Green bee-eater

The Green Bee-eater (Merops orientalis) (sometimes Little Green Bee-eater) is a near passerine bird in the bee-eater family. It is resident but prone to seasonal movements and is found widely distributed across sub-Saharan Africa from Senegal and the Gambia to Ethiopia, the Nile valley, western Arabia and Asia through India to Vietnam. They are mainly insect eaters and they are found in grassland, thin scrub and forest often quite far from water. Several regional plumage variations are known and several subspecies have been named.

Like other bee-eaters, this species is a richly coloured, slender bird. It is about 9 inches (16–18 cm) long with about 2 inches made up by the elongated central tail-feathers. The sexes are not visually distinguishable. The entire plumage is bright green and tinged with blue especially on the chin and throat. The crown and upper back are tinged with golden rufous. The flight feathers are rufous washed with green and tipped with blackish. A fine black line runs in front of and behind the eye. The iris is crimson and the bill is black while the legs are dark grey. The feet are weak with the three toes joined at the base.Southeast Asian birds have rufous crown and face, and green underparts, whereas Arabian beludschicus has a green crown, blue face and bluish underparts. The wings are green and the beak is black. The elongated tail feathers are absent in juveniles. Sexes are alike.

The calls is a nasal trill tree-tree-tree-tree, usually given in flight.They are mostly see in the plains but can sometimes be found up to 5000 or 6000 feet in the Himalayas. They are resident in the lowlands of South Asia but some populations move seasonally but the patterns are not clear,^[3] moving away to drier regions in the rainy season and to warmer regions in winter.In parts of Pakistan, they are summer visitors.

Like other species in the genus, bee-eaters predominantly eat insects, especially bees, wasps and ants.They are usually seen in small groups and often roost communally in large numbers (200-300). The birds move excitedly at the roost site and call loudly, often explosively dispersing before settling back to the roost tree. The breeding season is from March to June. Unlike many bee-eaters, these are often solitary nesters, making a tunnel in a sandy bank.The nest tunnel that they construct can run as much as 5 feet long and the 3-5 eggs are laid on the bare ground in the cavity at the end of the tunnel. The eggs are very spherical and glossy white.

Yellow-wattled lapwing - Endemic to Indian Sub Continent

The yellow-wattled lapwing (Vanellus malabaricus) is a lapwing that is endemic to the Indian Subcontinent. It is found mainly on the dry plains of peninsular India and has a sharp call and is capable of fast flight. Although they do not migrate, they are known to make seasonal movements in response to rains. They are dull grey brown with a black cap, yellow legs and a triangular wattle at the base of the beak. Like other lapwings and plovers, they are ground birds and their nest is a mere collection of tiny pebbles within which their well camouflaged eggs are laid. The chicks are nidifugous, leaving the nest shortly after hatching and following their parents to forage for food.

These are conspicuous and unmistakable birds found in dry stony and open grassland or scrub habitats. They are medium-sized pale brown waders with a black crown which is separated from the brown on the neck by a narrow white band and large yellow facial wattles. The chin and throat are black and the brown neck and upper breast is separated from the white belly by a narrow blackish line. The tail has a subterminal black band which does not extend into the outer tail-feathers. There is a white wingbar on the inner half of the wing. The bill is yellow at the base. They have tiny yellow carpal spurs. The crown feathers can be raised slightly in displays. They are mostly sedentary but populations make long distance movements in response to the monsoons. They are occasional visitors to the Katmandu valley in Nepal.

There are no recognized subspecies, but there is a size increase from south to north. They are 260-280mm long with a wing of 192-211mm, bill 23-26mm, tarsus 57-66mm and tail 71-84mm. Juveniles have a brown crown and the sexes are alike but males have slightly longer wings and tarsi. The call is a sharp tchee-it call.

Local names include zirdi in Hindi, chitawa in Telugu and jithiri in Rajasthan and Pakistan, pili tatihri in Punjabi, laori in Madhya Pradesh,parasna titodi or vagdau titodi in Gujarati, pitmukhi titvi in Marathi, manjakanni in Malayalam, haladi tittibha in Kannada, aalkati in Tamil andkiraluwa in Sinhalese.

This species is common in much of India, being seen in a variety of open lowland habitats. It tends to be seen in drier habitats than the red-wattled lapwing, Vanellus indicus. They are found in most parts of India, parts of Pakistan,Nepal, Bangladesh and Sri Lanka. They make short distance movements in response to rain but the exact pattern is not known.

These lapwings breed in the dry season with peak breeding in March to May ahead of the monsoons. They lay four eggs in a ground scrape. A nest in a clump of grass has been noted as exceptional.

Pied Kingfisher - Resident Breeder in Sri Lanka

The pied kingfisher (Ceryle rudis) is a water kingfisher and is found widely distributed across Africa and Asia. Its black and white plumage, crest and the habit of hovering over clear lakes and rivers before diving for fish makes it distinctive. Males have a double band across the breast while females have a single gorget that is often broken in the middle. They are usually found in pairs or small family parties. When perched, they often bob their head and flick up their tail.

This kingfisher is about 17 cm long and is white with a black mask, a white supercilium and black breast bands. The crest is neat and the upperparts are barred in black. Several subspecies are recognized within the broad distribution. The nominate race is found in sub-Saharan Africa, extending into West Asia. A former subspecies syriaca is considered as merely a larger northern bird of the nominate species. Subspecies leucomelanura is found from Afghanistan east into India, Sri Lanka, Thailand and Laos. The subspecies travancoreensis of the Western Ghats is darker with the white reduced. Subspecies C. r. insignis is found in Hainan and southeastern China and has a much larger bill. Males have a narrow second breast-band while females have a single broken breast band.

