Yellow-olive Flycatcher - The Yellow-olive Flatbill or Yellow-olive Flycatcher is a species of bird in the Tyrannidae family. It is found in tropical and subtopical forest and woodland in Central and South America, but over its range there are significant variations in plumage, iris-colour and voice, leading to speculations that more than one species is involved. Its plumage is overall greenish-yellow, the lores are whitish, the crown is often greyish and some subspecies have a dusky patch on the auriculars. The flat bill is black above and pale pinkish or greyish below; similar to the Yellow-margined Flatbill, but unlike the Grey-crowned Flatbill.

Yellow-plumed Honeyeater - Its natural habitats are temperate forests and Mediterranean-type shrubby vegetation.

Yellow-rumped Antwren - The Yellow-rumped Antwren is endemic to the Yungas of Bolivia and immediately adjacent Peru . It is rarely seen but has been recorded at the Cochabamba-Villa Tunari road, Chapare, Cochabamba, in 1979; in the Serranía Bellavista north of Caranavi, La Paz, in 1979-1980 and 1997, although playback surveys at the start of the breeding season in 2005 failed to find it and it may no longer be present there; Cerro Asunta Plata, La Paz in 1993; Rio Paracti, Chapare, Cochabamba in 2000, and between San Juan del Oro and Putina Punco, Puno in 2007. It may have been overlooked to some extent, and it may possibly occur in reasonably high density along the Manu road, where it occurs above its congener T. calliota in the only known area of overlap. A population estimate exceeding 10,000 individuals has been suggested, although the species does appear to be naturally rare and patchily distributed, and playback surveys in several areas of prime habitat have failed to find it. Numbers have almost certainly declined substantial

Yellow-rumped Cacique - The male is in average 28 cm long and weighs about 104 g, with the female 23 cm long and weighing 60 g approximately. The Yellow-rumped Cacique is a slim bird, with a long tail, blue eyes, and a pale yellow pointed bill.

Yellow-rumped Warbler - Since 1973, American Ornithological Union has elected to merge these passerine birds as one species. The Myrtle and Audubon's forms were apparently separated by glaciation during the last ice age, and developed distinguishing physical characteristics. When it was shown, however, that they were able to interbreed, they were no longer considered as separate species. The two Middle American subspecies, goldmani and nigrifrons are sedentary and diverged from the northern migratory subspecies in the Pleistocene, and so probably represent separate species.

Yellow-shouldered Amazon - The Yellow-shouldered Amazon is mainly green and about 33 cm long. 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 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. Its beak is horn coloured.

Yellow-shouldered blackbird - The nominate form of the Yellow-shouldered Blackbird was first described from Puerto Rico and Vieques in 1862 by Philip Sclater as Icterus xanthomus. The species is closely related to, and possibly derived from, the Red-winged Blackbird . The Tawny-shouldered Blackbird , a species from Cuba and Haiti, is morphologically intermediate between A. xanthomus and A. humeralis. Until recently, some authors considered A. xanthomus as a subspecies of A. humeralis. The 1983 American Ornithologists' Union edition considered A. xanthomus, together with A. humeralis, a superspecies. The main physical difference between A. xanthomus and A. humeralis resides in their bills, with A. humerali's being broader toward the base. The recognized subspecies A. x. monensis, or Mona Yellow-shouldered Blackbird, was described by Barnes in 1945 from the islands of Mona and Monito.

The adult male has a black beak and pinkish-red eye-rings, and the female has a bone-coloured beak and grey eye-rings. In flight, Yellow-tailed Black Cockatoos flap deeply and slowly, and with a peculiar heavy fluid motion. Their loud eerie wailing calls carry for long distances.

Yellow-tailed Oriole - The Yellow-tailed Oriole is 22-23 cm long and weighs 70 g. It is mainly yellow with a black back, lower face and upper breast. The wings are black with a yellow epaulet and the tail is black with yellow sides. This is the only oriole with prominent yellow in the tail, hence the species’ name. The sexes are similar, but young birds have the black on the back and tail replaced with olive-green.

Yellow-tipped Antbird - The Imeri Warbling Antbird is a species of bird in the Thamnophilidae family. Until recently, it was considered a subspecies of Hypocnemis cantator, but based on vocal differences and to a lesser degree differences in plumages it has been recommended treating them as separate species. As presently defined, the Imeri Warbling Antbird includes a single subspecies, perflava.

Yellow-tufted Bulbul - This is a bird of jungle and wooded farmland. Despite its restricted range, it is quite readily found at sites such as Horton Plains and Victoria Park in Nuwara Eliya. It builds its nest in a bush; two eggs is a typical clutch.

Yellow-tufted Honeyeater - It was initially described by ornithologist John Latham in 1802 and given several names, initially Muscicapa auricomis and later Turdus melanops. The latter name was retained as a nomen protectum and the former a nomen oblitum as the epithet melanops has been used consistently for over a century. It belongs to the honeyeater family Meliphagidae. More recently, DNA analysis has shown honeyeaters to be related to the Pardalotidae, and the Petroicidae in a large corvid superfamily; some researchers considering all these families in a broadly defined Corvidae.

Yellow-winged Vireo - This vireo occurs from 2000 m to the timberline in the canopy of mountain forest, sometimes feeding in undergrowth or tall second growth. The small cup nest is built in the fork of a small branch 3–20 m high in a tree or scrub and the clutch is two dark-spotted white eggs. Both sexes construct the nest, incubate the eggs and feed the young.

Yellowbill - It has a widespread distribution across the tropical evergreen forests of Africa, including West and Central Africa, and the down the coast of Eastern Africa from Kenya to South Africa. It ranges from dense forest to riverine forest and forest edges, with one small population in Ethiopia living in arid bushland. In the forest it typically lives in the subcanopy at between 8-30 m.

Yellowhammer - The Yellowhammer is a robust 15.5–17 cm long bird, with a thick seed-eater's bill. The male has a bright yellow head, yellow underparts, and a heavily streaked brown back. The female is much duller, and more streaked below. The familiar, if somewhat monotonous, song of the cock is often described as A little bit of bread and no cheese.

Yellowhead - The Yellowhead and the Whitehead have sympatric distributions as, conversely, the latter is found only on the North island and several small islands surrounding it. Although abundant in the 1800s, particularly in beech forests from Nelson and the Marlborough Sounds to Southland and Stewart Island/Rakiura, they declined dramatically in the early 1900s due to the introduction of ship rats and mustelids. Today they have vanished from nearly 75% of their former range. In New Zealand, the Mohua has the status of a protected threatened endemic species. Conservation efforts are being made to ensure its survival and Mohua populations have been established on several predator-free offshore islands, such as Breaksea Island in Fiordland and Ulva Island.
