Top 20 Most Common Bird in Nong Khai

These 13–14-cm long warblers have short rounded wings, a longish tail, strong legs and a short black bill. In breeding plumage, adults are grey-brown above, with a short white supercilium and rufous fringes on the closed wings. The underparts are whitish-buff. The sexes are identical. In winter, the upperparts are a warmer brown, and the underparts more buff. The tail is longer than in summer. There are a number of races differing in plumage shade. The endemic race in Sri Lanka retains summer plumage, including the shorter tail, all year round.

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 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 Malaysian pied fantail (Rhipidura javanica) is a species of bird in the fantail family and one of 47 species in the genus Rhipidura. It is locally referred to as murai gila, literally "crazy thrush" in the Malay language. It is found in Brunei, Cambodia, Indonesia, Laos, Malaysia, Myanmar, Philippines, Singapore, Thailand, and Vietnam. Its natural habitat is subtropical or tropical moist lowland forests. A single sight was recorded from Yala National Park of south Sri Lanka.

It is black with elongated forehead feathers, forming a frontal crest that may curl backwards. Its beak and feet are yellow. It has white from the vent to the tip of the tail and a white wing patch.

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 common Tailorbird is famous for its nests, which are leaves that have been sewn together. Also known as Orthotomus sutorius, it is found across tropical regions in Asia and can be identified by its long, erect tail. The male and female take care of the chicks, and there have been recorded cases of a pair adopting chicks from another couple.

A familiar sight in rural and semi-open areas, the small barn Swallow can often be spotted by its distinctly graceful flight as it travels low over fields. Seemingly unbothered by having human neighbors, they nest unafraid in barns, garages, beneath bridges or wharves. Interestingly enough, they have come to prefer these locations so much that you are unlikely to spot a nest in a place that is not a human-made structure.

The yellow-bellied prinia (Prinia flaviventris) is a species of bird in the family Cisticolidae. It is found in Pakistan, the southern Himalayan foothills, the northeastern Indian subcontinent, and Southeast Asia.

This swiftlet is 12 cm long and weighs 13 to 14 grams. The plumage is blackish-brown above, but much paler on the underparts. The tail is slightly forked and the wings are long and narrow. The bill and feet are black. The nominate subspecies C. g. germani from Hainan south to Thailand and northern Malaysia has a whitish rump, but C. g. amechanus of the rest of Malaysia has a grey rump. These two forms are sometimes considered to be subspecies of the edible-nest swiftlet. Several calls are uttered including a loud zwing and various chip calls used for echolocation in dark caves. Himalayan swiftlet winters within the range of Germain's swiftlet, but is larger and bulkier, and has a greyer rump than C. g. germani.

The Asian openbill stork is predominantly greyish (non-breeding season) or white (breeding season) with glossy black wings and tail that have a green or purple sheen. The name is derived from the distinctive gap formed between the recurved lower and arched upper mandible of the beak in adult birds. Young birds do not have this gap. The cutting edges of the mandible have a fine brush like structure that is thought to give them better grip on the shells of snails. The tail consists of twelve feathers and the preen gland has a tuft. The mantle is black and the bill is horn-grey. At a distance, they can appear somewhat like a white stork or Oriental stork. The short legs are pinkish to grey, reddish prior to breeding. Non-breeding birds have a smoky grey wings and back instead of white. Young birds are brownish-grey and have a brownish mantle. Like other storks, the Asian openbill is a broad-winged soaring bird, which relies on moving between thermals of hot air for sustained flight. They are usually found in flocks but single birds are not uncommon. Like all storks, it flies with its neck outstretched. It is relatively small for a stork and stands at 68 cm height (81 cm long).

The common Myna is a large, stocky starling that prefers to live near humans in towns and suburban areas. It forages among tall grasses for grasshoppers; in fact, its scientific name, Acridotheres tristis, means "grasshopper hunter." The common Myna likes to maintain two roosts at the same time - both a temporary summer roost near the breeding site as well as a year-round roost where the female can sit and brood.

The Asian palm swift (Cypsiurus balasiensis) is a small swift. It is very similar to the African palm swift, Cypsiurus parvus, and was formerly considered to be the same species. It is a common resident breeder in tropical Asia from India to the Philippines. The down and feather nest is glued to the underside of a palm leaf with saliva, which is also used to secure the usually two or three eggs. This is a bird of open country and cultivation, which is strongly associated with oil palms. This 13 cm long species is mainly pale brown in colour. It has long swept-back wings that resemble a crescent or a boomerang. The body is slender, and the tail is long and deeply forked, although it is usually held closed. The call is a loud shrill scream. Sexes are similar, and young birds differ from adults mainly in their shorter tails. Asian palm swift has very short legs which it uses only for clinging to vertical surfaces, since swifts never settle voluntarily on the ground. These swifts spend most of their lives in the air, living on the insects they catch in their beaks. Asian palm swifts often feed near the ground, and they drink on the wing.

