The yellow-bellied siskin (Spinus xanthogastrus) is a small passerine bird in the finch family Fringillidae. It breeds from Costa Rica south to southern Ecuador, central Bolivia and the highlands of northwestern Venezuela.The yellow-bellied siskin breeds in mountain oak forests at altitudes between 800–3000 m. The nest is a shallow cup of rootlets, bark, and lichen 2.4–3.7 m high in the dense foliage of a small tree in a clearing. The two or three green-tinged white eggs are laid in April or May and incubated by the female. Although not migratory, this species wanders within its range when not breeding.The yellow-bellied siskin is a small bird, 10.5 cm in length and weighing 12 g. The male is entirely black except for a bright yellow belly, tail sides and wing patches. The female is dark olive green above, and has pale yellow underparts which become brighter on the belly. She has a blackish tail and wings and also has bright yellow primary wing patches and tail sides. Young birds resemble the female, but have dusky fringes to the upperpart feathers and smaller yellow wing and tail patches. The song of this bird is a pleasant chattering twitter, and the call is a sharp pyee.The subspecies S. x. stejnegeri which occurs from extreme southeastern Peru to central Bolivia is larger and longer-billed than nominate S. x. xanthogastrus. Males have larger yellow wing patches and more extensive black on the flanks. Females of this subspecies are darker olive above than the northern birds.The yellow-bellied siskin is more of a woodland bird than the superficially similar lesser goldfinch, Spinus psaltria, and the latter species is paler, has a white wing patch, and more musical song.The yellow-bellied siskin has been relentless persecuted for the cage-bird trade in some areas such as central Costa Rica. Where it remains common, in remote or protected areas, flocks of up to 30 birds forage in the canopy for small insects and oak flowers, or descend to clearings for seeds. The males may sing socially.The phylogeny has been obtained by Antonio Arnaiz-Villena et al.

The yellow-green grosbeak (Caryothraustes canadensis) is a species of grosbeak in the family Cardinalidae.In 1760 the French zoologist Mathurin Jacques Brisson included a description of the yellow-green grosbeak in his Ornithologie based on a specimen collected in Cayenne in French Guiana. He used the French name Le Gros-bec de Cayenne and the Latin name Coccothraustes Cayanensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson. One of these was the yellow-green grosbeak. Linnaeus included a terse description, used the binomial name Loxia canadensis and cited Brisson's work. Linnaeus mistakenly claimed that the species occurred in Canada rather than Cayenne and introduced the specific name canadensis for Canada where the bird does not occur. This species is now placed in the genus Caryothraustes that was introduced by the German naturalist Ludwig Reichenbach in 1850. There are four subspecies.It is found in Brazil, Colombia, French Guiana, Guyana, Panama, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest.

Yellow-green algae or the Xanthophyceae (xanthophytes) are an important group of heterokont algae. Most live in fresh water, but some are found in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentous forms. Xanthophyte chloroplasts contain the photosynthetic pigments chlorophyll a, chlorophyll c, β-carotene, and the carotenoid diadinoxanthin. Unlike other heterokonts, their chloroplasts do not contain fucoxanthin, which accounts for their lighter colour. Their storage polysaccharide is chrysolaminarin. Xanthophyte cell walls are produced of cellulose and hemicellulose. They appear to be the closest relatives of the brown algae.

The yellow-lipped sea krait (Laticauda colubrina), also known as the banded sea krait, colubrine sea krait, is a species of venomous sea snake found in tropical Indo-Pacific oceanic waters. The snake has distinctive black stripes and a yellow snout, with a paddle-like tail for use in swimming.It spends much of its time underwater in order to hunt, but returns to land to digest, rest, and reproduce. It has very potent neurotoxic venom which it uses to prey on eels and small fish. Because of their affinity to land, banded sea kraits often encounter humans, but the snakes are not aggressive and only attack when feeling threatened.

