The spot-billed duck species was little frequent at Perumbakkam Marshland and they were flying towards Pallikaranai Marshland direction. In Medavakkam lake only once during mid of March we have sited some of these ducks but not on other days. that does not mean these birds are not present in Medvakkam wetland area, we might be missing the time for observing these birds.

The Indian spot-billed duck (Anas poecilorhyncha) is a large dabbling duck that is a non-migratory breeding duck throughout freshwater wetlands in the Indian subcontinent. The name is derived from the red spot at the base of the bill that is found in the mainland Indian population. When in water it can be recognized from a long distance by the white tertials that form a stripe on the side, and in-flight it is distinguished by the green speculum with a broad white band at the base. This species and the eastern spot-billed duck (A. zonorhyncha) were formerly considered conspecific, together called the spot-billed duck (A. poecilorhyncha) Source: Wikipedia.

A large grayish-brown duck with a diagnostic yellow-tipped black bill and a red spot at the base of the bill (missing in certain subspecies). In-flight, note the green panel in the wing that is bordered in white. Often seen in small groups dabbling or tipping up in shallow water or walking on marshy land at the edge of freshwater lakes or in cultivated fields. Usually not seen associating with other species. Similar to Eastern Spot-billed Duck, but note green wing panel, lack of a distinct dark "moustache", and overall warmer tan coloration (Source Ebirds).

    The Black-winged Stilt is very common in Perumbakkam marshland. we have not observed them at Medavakkam lake or near Annakkili Amma Research Institute. which makes us think that this bird is not visiting Medavakkam Marshland. The Perumbakkam marshland is a bigger area with a shallow water body which is the supporting habitat for the Black-winged Stilt. hence they reside more near Perumbakkam Marshland, the habitat is similar to Pallikaranai also, but are yet to visit Pallikaranai Marshland (The Major Marshland/wetland of Chennai)

The black-winged stilt (Himantopus himantopus) is a widely distributed very long-legged wader in the avocet and stilt family (Recurvirostridae). The scientific name H. himantopus was formerly applied to a single, almost cosmopolitan species. It is now normally applied to the form that is widespread in Eurosiberia and Africa and which was formerly regarded as the nominate subspecies of Himantopus himantopus sensu lato. The scientific name Himantopus comes from the Greek meaning "strap foot" or "thong foot". Most sources today accept 2–4 species. It is sometimes called pied stilt, but that name is now reserved for the Australian species, Himantopus leucocephalus (Wikipedia).

    Fairly common to locally common in warmer regions. Favors wetlands with open shallow water, often brackish; breeds on bare ground near water, often in noisy colonies. Striking and essentially unmistakable, with elegant shape, boldly pied plumage, long hot-pink legs, and long, very fine bill. Feeds by wading in the water, picking with its bill from the water surface. In-flight, long pink legs stick out far beyond the tail (ebird).

நெடுங்கால் உள்ளான் (Black-winged Stilt - Himantopus himantopus) என்பது நீண்ட கால்களைக் கொண்ட கரைப்பறவைகளுள் ஒன்றாகும். இது நீர் நிலைகளுக்கு அருகில் வாழக்கூடிய பறவை ஆகும்.

Grey Heron (Ardea cinerea)

             These birds have been spotted in Medavakkam Lake and also in Perumbakkam Marshland. the Grey heron was occasionally spotted at Medavakkam Lake but in the Perumbakkam Marshland area, it was found with high frequency.

               Generally quite common and conspicuous in wetland habitats from marshes and tidal flats to small ponds, ditches, and wet fields; nests colonially in tall trees. Mainly seen as singles or in small groups, standing quietly in or at the edge of the water, less often hunting in fields. Plumage mostly gray overall, with a paler neck; the adult has a white crown, black eyebrows, and black shoulder patch. Like other herons and egrets, flies with necks pulled in to form a bulge.

             The grey heron is a long-legged predatory wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn (Wikipedia).