This is a large pipit at 15 cm, but is otherwise an undistinguished looking bird, mainly streaked grey-brown above and pale below with breast streaking. It is long legged with a long tail and a long dark bill. Sexes are similar. Summer and winter plumages are similar. Young birds are more richly coloured below than adults and have the pale edges to the feathers of the upper parts more conspicuous with more prominent spotting on the breast. The population waitei from north-western India and Pakistan is pale while the population malayensis from the Western Ghats is larger, darker and more heavily streaked with the nominate rufulus intermediate. In winter some care must be taken to distinguish this from other pipits that winter in the area, such as Richard's pipit, Anthus richardi and Blyth's pipit, Anthus godlewskii. The paddyfield pipit is smaller and dumpier, has a shorter looking tail and has weaker fluttering flight. The usually uttered characteristic chip-chip-chip call is quite different from usual calls of Richard's pipit (an explosive shreep) and Blyth's pipit (a nasal pschreen). The tawny pipit has less streaking on the mantle and has a black loreal stripe and a longer tail. The Western Ghats population can appear very similar to the Nilgiri pipit.

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.

This shrike is mainly brown on the upper parts and the tail is rounded. The black mask can be paler in winter and has a white brow over it. The underside is creamy with rufous flanks and belly. The wings are brown and lack any white "mirror" patches. Females tend to have fine scalloping on the underside and the mask is dark brown and not as well marked as in the male. The distinction is not easy to use in the field but has been tested with breeding birds in Japan where the female can be identified from the presence of a brood patch. The use of multiple measurements allows discrimination of the sex of about 90% of the birds. Subspecies lucionensis has a grey crown shading into the brown upperparts and the rump appears more rufous than the rest of the upper back. The tail is more brownish and not as reddish as in the red-backed shrike. Younger birds of lucionensis have a brown crown and lack the grey on the head. Subspecies superciliosus has a broad white supercilium and a richer reddish crown. The tail is redder and tipped in white. A number of confusing forms are known from central Asia where the populations of cristatus, isabellinus and collurio overlap. The taxonomy has been in a state of flux and some forms such as phoenicuroides formerly considered as subspecies of L. cristatus have been moved to the species L. isabellinus. Subspecies lucionensis has been recorded interbreeding with superciliosus in Ishikawa, Japan while superciliosus has interbred with Lanius tigrinus in central Japan.

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 Chinese pond heron is typically 47 cm (19 in) long with white wings, a yellow bill with a black tip, yellow eyes and legs. Its overall colour is red, blue and white during breeding season, and greyish-brown and flecked with white at other times. It is found in shallow fresh and salt water wetlands and ponds in China and adjacent temperate and subtropical East Asia. Essentially a lowland bird, its range is delimited by the subarctic regions in the north, and by the mountain ranges in the west and south. The species is prone to some vagrancy. One individual in breeding plumage was seen by the river at Bonzon near Gangaw – just inside the Chin State of Burma – west of the species' usual range, on April 8, 1995. A stray bird stopping over on Saint Paul Island, Alaska on August 4–9, 1997 was the first recorded occurrence of this species in North America. Its food consists of insects, fish, and crustaceans. The Chinese pond heron often nests in mixed-species heronries. It lays a clutch of 3–6 blue-green eggs. It is fairly common and not considered a threatened species by the IUCN.

The dusky warbler (Phylloscopus fuscatus) is a leaf warbler which breeds in the east Palearctic. The genus name Phylloscopus is from Ancient Greek phullon, "leaf", and skopos, "seeker" (from skopeo, "to watch"). The specific fuscatus is from Latin fuscus "dark". This warbler is strongly migratory and winters in South Asia and South-east Asia. It sometimes occurs in North America in Alaska, and has also occurred in California. This is an abundant bird of taiga bogs and wet meadows. The nest is built low in a bush, and 5-6 eggs are laid. Like most Old World warblers, this small passerine is insectivorous. The dusky warbler is prone to vagrancy as far as western Europe in October, despite a 3000 km distance from its breeding grounds. It has wintered in Great Britain. This is a warbler similar in size and shape to a chiffchaff. The adult has an unstreaked brown back and buff underparts. There is a prominent whitish supercilium, and the bill is fine and pointed. The sexes are identical, as with most warblers, but young birds are more olive-tinged above. Like most warblers, it is insectivorous, but will take other small food items, including berries. The song is a monotonous whistle, and the call is a harsh check. The call is often the first clue that this typically skulking species is present, away from the breeding grounds.

These 11-to-13-centimetre (4 to 5 in) long warblers have a longish grey tail with graduated feathers that are tipped in white, they have strong pinkish legs and a short black bill. The eye ring is orange. The sexes look alike in most populations except in P .h. pectoralis of Sri Lanka where the female can be told apart by the incomplete breast band. The underparts are buff white and the grey breast band contrasts with the white throat in the breeding season. They have a rufous wing panel and the upperparts are smoky grey during the breeding season and olive brown in the non-breeding period. Non-breeding birds have a short indistinct white supercilium and often lack the breast band. Young birds are like non-breeding adults but more rufous above. The distinctive greyer endemic race in Sri Lanka, P. h. pectoralis, retains the summer-type plumage all year round. Young birds have a pale lower mandible. The tail feathers are shorter in summer than in the non-breeding winter plumage.