Yellow-band disease (similar to Yellow Blotch disease) is a coral disease that attacks colonies of coral at a time when coral is already under stress from pollution, overfishing, and climate change. It is characterized by large blotches or patches of bleached, yellowed tissue on Caribbean scleractinian corals.Yellow-band disease is a bacterial infection that spreads over coral, causing the discolored bands of pale-yellow or white lesions along the surface of an infected coral colony. The lesions are the locations where the bacteria have killed the coral’s symbiotic photosynthetic algae, called zooxanthellae which are a major energy source for the coral. This cellular damage and the loss of its major energy source cause the coral to starve, and usually cause coral death. There is evidence that climate change could be worsening the disease.

They have a white or yellow eye ring that lacks the teardrop projection of Pacific-slope (E. difficilis) or cordilleran (E. occidentalis) flycatchers, white or yellowish wing bars that contrast strongly against the black wings, a broad, flat bill, and a relatively short tail when compared to other members of the genus. The upper mandible of the bill is dark, while the lower mandible is orange-pink.Their breeding habitat is wet northern woods, especially spruce bogs, across Canada and the northeastern United States. They make a cup nest in sphagnum moss on or near the ground.These birds migrate to southern Mexico and Central America.Yellow-bellied flycatchers wait on a perch low or in the middle of a tree and fly out to catch insects in flight, sometimes hovering over foliage. They sometimes eat berries or seeds.The yellow-bellied flycatcher's song can be transcribed as a rough, descending "tse-berk", which can be similar to the more common least flycatcher's snappier, more evenly pitched "che-bek." To identify the difference between the two species by sound: yellow-bellied flycatchers make the sound tse-berk at five second intervals, and the least flycatcher at one or two second intervals. The three primary call notes of yellow-bellied flycatcher are a clear, ascending "chu-wee", a sharp, gruff "peekk", and a soft, descending "pyu".

The yellow-faced honeyeater (Caligavis chrysops) is a medium-small bird in the honeyeater family, Meliphagidae. It takes both its common name and scientific name from the distinctive yellow stripes on the sides of its head. Its loud clear call often begins twenty or thirty minutes before dawn. It is widespread across eastern and south eastern Australia, in open sclerophyll forests from coastal dunes to high-altitude subalpine areas, and woodlands along creeks and rivers. Comparatively short-billed for a honeyeater, it is thought to have adapted to a diet of flies, spiders, and beetles, as well as nectar and pollen from the flowers of plants such as Banksia and Grevillea, and soft fruits. It catches insects in flight as well as gleaning them from the foliage of trees and shrubs.While some yellow-faced honeyeaters are sedentary, hundreds of thousands migrate northwards between March and May to spend the winter in southern Queensland and return in July and August to breed in southern New South Wales and Victoria. They form socially monogamous pairs and lay two or three eggs in a delicate cup-shaped nest. While the success rate can be low, the pairs nest several times during the breeding season.Honeyeaters' preferred woodland habitat is vulnerable to the effects of land clearing, grazing, and weeds. However, as it is common and widespread, the yellow-faced honeyeater is considered by the International Union for Conservation of Nature (IUCN) to be of least concern for conservation. It is considered a pest in orchards in some areas.

The yellow-bellied sunbird-asity (Neodrepanis hypoxantha) is a small species of passerine bird from the asity family. The male has black upper parts with a bluish sheen and yellow underparts, and is sometimes known simply as the yellow-bellied asity. It is found only in montane rainforests of Madagascar where it feeds on nectar that it sips from flowers, defending a good nectar source from other nectar-feeding birds. It is listed by the International Union for Conservation of Nature as "vulnerable" due to the diminution and fragmentation of its forest habitat.

The yellow-eye mullet (Aldrichetta forsteri) is a mullet of the family Mugilidae, the only species in the genus Aldrichetta. It is found around New Zealand, the Chatham Islands, and southern Australia. In New Zealand it is also known as the sprat or herring, but is neither a true sprat nor a true herring. They are also commonly called the sand mullet.The back is olive-green, and the belly is silver, usually with a yellow tinge. The eyes are a distinctive bright yellow, as its common name suggests, which easily distinguishes it from other coastal fish. They commonly grow to 25 centimeters. The greatest recorded size is 50 centimeters length and 950 grams weight.The yellow-eye mullet is similar to the flathead grey mullet, but has a more pointed head and mouth and does not grow as large. Its teeth are larger and more numerous than in a flathead mullet.They range from the surface to depths of 50 m, but usually only down to 10 m. The yellow-eye mullet schools in large numbers in summer and enters bays and estuaries, and may enter rivers. They feed on benthic detritus, algae and small invertebrates. Occasionally large schools can be seen feeding on the surface. Their greatest known age is seven years.They have a low habitat damage rate.The meat of this fish is extremely rich in omega three fatty acids. They are very nice smoked. The black lining surrounding the stomach should be removed before cooking.

