7-3-2020 PERIYAR, INDIA - WHITE BROWED WAGTAIL (Motacilla maderaspatensis)
The white-browed wagtail or large pied wagtail (Motacilla maderaspatensis) is a medium-sized bird and is the largest member of the wagtail family. They are conspicuously patterned with black above and white below, a prominent white brow, shoulder stripe and outer tail feathers. White-browed wagtails are native to South Asia, common near small water bodies and have adapted to urban environments where they often nest on roof tops. The specific name is derived from the Indian city of Madras (now Chennai).

The white-browed wagtail is the largest species of wagtail at 21 cm (8.3 in) length. It is a slender bird, with the characteristic long, constantly wagging tail of its genus. It has black upperparts, head and breast, with a white supercilium and large white wingbar. Unlike white wagtails it never has white on the forehead. The rest of the underparts are white. The female has the black less intense than in the male. Juveniles are like the females brown-grey where the adult is black.

The white-browed wagtail is a resident breeder in India and is endemic to the Indian subcontinent. It is found south of the Himalayas, east of the Indus system and to the west of Bangladesh. It is rare in the higher altitude regions but has been seen in Ladakh on the edge of the Tibetan plateau. In most of India it is found below 1000 m but in southern India it goes up into the hills up to 2200 m. It is very rare in the Indus valley area. It is absent from the Sind region of Pakistan. It is found in open freshwater wetland habitats. It is one of the few Motacilla wagtails that has adapted well to urban habitats and is often found perched on overhead water storages in residential buildings.
It is a rare winter visitor to Sri Lanka and have possibly extended their range in recent times.

Usually seen in pairs or small groups near open water. They call often especially in the mornings and are active like most other wagtails. They will perch on the ground as well as on wires or on buildings. The song is long and loud with many different notes. The usual call is a wheezy "wheech". They can fly fairly rapidly for long distances and they fly with a bounding (dipping and rising) flight pattern and have been recorded to travel at the speed of about 40 km/h.
Endoparasitic filarial parasites of the species Splendidofilaria singhi have been recorded in individuals of the species.

8-3-2020 THATTEKAD, INDIA - CHESTNUT HEADED BEE-EATER (Merops leschenaulti)
The chestnut-headed bee-eater (Merops leschenaulti), or bay-headed bee-eater, is a near passerine bird in the bee-eater family Meropidae. It is a resident breeder in the Indian subcontinent and adjoining regions, ranging from India east to Southeast Asia.
This species, like other bee-eaters, is a richly coloured, slender bird. It is predominantly green, with blue on the rump and lower belly. Its face and throat are yellow with a black eye stripe, and the crown and nape are rich chestnut. The thin curved bill is black. Sexes are alike, but young birds are duller.
This species is 18–20 cm long; it lacks the two elongated central tail feathers possessed by most of its relatives.
8-3-2020 THATTEKAD, INDIA - BRAHMINY STARLING (Sturnia pagodarum)
The brahminy starling or brahminy myna (Sturnia pagodarum) is a member of the starling family of birds. It is usually seen in pairs or small flocks in open habitats on the plains of the Indian subcontinent.
It is a resident breeder in Nepal and India, a winter visitor to Sri Lanka and a summer visitor in parts of the western and northeastern Himalayas. They are spotted in the plains of Pakistan as well. They have musical call notes that are long, made up of a series of slurred notes that end abruptly. Although mainly seen on the plains, there are a few records from above 3,000m, mainly from Ladakh.
This passerine is typically found in dry forest, scrub jungle and cultivation and is often found close to human habitations. They especially favour areas with waterlogged or marshy lands.
8-3-2020 THATTEKAD, INDIA - COMMON IORA (Aegithina tiphia)
The common iora (Aegithina tiphia) is a small passerine bird found across the tropical Indian subcontinent and Southeast Asia, with populations showing plumage variations, some of which are designated as subspecies. A species found in scrub and forest, it is easily detected from its loud whistles and the bright colours. During the breeding season, males display by fluffing up their feathers and spiral in the air appearing like a green, black, yellow, and white ball.
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).
Ioras forage in trees in small groups, gleaning among the branches for insects. They sometimes join mixed species feeding flocks. The call is a mixture of churrs, chattering and whistles, and the song is a trilled wheeeee-tee. They may sometimes imitate the calls of other birds such as drongos.
During the breeding season, mainly after the monsoons, the male performs an acrobatic courtship display, darting up into the air fluffing up all his feathers, especially those on the pale green rump, then spiralling down to the original perch. Once he lands, he spreads his tail and droops his wings. Two to four greenish white eggs are laid in a small and compact cup-shaped nest made out of grass and bound with cobwebs and placed in the fork of a tree. Both male and female incubate and eggs hatch after about 14 days. Nests predators include snakes, lizards, crow-pheasant and crows. Nests may also be brood-parasitized by the banded bay cuckoo.
Ioras moult twice in a year and the plumage variation makes them somewhat complicated for plumage based separation of the populations.
