It formerly bred in southern Asia, mainly in India, extending east to Borneo, but is now restricted to two small breeding populations; mainly in Assam and Cambodia. Populations disperse widely after the breeding season. This large stork has a massive wedge-shaped bill, a bare head and a distinctive bare neck pouch. During the day, they soar in thermals along with vultures with whom they share the habit of scavenging. Although mainly feeding on carrion and offal, they will sometimes prey on vertebrates. They are named for the stiff "military" gait when walking on the ground. Large numbers once lived across Asia but have declined to the point of being endangered. The total population in 2008 was estimated at around a thousand. In the 19th Century, they were especially common in the city of Calcutta, where they were referred to as the "Calcutta Adjutant", valued for their service as scavengers and used in the logo of the city municipal c

Greater Akialoa - The Oʻahu ʻAkialoa was a species of finch in the Fringillidae family. The Oʻahu ʻAkialoa was a species of Akialoa, or long-billed insectivorous bird that was that was found in the high elevation forest. It was a dull colored species, dull green on the belly, bright green on tail on rump and tail, dark olive-grey back and speckled yellow and green on the head. It was endangered from the loss of habitat; it was very prone to Avian Flu, a disease that was introduced by the mosquito. This bird was mainly an insectivore using its bill to probe through the bark in search of bugs to eats. It also used its long bill to go into flowers to reach their stores of nectar. When the forests are cleared the bird could not find any food, as a result, they would starve. The birds were also weak against the natural diminishing factors like weather and competition from other native nectar feeding birds. Scientists were sure that this bird was still common in the 1860’s, evidence found by Perkins. Afterward, few reports came in,

Greater Ani - This ani is found in mangrove swamps, semi-open woodland near water, and the edges of forests. It is a seasonal migrant in at least some parts of its range. The nest, built communally by several pairs, is a deep cup lined with leaves and placed usually 2-5 m high in a tree.

In flight, the whitish underwing contrasts with the darker body. The iris of the eye is whitish, distinguishing the bird from any similar species. The bill is mainly blue-grey and the feet and cere are yellow. Juvenile birds have rufous instead of grey on the tail, streaked flanks and a dark eye.

Greater koa-finch - The bird was about 10 in long when fully grown. It was the largest known honey-creeper, although its typical weight is unknown. The bird is sexually dimorphic; the male was brilliant scarlet-orange on head, neck, and breast, with lighter orange on its bottom, and olive brown with orange touches on back, wings, and tail; however, the female was brownish olive, and somewhat lighter below. It had a thick black bill which allowed it to break open seed pods that were found in the trees. In historical times, its range was largely confined to the Kona District of the island of Hawaiʻi, although it was observed in the Kīlauea area in 1895 . In Kona, it co-occurred with the closely related Lesser Koa Finch , and the Kona Grosbeak.

Greater Racket-tailed Drongo - The Greater Racket-tailed Drongo, Dicrurus paradiseus, is a medium-sized Asian bird which is distinctive in having elongated outer tail feathers with webbing restricted to the tips. They are placed along with other drongos in the family Dicruridae. They are conspicuous in the forest habitats often perching in the open and by attracting attention with a wide range of loud calls that include perfect imitations of many other birds. It has been suggested that these imitations may help in the formation of mixed-species foraging flocks, a feature seen in forest bird communities where many insect feeders forage together. These drongos will sometimes steal insect prey caught or disturbed by other foragers in the flock. They are diurnal but are active well before dawn and late at dusk. Owing to their widespread distribution and distinctive regional variation, they have become iconic examples of speciation by isolation and genetic drift.

Greater Yellow-headed Vulture - The Greater Yellow-headed Vulture feeds on carrion and locates carcasses by sight and by smell, an ability which is rare in birds. It is dependent on larger vultures, such as the King Vulture, to open the hides of larger animal carcasses, as its bill is not strong enough to do this. Like other New World Vultures, the Greater Yellow-headed Vulture utilizes thermals to stay aloft with minimal effort. It lays its eggs on flat surfaces, such as the floors of caves, or in the hollows of stumps. It feeds its young by regurgitation.

It grows to 16 centimetres in length, of which half is the tail, which, as the name implies, is often displayed fanned out. This reveals that the outer tail feathers that are light and the centre ones are dark. Some subspecies are found in a darker plumage, notably the "Black fantail" morph seen in up to 25% of South Island birds and less than 1% of North Island birds .

Grey Flyeater - The Ashy Gerygone or Mountain Gerygone is a species of bird in the Acanthizidae family. It is found in Indonesia and Papua New Guinea. Its natural habitat is subtropical or tropical moist montanes.

Grey Francolin - The Grey Francolin Francolinus pondicerianus is a species of partridge found in the plains and drier parts of South Asia.

Both sexes typically have light gray underparts, medium-gray upperparts, and a partial black cap on the back of an otherwise white head. Birds on the Pacific coast of Washington and Oregon states have more extensive black on the head and noticeably darker backs with conspicuous white streaks. Individuals from the southern Rockies have black caps that fail to reach forward as far as the eye, giving that race a noticeably more white-headed appearance. Juvenile plumage is sooty gray all over, though slightly darker on the head.

Grey Partridge - The Grey Partridge is a rotund bird, 28–32 cm long, brown-backed, with grey flanks and chest. The belly is white, usually marked with a large chestnut-brown horse-shoe mark in males, and also in many females. Hens lay up to twenty eggs in a ground nest. The nest is usually in the margin of a cereal field, most commonly Winter wheat. The only major and constant difference between the sexes is the so-called cross of Lorraine on the tertiary coverts of females – these being marked with two transverse bars, as opposed to the one in males. These are present after around 16 weeks of age when the birds have moulted into adult plumage. Young Grey Partridges are mostly yellow-brown and lack the distinctive face and underpart markings. The song is a harsh kieerr-ik, and when disturbed, like most of the gamebirds, it flies a short distance on rounded wings, often calling rick rick rick as it rises. They are a seed-eating species, but the young in particular take insects as an essential protein supply. During the fi

Grey Peacock-Pheasant - The Grey Peacock-pheasant, Polyplectron bicalcaratum also known as Burmese Peacock is a large Southeast Asian member of the order Galliformes. It is rather closely related to the peafowl , and like these – and like most other Polyplectron – has brilliant eyespots on its plumage. It is the national bird of Myanmar.

Grey Potoo - This potoo is a large cypselomorph bird related to the nightjars and frogmouths, but like other potoos it lacks the bristles around the mouth found in the true nightjars. It is 33-38cm long and pale greyish to brown, finely patterned with black and buff, camouflaged to look like a log; this is a safety measure to help protect it from predators, but its mode of perch is also a camouflage. It has large orange eyes.

Grey Shearwater - The Grey Petrel is a member of the Procellaria genus, and in turn is member of the Procellariidae family, and the Procellariiformes order. As a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns. Although the nostrils on the Prion are on top of the upper bill. The bills of Procellariiformes are also unique in that they are split into between 7 and 9 horny plates.
