  • Leafbirds – Golden-fronted leafbird

    Golden frontend Leafbird

    The Golden-fronted Leafbirds (Chloropsis aurifrons) are common resident breeder in India, Sri Lanka, and parts of Southeast Asia. They inhabit in deciduous monsoon forests and scrublands.

    Leafbirds were named for the fact that their mostly green and yellow plumages blend in well into their tropical habitat, where the green leaves and bright flowers of the canopy provide a perfect camouflage for these birds. However, leafbirds that are stressed will shed most of their colorful feathers. This adaptation may have evolved as a way of confusing predators, such as snakes. Captured birds under stress will do the same.

    DESCRIPTION

    The adult is green-bodied with a black face and throat bordered with yellow. It has an orange forehead and blue moustachial line, Young birds have a plain green head. Immature birds look like duller versions of the females.
    They have forked, brush-tipped tongues and fairly hefty, straight to lightly down-curved bills with stiff, hair-like feathers at the base that protect their eyes from the legs and wings of their insect prey.

    NESTING / BREEDING

    Leafbirds build open cup-shaped nests out of fine stems, leaf parts and rootlets. These nests are typically placed on the ends of branches near the tree crown; although some may hang from thin horizontal shoots of trees, or they are attached to a pair of vertical twigs. The average clutch consists of 2 – 3 pinkish eggs. The incubation lasts about 14 days and is performed by the female alone, while the male feeds the brooding female. Even though unconfirmed, it appears likely, that the male also helps raise the young.

    DIET / FEEDING

    Leafbirds typically forage alone or in pairs in the subcanopy; but some species may occasionally join mixed feeding flocks, while other species defend their feeding territories.

    They feed on mostly insects, as well as taking fruits, berries and nectar.

    Insects: Their long sharp beaks are curved down slightly and a brush tipped tongue, helping them to pick insects from the bark and leaves of trees. They will also pursue flushed prey into the air or down to the forest floor.

    Nectar: Their spiked tongues are well adapted for taking nectar from tubular flowers, such as the Rhabdornis of the Philippines. Like hummingbirds, they will hover in front of a flower while retrieving the nectar. In the process of feeding, the flowers benefit from cross-pollination as the leafbird’s head becomes covered with pollen and spreads from flower to flower. As they move to the next flower, the pollen is deposited on the next flower, which is then able to produce seeds and fruit. Many native plants rely on them for pollination and would not be able to exist without the “services” inadvertently rendered by the leafbirds.

    Fruits: Usually, leafbirds swallow pieces of fruit whole. If this isn’t possible, they will pierce the fruits with their beaks and let the juices leak into their mouths.

    Their attractive songs include various melodious whistles and chatters.

  • Leafbirds in India Jerdon’s leaf bird

    The leafbirds (Chloropseidae) are a family of small passerine bird species found in the Indian Subcontinent and Southeast Asia. As presently defined, the leafbird family is monogeneric, with all species placed in the genus Chloropsis.

    leafbirds are brightly plumaged, with the predominant green over the body giving rise to their common name. The family is mostly sexually dimorphic in their plumage, this can vary from the highly dimorphic orange-bellied leafbird to the Philippine leafbird, which exhibits no sexual dimorphism. Most of the differences between the sexes are in the extent of the other colours in the plumage, particularly in the colours around the head and the blue or black face mask, with females have less colour and a less extensive (or absent) mask. Some species have blue on the wings and tail. The plumage of juvenile birds is a duller version of the female’s.

    Most are restricted to evergreen forests except the golden-fronted leafbird and Jerdon’s leafbird which live in deciduous monsoon forests, and the orange-bellied leafbird, which occurs in deciduous forests. Within this requirement, they occupy all broadleaf forest types in the Indian Subcontinent and Southeast Asia. 

    To human ears, their songs are melodious, and several species are good mimics. The calls include whistles and chatters.
    Leafbirds are always found in trees and shrubs.

    They feed on fruits, insects and even nectar.

    There are four species of leafbirds (also known as chloropsis) found in India and they never fail to enthral a birder. Each of them is largely green, slender in build, with a medium-length tail and the habit of dwelling in the top or mid-canopy.

    *The Orange-bellied Leafbird Chloropsis hardwickii is restricted to the lower and middle Himalayas.
    *The Blue-winged Leafbird Chloropsis cochinchinensis is found in the North-eastern lowlands (and further up in the Cachar Hills as well), while the very similar (and recently split from Blue-winged). 
    *Jerdon’s Leafbird Chloropsis jerdoni is found throughout much of the peninsula.
    *The Golden-fronted Leafbird Chloropsis aurifrons is widespread across the entire region, overlapping in range with all the other subcontinental leafbirds.

    Calls

    All leafbirds may sounds extremely similar to the untrained ear. Most calls are a mixture of harsh and sweet notes with some differences in quality. Leafbirds are also excellent mimics and often have an impressive repertoire of sounds that may cause confusion amongst several birders!

