Top 20 Most Common Bird in Bali

The plaintive cuckoo is fairly small, measuring about 21–24 cm (8.3–9.4 in) long. The adult male is grey-brown above and orange below with a grey head, throat and upper breast. The tail feathers have white tips. The legs and feet are yellow, the eye is red and the bill is black above and yellow below. The adult female is sometimes similar to the male but often occurs in a "hepatic" morph. This form is reddish-brown above with dark bars. The underparts are paler with fainter barring. There is a pale stripe over the eye and the tail has dark bars along its whole length. Juvenile birds are similar to hepatic females but are paler and have dark streaks rather than bars on the crown and throat. The male has several plaintive whistling calls. These include an ascending series of three-note phrases and a series of 11 or 12 descending notes.

The spotted Dove is a medium-sized bird that is swift in flight. It prefers to live year-round in warm climates in suburban areas, especially in parks. Their nests are mostly made out of sticks and they like to dine on insects and seeds.

This bird is shiny blackish-brown above with a greenish gloss, including its rump; sometimes looks black and hooded. Chest black; belly to flanks pale grey with fine black speckles at margins. Wing tips are rounded; underwing is black. Tail black, rounded with shallow notch but lacking the white specks found in the very similar glossy swiftlet (Collocalia esculenta). A distinguishing feature between the two species is that the glossy swiftlet has a tuft of feathers on its hind toe but the cave swiftlet has a naked toe. It is 9 to 11.5 cm (3.5 to 4.5 in) in length. The call is a high-pitched "cheer-cheer".

The eyebrow buzz (Pycnonotus goiavier), is a common songbird from the family of the buulbuuls. The eyebrow bulge is found in large parts of Southeast Asia and the Indian Archipelago.

The scaly-breasted munia is about 11–12 centimetres (4.3–4.7 in) long and weighs 12–16 grams (0.026–0.035 lb). The adult has a stubby dark bill typical of grain eating birds, brown upperparts and a dark brown head. The underparts are white with dark scale markings. The sexes are similar, although males have darker markings on the underside and a darker throat than females. Immature birds have pale brown upperparts, lack the dark head found in adults, and have uniform buff underparts that can be confused with juveniles of other munia species such as the tricolored munia (Lonchura malacca) across the Asian and island populations and the black-throated munia (Lonchura kelaarti) in parts of India or Sri Lanka. Populations within their wide distribution range show variations in plumage color and size. Along with other Estrildines, these species are thought to have originated in Asia. The species has been introduced to other parts of the world due to its popularity as a cage bird and populations have established in the wild.

The eurasian Tree Sparrow (Passer montanus) is a widespread sparrow of the European mainland that has been introduced to some parts of North America. Eurasian Tree Sparrow is very similar to the House sparrow (Passer domesticus) but it's smaller and neater. It prefers more natural habitats, at the edges of human activity, and inhabits farmlands, parklands, and open woods.

The Javan munia (Lonchura leucogastroides) is a species of estrildid finch found in Southern Sumatra, Java, Bali and Lombok, Indonesia. Introduced in Singapore and S Malay Peninsula; possibly introduced in Sumatra. It is found in subtropical/ tropical dry shrubland and grassland habitat. The status of the species is evaluated as Least Concern. They are known to feed on algae, and grasses.

The grey-cheeked green pigeon (Treron griseicauda) is a species of bird in the family Columbidae. It is endemic to Indonesia.

In most subspecies, the underparts of both male and female are bright yellow, the backs are a dull brown colour. The forehead, throat and upper breast of the adult male is a dark, metallic blue-black. In the Philippines the males of some subspecies have an orange band on the chest, in Wallacea and northern New Guinea some subspecies have most of the underparts blackish, and in southern China and adjacent parts of Vietnam most of the underparts of the male are greyish-white.

Cattle Egrets are short, thick-necked egrets. Their name refers to their preference to follow along with livestock as they forage in fields. Cattle Egrets were native only to Africa until the late 1800s when they somehow made their way throughout the Americas. They can often be found along airport runways waiting for planes to take off and blow insects out of the grass and weeds. They also follow behind farm equipment and do the same thing.

The Pacific swallow (Hirundo tahitica) is a small passerine bird in the swallow family. It breeds in tropical southern Asia and the islands of the south Pacific. It is resident apart from some local seasonal movements. This bird is associated with coasts, but is increasingly spreading to forested uplands. The hill swallow was formerly considered conspecific. This species is a small swallow at 13 cm. It has a blue back with browner wings and tail, a red face and throat, and dusky underparts. It differs from the barn swallow and the closely related welcome swallow in its shorter and less forked tail. The Pacific swallow builds a neat cup-shaped nest, constructed with mud pellets collected in the beak, under a cliff ledge or on a man-made structures such as a building, bridge or tunnel. The nest is lined with softer material, and the clutch is two to three eggs. It is similar in behaviour to other aerial insectivores, such as other swallows and the unrelated swifts. It is a fast flyer and feeds on insects, especially flies, while airborne.

