Top 20 Most Common Bird in Jeju

The brown-eared Bulbul’s loud cry isn’t the only trait that makes it easy to recognize in rural and suburban habitats. Along with its loud, shrill calls, the songbird has an undulating flight pattern, that makes it easy to distinguish from other species. The bird feeds primarily on insects but will also drink Camellia flower nectar, aiding in pollination.

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 oriental Turtle-dove is a migratory bird whose appearance can vary between subspecies. Individuals from higher latitudes migrate south over the winter months while those at lower latitudes do not migrate. The oriental Turtle-dove can be found in a large range of habitats, but usually prefers dense tree coverage. These birds mainly forage for seeds on the ground.

The warbling white-eye is olive green on its back, from anterior to posterior, and is pale green on its underside. Its feet, legs, and bill range from black to brown. It has a green forehead and a yellow throat. The white-eye has rounded wings and a long, slender bill – both of which indicate this bird to be very acrobatic. Its wings are dark brown, but outlined in green. Like other white-eyes, this species exhibits the distinctive white eyering that gives it its name.

The japanese Tit is a large bird for its species, it is also extremely vocal with its loud chirps and song. While it can be seen in parks, it prefers wooded habitats. The songbird made headlines when researchers noticed the syntax in its calls. The bird will even respond to other species if they follow the alert call.

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 Japanese bush warbler is olive brown above and tending toward dusky colors below. It has pale eyebrows. It has a beak that curves up making it look like it is smiling. The bird is typically 15.5 centimetres (6.1 in) in length.

The overall size (length: 46–59 cm; 18–23 in.) and body proportions vary regionally. In the far northeast in Japan, the Kuriles and the Sakhalin peninsula, it is somewhat larger than the carrion crow. All taxa have a relatively long bill with the upper one quite thick and arched, making it look heavy and almost raven-like. Generally, all taxa have dark greyish plumage from the back of the head, neck, shoulders and lower body. Their wings, tail, face, and throat are glossy black. The depth of the grey shading varies across its range.

The grey-capped Greenfinch is a friendly bird that likes to twitter while flying. The finch is often seen in woodlands and its yellow feathers distinguish it from other species. The small songbird feeds on seeds, often found on the ground. However, it also eats insects and small invertebrates in the summer.

The white Wagtail is the national bird of Latvia and is featured in traditional folk songs and placed on some postage stamps. These birds can be found in most habitat types besides deserts. As their name suggests, they exhibit a characteristic tail-wagging behavior as they search along the ground and nearby waterways for insects to eat.

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 bull-headed shrike (Lanius bucephalus) is a passerine bird of eastern Asia belonging to the shrike family Laniidae. It is 19–20 cm (approx. 7.48-7.9 inches) long. The male has a brown crown, white eyebrow and black mask. The back is grey-brown while the wings are dark with a white patch. The flanks are rufous and the rest of the underparts are whitish with fine barring. Females are similar but duller and browner with a brown mask and no white wing-patch. The species has harsh grating and chattering calls and will also mimic other birds. It breeds in north-east China, Korea, Japan and far-eastern Russia (Ussuriland, Sakhalin and the Kuril Islands). Northern birds migrate south for the winter with a few reaching southern China. Vagrants have been recorded in Taiwan, Hong Kong and Vietnam. The isolated race sicarius is found only in the mountains of Gansu Province in west-central China. Open habitats such as farmland and woodland edges are preferred. It also visits parks and gardens in urban areas. It sits on a prominent perch, waiting for prey to pass by. It feeds mainly on insects such as beetles and crickets but also preys on lizards and crustaceans. With some other species from the Lanius genus, like the great grey shrike (Lanius excubitor), the bull-headed shrike is known to impale some of its preys upon a sharp point – usually thorns – so the food can be ripped into bite-sized pieces more easily. It may also do this to cache food and to mark a territory boundary. The nest is built among bushes or bamboo. Two to six eggs are laid. They are incubated for 14 to 15 days and the young birds fledge 14 days after hatching.

The blue Rock Thrush emits a sound similar to a blackbird. It has a wide range, including urban areas, sea cliffs, and mountainsides. The thrush has a unique claim to fame. It is the official bird of Malta and is present on some of the country’s former currencies.

The grey Heron is a very common species to come across in marine, brackish, and freshwater ecosystems; these habitats must have at least four months of warm weather or else these birds will migrate for new breeding grounds. The grey Heron hunts by wading through shallow waters looking for fish and various invertebrates; their natural diet helps control some aquatic species populations.

The omnivorous ring-necked Pheasant sports a distinctive ringed neck. It has been taken from its native East Asia and introduced around the world with positive results. The beauty of the males, with their blue-green heads and red wattles, has made them a popular target for game hunters who mount them as trophies.

The daurian Redstart is an active songbird seen in a variety of habitats. It breeds in open forests and prefers spending the winter in fields and gardens. It is a widespread species of bird across most of Asia, extending into Russia, with a curious personality that often allows humans to get close to the bird before it takes flight.

The black-tailed gull is medium-sized (46 cm), with a wingspan of 126–128 cm. It has yellow legs and a red and black spot at the end of the bill. Males and females have identical plumage and features, although males are larger in size than females. This gull takes four years to reach full adult plumage. As the name suggests, it has a black tail. The bird has a cat-like call, giving it its Japanese name — umineko (海猫, "sea cat"), and Korean name — gwaeng-yi gull, which means "cat" gull. In Hachinohe they are one of the 100 Soundscapes of Japan.

This duck is around the same size as a mallard and has a scaly patterned body with a green speculum bordered by white. At rest the white stripe stands out and the long neck and the bill with yellow tip and orange red spots at the base are distinctive in the nominate subspecies. The red spots at the base of the bills are absent in haringtoni. It measures 55–63 cm (22–25 in) in length and 83–95 cm (33–37 in) across the wings, with a body mass of 790–1,500 g (1.74–3.31 lb). These are mainly grey ducks with a paler head and neck and a black bill tipped bright yellow. The wings are whitish with black flight feathers below, and from above show a white-bordered green The male has a red spot on the base of the bill, which is absent or inconspicuous in the smaller but otherwise similar female. The male does not have an eclipse plumage. The legs and feet are bright orange to coral red. Juveniles are browner and duller than adults. The eastern spot-billed duck is darker and browner; its body plumage is more similar to the Pacific black duck. It lacks the red bill spot, and has a blue speculum. Both males and females undergo a complete post-breeding moult, dropping all their wing feathers simultaneously.

The meadow Bunting is often described as a handsome bird due to the distinctive coloring on its face. It is a talkative bird, giving multiple calls instead of single chirps. The best place to spot the large bunting is in open areas with plenty of vegetation like meadows, forest edges, and agricultural fields.

While the common Sandpiper is considered a common shorebird around lakes and rivers, it does have a unique trait. The small bird bobs its tail, giving the appearance of wagging. The bird communicates with others by chirping in the air, but is silent when feeding on small crustaceans and invertebrates.
