Bangladeshi Birds

Mynah

 

The myna or mynah is a bird of the starling family (Sturnidae). This is a group of passerine birds which occur naturally only in southern and eastern Asia, especially in North India. Several species have been introduced to areas like North America, Australia, South Africa and New Zealand, especially the Common Myna which is often regarded as an invasive species.

Mynas are not a natural group (Zuccon et al. 2006); instead, the term myna is used for any starling in India and surrounding areas, regardless of their relationships. This range was colonized twice during the evolution of starlings, first by rather ancestral starlings related to the Coleto and Aplonis lineages, and millions of years later by birds related to the Common Starling and Wattled Starling's ancestors. These two groups of mynas can be distinguished in the more terrestrial adaptions of the latter, which usually also have less glossy plumage except on the heads and longer tails. The Bali Myna which is nearly extinct in the wild is highly distinctive.

Pegions 

Pigeons and doves constitute the bird clade Columbidae that include some 310 species of near passerines. In general the terms "dove" and "pigeon" are used somewhat interchangeably. In ornithological practice, there is a tendency for "dove" to be used for smaller species and "pigeon" for larger ones, but this is in no way consistently applied, and historically the common names for these birds involve a great deal of variation between the terms "dove" and "pigeon." This family occurs worldwide, but the greatest variety is in the Indomalaya and Australasia ecozones. Young doves and pigeons are called "squabs."

Pigeons and doves are stout-bodied birds with short necks, and have short slender bills with a fleshy cere. The species commonly referred to just as "pigeon" is the Feral Rock Pigeon, common in many cities.
Doves and pigeons build relatively flimsy nests from sticks and other debris, which may be placed in trees, on ledges or on the ground, depending on species. They lay one or two eggs, and both parents care for the young, which leave the nest after 7 to 28 days.^[1] Doves feed on seeds, fruit and plants. Unlike most other birds (but see flamingo), the doves and pigeons produce "crop milk", which is secreted by a sloughing of fluid-filled cells from the lining of the crop. Both sexes produce this highly nutritious substance to feed to the young.

 

Magpie

According to analysis,^[3] magpies do not form the monophyletic group they are traditionally believed to be—a long tail has certainly elongated (or shortened) independently in multiple lineages of corvid birds. Among the traditional magpies, there appear to be two distinct lineages: one consists of Holarctic species with black/white coloration and is probably closely related to crows and Eurasian jays. The other contains several species from South to East Asia with vivid coloration which is predominantly green or blue. The Azure-winged Magpie is a species with a most peculiar distribution and unclear relationships. It may be the single survivor of a long extinct group of corvid genera.^{[citation needed]}

  

 Other research^[4] has cast doubt on the taxonomy of the Pica magpies, since it appears that P. hudsonia and P. nuttalli may not be different species, whereas the Korean race of P. pica is genetically very distinct from the other Eurasian (as well as the North American) forms. Either the North American, Korean, and remaining Eurasian forms are accepted as three or four separate species, or there exists only a single species, Pica pica

Kingfisher

Kingfishers are a group of small to medium sized brightly coloured birds in the order Coraciiformes. They have a cosmopolitan distribution, with most species being found in the Old World and Australasia. The group is treated either as a single family, Alcedinidae, or as a suborder Alcedines containing three families, Alcedinidae (river kingfishers), Halcyonidae (tree kingfishers), and Cerylidae (water kingfishers). There are roughly 90 species of kingfisher. All have large heads, long, sharp, pointed bills, short legs, and stubby tails. Most species have bright plumage with little differences between the sexes.

 Most species are tropical in distribution, and a slight majority are found only in forests. They consume a wide range of prey as well as fish, usually caught by swooping down from a perch. Like other members of their order they nest in cavities, usually tunnels dug into the natural or artificial banks in the ground. A few species, principally insular forms, are threatened with extinction

 

Little Egret

The adult Little Egret is 55–65 cm long with an 88–106 cm wingspan, and weighs 350–550 grams. Its plumage is all white. The subspecies garzetta has long black legs with yellow feet and a slim black bill. In the breeding season, the adult has two long nape plumes and gauzy plumes on the back and breast, and the bare skin between the bill and eyes becomes red or blue. Juveniles are similar to non-breeding adults but have greenish-black legs and duller yellow feet. has yellow feet and a bare patch of grey-green skin between the bill and eyes. The subspecies nigripes differs in having yellow skin between the bill and eye, and blackish feet.

Little Egrets are mostly silent but make various croaking and bubbling calls at their breeding colonies and produce a harsh alarm call when disturbed