    Jerdon’s leafbird (Chloropsis jerdoni) is a species of leafbird found in forest and woodland in India and Sri Lanka. Its name honours Thomas C. Jerdon. It has traditionally been considered a subspecies of the blue-winged leafbird (C. cochinchinensis), but differ in measurements and morphology, it lacking the blue flight feathers for which the blue-winged leafbird was named.

    It builds its nest in a tree, and lays 2–3 eggs. This species eats insects, fruit and nectar.

    The male is green-bodied with a yellow-tinged head, black face and throat. It has a blue moustachial line.

    The female differs in that it has a greener head and blue throat.

    young birds are like the female but without the blue throat patch.

    Like other leafbirds, the call of Jerdon’s leafbird consists of a rich mixture of imitations of the calls of various other species of birds.

  • Yellow-wattled lapwing Vanellus malabaricus Endemic Bird Photos and notes.

    The yellow-wattled lapwing (Vanellus malabaricus) belongs to the family of plovers, dotterels, and lapwings, Charadriidae.

    The yellow-wattled lapwing species are distributed in India, Nepal, Bangladesh, Pakistan and Sri Lanka. These lapwing species are endemic to Indian subcontinent. These lapwings are monotypic species.

    Appearance, physical description and identification

    Appearance, physical description and identification
    The yellow-wattled lapwing (Vanellus malabaricus)
    is a medium-sized wader, measuring 25 to 30 cm in length and weighing 100 to 200 grams. The wingspan is 65 to 70 cm.

    The yellow-wattled lapwing species have the characteristic, prominent triangular yellow facial wattles at the base of the bill and forehead. There is a black or brownish black crown, separated by a border of thin white band. Excited bird can raise crown feathers.

    In these lapwings, the neck and the upperparts are sandy brown. The rump and the tail are white. Excluding the outer tail feathers, there is a subterminal black band on the tail feathers. The breeding yellow-wattled lapwings have black patch on the chin and throat.

    The flight feathers are black and there is a white wing bar on the inner half of the wing. The throat and the upper breast are buff brown. In breeding lapwings, the breast is separated from the white belly by a diffuse blackish band. The rest of the underparts are white.

    The lapwing bill is short and dark gray with yellowish base. The irises are pale brown. The long legs are yellow. The feet extend well beyond the tail while flying. These species do not have hind toes.k

    The juvenile wattled lapwing is a dull version of the adult. The wattle appears small and dull. The chin is white. The cap is pale brown with dark striation. The upperparts may have dark markings.

    The call of these yellow-wattled lapwing species is a descending “ke-oo..ke-oo”, a high pitched repeated “twit.twit.twit” or a sharp “tchee-it” sound.

    Diet and feeding behavior

    The diet of the yellow-wattled lapwing consists mainly of insects. Grasshoppers, crickets, locust, beetles, caterpillars, grubs, mantids, stick insects, spiders, macrobenthic fauna, macrophytes, cereals and grains are their primary food.

    The yellow-wattled lapwing species are mainly terrestrial birds and obligate visual foragers, catching prey from the surface of the ground or from low vegetative cover. The chicks feed on small insects, annelids, cereal, spiders, small frogs, millipedes and small toads.

    Reproduction and breeding habits

    The breeding season of these yellow-wattled lapwing species is from March to May in India. The laying season in Sri Lanka is from March to August. The breeding season is from April to June in Pakistan.

    During courtship, the yellow-wattled lapwing male produces high frequency notes with fully puffed breast. The female in the vicinity responds by repeated short calls. They make fly and dive display, which culminates in mating on the ground.

    These wattled lapwings are monogamous. The male selects the breeding site. The site is usually located on open sparsely vegetated ground in the vicinity of water body. Both the male and female build the nest. The nest is a slight depression on the ground.

    The typical wattled lapwing clutch contains 3-4 eggs. The eggs are soil-brown with black and creamy blotches. Pebbles and soil balls are accumulated from nearby areas and placed in the nest to provide camouflage to the eggs.

    The yellow-wattled lapwing pair take turns to incubate the eggs for about 28 days. Though the eggs are laid with a difference of a few days, hatching is synchronous. The hatchlings are covered with brown black down feathers, providing perfect camouflage.

    The yellow-wattled lapwing hatchlings are nidifugous and leave the nest soon after hatching. The parents feed the chicks with small insects, spiders, millipedes and earthworms. Parental care goes on for nearly one month.

    The breeding yellow-wattled lapwing pair actively defends its territory from other birds. The parents distract the intruders away from the nest. They also defend their nest from stray dogs, shikra and crows. On warning call from parents, the chicks squat and freeze.

    The parent lapwings may soak their breast feathers at the watering hole and, returning to nest, brood to cool the eggs and chicks with water. A second brood may be raised, particularly when the first fails.

    Migration and movement patterns

    The yellow-wattled lapwing species are non-migratory resident birds. They make short distance movements in rainy season. The movement pattern is not clear.