The zebra Dove is a small dove found in dense forests, open fields, farmlands, and similar suburban areas. Unlike other dove species, this ground-dwelling bird likes to forage alone or in pairs, but not in large groups. The call of this slender dove is often described as very pleasant. Very common in urban areas, they are quite comfortable around humans.

The olive-backed tailorbird (Orthotomus sepium) is a species of passerine bird formerly placed in the "Old World warbler" assemblage, it but now placed in the family Cisticolidae. It is endemic to the islands of Java, Madura Island, Bali and Lombok.

Adult white-breasted waterhens have mainly dark grey upperparts and flanks, and a white face, neck and breast. The lower belly and undertail are cinnamon coloured. The body is flattened laterally to allow easier passage through the reeds or undergrowth. They have long toes, a short tail and a yellow bill and legs. Sexes are similar but females measure slightly smaller. Immature birds are much duller versions of the adults. The downy chicks are black, as with all rails.

Ioras have a pointed and notched beak with a culmen that is straight. The common iora is sexually dimorphic, males in the breeding season have a black cap and back adding to a black wing and tail at all seasons. Females have greenish wings and an olive tail. The undersides of both are yellow and the two white bars on the wings of the male are particularly prominent in their breeding plumage. The males in breeding plumage have a very variable distribution of the black on the upperparts and can be confused with Marshall's iora, however, the latter always has white tips to the tail. The nominate subspecies is found along the Himalayas and males of this population are very similar to females or have only a small amount of black on the crown. In northwestern India, septentrionalis is brighter yellow than others and in the northern plains of India humei males in breeding plumage have a black cap and olive on the upper mantle. In southwestern India and Sri Lanka multicolor has the breeding males with a jet black cap and mantle. The forms in the rest of southern India are intermediate between multicolor and humei with more grey-green on the rump (formerly considered as deignani but now used for the Burmese population). Several other populations across Southeast Asia are designated as subspecies including philipi of southern China and northern Thailand/Laos, deignani of Myanmar, horizoptera of southern Myanmar and the island chain of Sumatra, cambodiana of Cambodia, aeqanimis of Palawan and northern Borneo, viridis of Borneo and scapularis of Java and Bali.

The edible-nest swiftlet generally measures 14cm (5.5. in). The upper part of the body is blackish-brown; the under part of the body ranges in color from white to blackish-brown. The tail has a slight notch. It weighs 15 to 18 grams and the wings are long and narrow. The bill and feet are black. The subspecies A. f. micans is paler and greyer while A. f. vestitus is darker with a rump that is less obviously paler. At breeding colonies, the bird emits high-pitched and burbling calls. They also emit a rattling call used for echolocation.

The striated swallow is 19 cm long with a deeply forked tail. It has blue upperparts other than a reddish collar (sometimes absent) and streaked chestnut rump. The face and underparts are white with heavy dark streaking. The wing are brown. The sexes are alike but juveniles are duller and browner, with a paler rump and shorter outer tail feathers. There are four races: C. s. striolata breeds in Taiwan, The Philippines and Indonesia. C. s. mayri breeds from northeastern India to northwestern Myanmar and northeastern Bangladesh. It has broader streaks than nominate striolata. C. s. stanfordi breeds from northeastern Myanmar to northern Thailand. It has broad streaks. C. s. vernayi breeds locally in western Thailand. It is more rufous below than the nominate race, and is only faintly streaked on the rump. The contact call is pin, the alarm is chi-chi-chi, and the song is a soft twittering. This species, particularly subspecies mayri is very similar to red-rumped swallow of the race japonicus, but is larger, more heavily streaked, and has a less distinct neck collar.

This is a large species of cuckoo. The head is black, upper mantle and underside are black glossed with purple. The back and wings are chestnut brown. There are no pale shaft streaks on the coverts. The eyes are ruby red. Juveniles are duller black with spots on the crown and there are whitish bars on the underside and tail. There are several geographic races and some of these populations are sometimes treated as full species.

The rock Pigeon is a wild ancestor of all domestic and feral pigeons, inhabiting coasts, cliffs, and caves. Pairs nest in rock crevices, often mating for life. They are known for their ability to fly very long distances to return to their homes, navigating using the sun's position and the earth's magnetic fields. Thanks to this ability, pigeons were used as messengers, particularly during World Wars I and II.

The Javan pond heron (Ardeola speciosa) is a wading bird of the heron family, found in shallow fresh and salt-water wetlands in Southeast Asia. Its diet comprises insects, fish, and crabs. The Javan pond heron is typically 45 cm long with white wings, a yellow bill with a black tip, yellow eyes and legs. Its overall colour is orange, slaty and white during mating season, and brown and flecked with white out of the mating season. The non-breeding plumage is similar to that of the Chinese and Indian pond herons and is virtually indistinguishable in the field. It breeds from June to September. It is migratory. Widespread throughout its large range, the Javan pond heron is evaluated as Least Concern on the IUCN Red List of Threatened Species.
