainland. All green with yellow face, yellow shoulder patch, and orange wing patch. Sexes similar. A threatened species, uncommon in areas where it’s trapped for the pet trade but locally common in safer areas. Usually in pairs or groups, often large flocks at roosts. Always in desert scrub areas searching for cactus and other fruits, seeds, and nectar-rich flowers. Voice a harsh scream similar to other Amazona parrots but somewhat higher pitched. Similar to Orange-winged Parrot, which lacks yellow shoulders and has a blue area above eyes.
Identification
The yellow-shouldered amazon is mainly green and about 33 cm long (~13 inches). It has a whitish forehead and lores, and a yellow crown, ocular region and - often - ear coverts and chin. The bare eye-ring is white. The thighs and the bend of the wing ("shoulder") are yellow, but both can be difficult to see. The throat, cheeks and belly often have a bluish tinge. As most members of the genus Amazona, it has broad dark blue tips to the remiges and a red wing-speculum.<p>The yellow-shouldered amazon can be distinguished from the very similar orange-winged amazon by the latter's lack of yellow on its shoulders and blue colouration around the eyes. Another way of distinguishing it from other Amazona species is its somewhat higher pitched vocalizations.
Taxonomy
The yellow-shouldered amazon was described and illustrated in 1738 by the English naturalist Eleazar Albin in his A Natural History of Birds based on live specimen. Albin believed that the parrot had come from Barbados and used the English name, the "Barbadoes parrot". Using Albin's account, both Mathurin Jacques Brisson in 1760 and John Latham in 1781 included a description of the parrot in their books on birds. When in 1788 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae, he included the yellow-shouldered amazon, coined the binomial name Psittacus barbadensis and cited Latham's work. Gmelin specified the type locality as Barbados but this parrot species is not found on the island and Venezuela is the type locality. The yellow-shouldered amazon is now placed with around thirty other species in the genus Amazona that was introduced by the French naturalist René Lesson in 1830. The genus name is a Latinized version of the name Amazone given to these parrot in the 18th century by the Comte de Buffon, who believed they were native to Amazonian jungles. The specific barbadensis denotes Barbados. The species is monotypic: no subspecies are recognised.

Range and habitat
A. barbadensis is endemic to northern Venezuela, Bonaire (which may have less than 400 birds), and other islands in the area. On the Venezuelan island of Margarita, it is extirpated from the east side, which is heavily commercialized and a popular tourist destination, existing only on the Macanao Peninsula. Also native to Aruba, it went locally extinct by 1947. In January of 2024, a population of over two dozen of these birds was reintroduced to the island and is doing well. An introduced population exists on Curaçao. Unlike other Amazona members, it is typically found in arid habitats, such as desert scrub and dry forests.

Behavior
It feeds on fruits, seeds, and flowers, frequently consuming parts of cactus plants. The parrot is able to survive with minimal water, getting a large amount of moisture from their diet. This is especially clear on La Blanquilla, a small island with no natural bodies of water. The cacti that they so often eat are filled with liquid, in both the stems and fruits, and this keeps them alive in their arid environment.<p>The yellow-shouldered amazon typically nests in holes in trees, cliffs, or cacti, and lays 2-5 eggs. Total clutch size and hatching success of this species on Margarita Island are among the highest documented for the genus Amazona, suggesting a high reproductive potential for the species It is highly gregarious, and can sometimes roost in communally in tall trees, forming groups of as many as 700. The population on Bonaire appears to breed slower than is typical for the species, bringing it in line with other members of the genus.

Audubon's Oriole
Icterus graduacauda
Entirely yellow body with greenish back and black hood. Young birds slightly paler than adults; they develop black hood within a couple months of hatching. Tends to be more secretive than other orioles. A Mexican species with limited U.S. range. Most similar to Scott's Oriole but note greenish, not black, back; range does not overlap. Found in wooded habitats with dense brushy undergrowth. Sometimes visits feeders for fruit and seed. Song a slow series of low-pitched whistles.
Black Grasswren
Amytornis housei
Small chestnut-and-black bird with a long tail, found in areas with large rocky sandstone boulders and dense spinifex grass of the northwestern Kimberley region of Western Australia, with most sightings from the Mitchell Plateau. Rich chestnut-brown above, black below, the head and breast liberally streaked with white.
Purple-crowned Fairy
Heliothryx barroti
Flashy, rather large hummingbird of humid tropical lowlands. Favors forest edges, adjacent clearings with scattered trees and flowering bushes, and gardens. Feeds at all levels, but often in the canopy, hovering with its tail cocked and frequently flashed open to show extensive white. Note the gleaming snow-white underparts, brilliant emerald-green upperparts, and flashy white outer tail feathers. Bill is medium-length, black, and sharply pointed (often pierces flower bases to get nectar). Sexes similar overall, but female lacks purple crown of male, which can be hard to see, and has a longer tail.
