Top 20 Most Common Bird in Nakhon Si Thammarat

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.

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 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 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 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.

This species is 19 centimetres (7.5 in) long, including the long tail, which is usually held cocked upright when hopping on the ground. When they are singing a song the tail is normal like other birds. It is similar in shape to the smaller European robin, but is longer-tailed. The male has black upperparts, head and throat apart from a white shoulder patch. The underparts and the sides of the long tail are white. Females are greyish black above and greyish white. Young birds have scaly brown upperparts and head. It is the national bird of Bangladesh. The nominate race is found on the Indian subcontinent and the females of this race are the palest. The females of the Andaman Islands race andamanensis are darker, heavier-billed and shorter-tailed. The Sri Lankan race ceylonensis (formerly included with the peninsular Indian populations south of the Kaveri River) and southern nominate individuals have the females nearly identical to the males in shade. The eastern populations (Bhutan and Bangladesh) have more black on the tail and were formerly named erimelas. The populations in Burma and further south are named as the race musicus. A number of other races have been named across the range, including prosthopellus (Hong Kong), nesiotes, zacnecus, nesiarchus, masculus, pagiensis, javensis, problematicus, amoenus, adamsi, pluto, deuteronymus and mindanensis. However, many of these are not well-marked and the status of some of them is disputed. Some, like mindanensis, have now been usually recognized as full species (the Philippine magpie-robin). There is more geographic variation in the plumage of females than in that of the males. It is mostly seen close to the ground, hopping along branches or foraging in leaf-litter on the ground with a cocked tail. Males sing loudly from the top of trees or other high perches during the breeding season.

The Ayeyarwady bulbul (Pycnonotus blanfordi) is a member of the bulbul family of passerine birds. It is endemic to Myanmar. Its natural habitat is subtropical or tropical moist lowland forests. Until 2016, the Ayeyarwady bulbul was considered to be conspecific with the streak-eared bulbul (now Pycnonotus conradi).

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 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 Eudynamys scolopaceus is commonly called asian Koel, native to China, the Indian Subcontinent and parts of Southeast Asia. This bird is used widely in Indian poetry, and it has a habit of colonizing new areas that it goes to. The bird is also known for stealing nests from other birds and having their chicks raised by the foster parents.

The little cormorant is about 50 centimetres (20 in) long and only slightly smaller than the Indian cormorant (Phalacrocorax fuscicollis). The Indian cormorant has a narrower and longer bill which ends in a prominent hook tip, blue iris and a more pointed head profile. The breeding adult bird has a glistening all black plumage with some white spots and filoplumes on the face. There is also a short crest on the back of the head. The eyes, gular skin and face are dark. In the non-breeding bird or juvenile, the plumage is brownish and the bill and gular skin can appear more fleshy. The crest becomes inconspicuous and a small and well-marked white patch on the throat is sometimes visible. Towards the west of the Indus River valley, its range can overlap with vagrant pygmy cormorants (Microcarbo pygmaeus), which can be difficult to differentiate in the field and are sometimes even considered conspecific. The sexes are indistinguishable in the field, but males tend to be larger. Some abnormal silvery-grey plumages have been described. The species was described by Vieillot in 1817 as Hydrocorax niger. The genus Hydrocorax literally means water crow. It was later included with the other cormorants in the genus Phalacrocorax but some studies place the smaller "microcormorants" under the genus Microcarbo.

The purple Heron is a beautiful bird that is highly adapted to its wetland habitat, where it primarily feeds on fish and other prey. Its long neck and sharp beak make it a skilled hunter of fish and small prey in shallow waters. It is easily recognizable.

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 white-throated Kingfisher is a brightly colored bird with a distinctive white throat and blue wings. It inhabits rivers, lakes, and coastal areas, and feeds on a variety of prey such as fish, frogs, and insects. The kingfisher is known for its bold, dive-bombing hunting style, diving from a perch to catch prey in the water. During the breeding season, the White-throated Kingfisher is known for its loud, cackling call. This species is widely distributed across Asia.

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 species is 13 cm (5.1 in) long, including the cocked tail. It is similar in shape to the larger spotted flycatcher, but is relatively longer-tailed. The dark bill is relatively large and broad-based. The adult has grey-brown upperparts, which become greyer as the plumage ages, and whitish underparts with brown-tinged flanks. Young birds have scaly brown upperparts, head and breast.

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 whistling thrush is dark violet blue with shiny spangling on the tips of the body feathers other than on the lores, abdomen and under the tail. The wing coverts are a slightly different shade of blue and the median coverts have white spots at their tips. The bill is yellow and stands in contrast. The inner webs of the flight and tail feathers is black. The sexes are similar in plumage. It measures 31–35 cm (12–14 in) in length. Weight across the subspecies can range from 136 to 231 g (4.8 to 8.1 oz). For comparison, the blue whistling thrush commonly weighs twice as much as an American robin. This species is possibly the largest extant thrush though size overlap does occur with the similar by length great thrush and the insular Amami thrush, whose mean body mass falls around the middle of those of the whistling thrush. Among standard measurements, the wing chord can measure 15.5–20 cm (6.1–7.9 in) long, the tarsus is 4.5–5.5 cm (1.8–2.2 in) and the bill is 2.9–4.6 cm (1.1–1.8 in). Size varies across the range with larger thrushes found to the north of the species range and slightly smaller ones to the south, corresponding with Bergmann's rule. In northern China, males and females average 188 g (6.6 oz) and 171 g (6.0 oz), whereas in India they average 167.5 g (5.91 oz) and 158.5 g (5.59 oz). Several populations are given subspecies status. The nominate form with a black bill is found in central and eastern China. The population in Afghanistan, turkestanicus, is often included in the widespread temminckii which has a smaller bill width at the base and is found along the Himalayas east to northern Burma. The population eugenei, which lacks white spots on the median coverts, is found south into Thailand. Cambodia and the Malay peninsula have crassirostris, while dichrorhynchus with smaller spangles occurs further south and in Sumatra. The Javan population, flavirostris, has the thickest bill. The subspecies status of several populations has been questioned.

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.

Measuring 9 cm (3.5 in) and weighing 7 to 8 grams (0.25 to 0.28 oz), the scarlet-backed flowerpecker is a small bird with a short tail. It exhibits sexual dimorphism. The male has a navy blue face, wings and tail, with a broad bright red stripe from its crown to its upper tail coverts. The female is predominantly olive green with a black tail and scarlet upper tail coverts and rump. Both sexes have creamy white underparts, black eyes and legs, and a dark grey arched bill. The juvenile has plumage similar to the female but has an orange bill and lacks the bright red rump.