It is common throughout sub-Saharan Africa and southern Asia from Turkey to India to China. It is resident, and most birds do not migrate, other than short-distance seasonal movements. In India it is distributed mainly on the plains and is replaced in the higher hills of the Himalayas by Megaceryle lugubris.

This kingfisher feeds mainly on fish, although it will take crustaceans and large aquatic insects such as dragonfly larvae. It usually hunts by hovering over the water to detect prey and diving vertically down bill-first to capture fish. When not foraging, they have a straight rapid flight and have been observed flying at nearly 32 mph.In Lake Victoria in East Africa the introduction of the Nile perch reduced the availability of haplochromine cichlids which were formerly the preferred prey of these birds.

They can deal with prey without returning to a perch, often swallowing small prey in flight, and so can hunt over large water bodies or in estuaries that lack perches that are required by other kingfishers. Unlike some kingfishers, it is quite gregarious, and forms large roosts at night.When perched, the often bob their heads up and down and will sometimes raise their tail and flick it downwards. They call often with sharpchirruk chirruk notes.

The breeding season is February to April. Its nest is a hole excavated in a vertical mud bank about five feet above water. The nest tunnel is 4 to 5 feet deep and ends in a chamber. Several birds may nest in the same vicinity. The usual clutch is 3–6 white eggs.he pied kingfisher sometimes reproduces co-operatively, with young non-breeding birds from an earlier brood assisting parents or even unrelated older birds.In India, nestings have been found to be prone to maggot infestations (probably by Protocalliphora sp.). and in some areas to leeches. Nest holes may sometimes be used for roosting.

Oriental Darter/ Indian Darter - Resident Breeder in Sri Lanka

The Oriental darter or Indian darter (Anhinga melanogaster ) is a water bird of tropical South Asia and Southeast Asia. It has a long and slender neck with a straight, pointed bill and, like the cormorant, it hunts for fish while its body submerged is in water. It spears a fish underwater, brings it to the surface and tosses it into the air before swallowing it. The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for its other name: snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry.

The Oriental darter is like all other anhingas, a cormorant-like species that has a very long neck. The structure of the neck is as in other species of darter with strongly developed muscles about a kink in the neck at the 8th and 9th vertebrae that allows it to be flexed and darted forward with rapid force to stab fish underwater. The edges of the commisures of the mandible tips have minute inward pointing serrations that hold impaled fish.

The adult plumage above is black and the wing coverts and tertials having silvery streaks along the shaft. The crown and neck are brown shading to black towards the back of the neck. The underparts are blackish brown. A pale line over the eye and throat and a line running along the sides of the neck gives it a striped appearance. The iris is white with a yellow ring around it. The tip of the upper mandible is dark while the base is pale brown bill while the lower mandible is yellowish. The legs and webbing on the foot are yellow in immatures and dark grey in older birds.The sexes are not easily distinguishable but males tend to have black speckles that coalesce on the white throat.Adult females have a shorter bill and tend to have the black at the base of neck and chest separated from the hind neck by a wide buff band that ends at the shoulder. This pattern however is also found in immatures whose neck is lighter and lack the long pointed scapulars.In flight the long and slender neck, wide wing and wedge shaped tail make it distinctive.Young birds have a pale brown neck and appear whitish on the underside and lack the white streak along the side of the neck. The inner secondaries or tertials and the central tail feathers appear wavy or corrugated.The tail is long and made up of twelve stiff feathers which are dragged along the ground when the bird attempts to walk or hop on land.

Common Moorhen - Resident breeder in Sri Lanka

The Common Moorhen (Gallinula chloropus) (also known as the "swamp chicken") is bird species in the Rallidae family. It is distributed across many parts of Africa, Europe & Asia. 

The Common Moorhen lives around well-vegetated marshes, ponds, canals and other wetlands. The species is not found in the polar regions or many tropical rainforests. Elsewhere it is likely the most common rail species, except for the Eurasian Coot in some regions.

The Moorhen is a distinctive species, with dark plumage apart from the white undertail, yellow legs and a red frontal shield. The young are browner and lack the red shield. The frontal shield of the adult has a rounded top and fairly parallel sides; the tailward margin of the red unfeathered area is a smooth waving line. In the related Common Gallinule of the Americas, the frontal shield has a fairly straight top and is less wide towards the bill, giving a marked indentation to the back margin of the red area.

The Common Moorhen gives a wide range of gargling calls and will emit loud hisses when threatened.A mid-sized to large rail, it can range from 30 to 38 cm (12 to 15 in) in length and span 50 to 62 cm (20 to 24 in) across the wings. The body mass of this species can range from 192 to 500 g (6.8 to 17.6 oz).

This is a common breeding bird in marsh environments and well-vegetated lakes. Populations in areas where the waters freeze, such as eastern Europe, will migrate to more temperate climes. This species will consume a wide variety of vegetable material and small aquatic creatures. They forage beside or in the water, sometimes walking on lilypads or upending in the water to feed. They are often secretive, but can become tame in some areas. Despite loss of habitat in parts of its range, the Common Moorhen remains plentiful and widespread.

The birds are territorial during breeding season. The nest is a basket built on the ground in dense vegetation. Laying starts in spring, between mid-March and mid-May in N hemisphere temperate regions. About 8 eggs are usually laid per female early in the season; a brood later in the year usually has only 5–8 or fewer eggs. Nests may be re-used by different females. Incubation lasts about three weeks. Both parents incubate and feed the young. These fledge after 40–50 days, become independent usually a few weeks thereafter, and may raise their first brood the next spring. When threatened, the young may cling to the parents' body, after which the adult birds fly away to safety, carrying their offspring with them.