The yellow-backed tanager (Hemithraupis flavicollis) is a species of bird in the family Thraupidae, the tanagers.It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname; also extreme eastern Panama in Central America. Its natural habitats are subtropical or tropical moist lowland forest and heavily degraded former forest.

The yellow-cheeked gibbon (Nomascus gabriellae), also called the golden-cheeked gibbon, yellow-cheeked crested gibbon, the golden-cheeked crested gibbon, red-cheeked gibbon, or the buffed-cheeked gibbon, is a species of gibbon native to Vietnam, Laos, and Cambodia.The yellow-cheeked gibbon is born blond and later turns black. Males carry this colouring through their lifespan and have the distinguishing golden cheeks. Females are born blonde to blend into their mother's fur but they later turn black. Females turn back to blond at sexual maturity, keeping only a black cap on the top of their heads.This diurnal and arboreal gibbon lives in primary tropical forest, foraging for fruits, using brachiation to move through the trees.The yellow-cheeked gibbon, like all gibbon species, has a unique song, which is usually initiated by the male. The female will then join in and sing with the male to reinforce their bond and announce to other gibbons that they are a pair in a specific territory. The male usually finishes the song after the female has stopped singing.Little is known about this species in the wild, but it is thought that it has a life span of approximately 46 years.

The yellow-knobbed curassow (Crax daubentoni) is a large species of bird found in forest and woodland in Colombia and Venezuela. It feeds mainly on the ground, but flies up into trees if threatened. Its most striking features are its crest, made of feathers that curl forward, and the fleshy yellow knob at the base of its bill. Females lack this fleshy yellow knob, but otherwise resemble the male in the plumage, being overall black with a white crissum (the area around the cloaca). The adult is 84-92.5 cm (33–37 in) and weighs about 2–3 kg (4.4-6.6 lbs). It eats fruits, leaves, seeds, and small animals. Unlike most other gamebirds, curassows nest off the ground, with both sexes helping in the construction. The female lays just 2 eggs - a tiny clutch compared to those of many ground-nesting gamebirds.

The yellow-billed duck (Anas undulata) is a 51–58 cm long dabbling duck which is an abundant resident breeder in southern and eastern Africa.This duck is not migratory, but will wander in the dry season to find suitable waters. It is highly gregarious outside the breeding season and forms large flocks.These are mallard-sized mainly grey ducks with a darker head and bright yellow bill. The wings are whitish below, and from above show a white-bordered green speculum.Sexes are similar, and juveniles are slightly duller than adults. The north-eastern race is darker and has a brighter bill and blue speculum.It is a bird of freshwater habitats in fairly open country and feeds by dabbling for plant food mainly in the evening or at night. It nests on the ground in dense vegetation near water. Rarely found in suburban areas, in close proximity to golf courses, parks and lakes or dams. The clutch numbers between six and twelve eggs.The male has a teal-like whistle, whereas the female has a mallard-like quack.There are two subspecies of the yellow-billed duck: A. undulata rueppelli (northern yellow-billed duck) A. undulata undulata (southern yellow-billed duck)The yellow-billed duck is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The southern nominate subspecies is declining due to competition and hybridization with feral mallards (Rhymer 2006).

Yellow-hair chicken, also called yellow-feather chicken, 黃毛雞 (Cantonese Yale: wòhng mouh gāai, Pinyin: huángmáo jī, is a breed of chicken traditionally raised for meat in China. It takes about 120 days to grow to market size compared to as little as 41 days for specially-bred broiler chickens.Yellow-hair chicken is flavorful, but takes longer and is more difficult to cook than a typical broiler as it has less fat and more meat. Outside of China it is only available in Chinese restaurants, and, even there, usually not on the English menu. The breed is being displaced in China by broiler chickens.Yellow-hair chicken is not necessarily free range, although it could be, if raised that way.
