10 ton 35-foot whale was successfully towed back to sea. This was the first successful rescue of a beached whale in Asia. Waterbirds This site has recorded the second largest congregation of migratory waterbirds in India, with a peak population in excess of 100,000, representing 103 species. Bombay Natural History Society researchers have captured, studied, ringed and released over 200,000 birds during the course of several ornithological studies here in the past several years. In October these waterbirds arrive from Rann of Kutch, Eastern Siberia, Northern Russia, Central Asia and parts of Europe for their feeding season and start returning to those breeding places in January. These waterbirds include threatened species such as spot-billed pelican, Nordmann's greenshank, spoonbill sandpiper and black-necked stork. Near threatened species include black-headed ibis, Asian dowitcher, lesser flamingo, spoonbill, darter and painted stork. Landbirds Over of the best tropical dry evergreen forest in India are in the sanctuary. They harbour a large variety of resident and migratory landbirds. The most common of the 35 resident species are white-browed bulbul, brahminy kite, small green-billed malkoha, crow pheasant, rose-ringed parakeet, grey partridge, blue-tailed bee-eater and common iora. Spotted and collared doves are common in the mangroves. Flora This site is a mix of salt swamps, mangroves, backwaters, mudflats, grasslands and tropical dry evergreen forests. 364 of flowering plant species have been identified in the sanctuary of which 50% are herbs and the others are climbers, shrubs and trees. About 198 of these have medicinal properties. Manilkara hexandra, locally called Palai is the dominant dry evergreen species and an important food source for fruit eating birds. Middle canopy is dominated by the invasive Prosopis juliflora and the most abundant undergrowth is Memecylon umbellatum. Threats Major threats to the natural biodiversity and ecological balance of the sanctuary are: loss of habitat for waterbirds, soil and water salinisation by adjacent salt pans, spread of the invasive Prosopis juliflora, cattle grazing and scarcity of fresh water. Sanctuary staff conduct programs to alleviate all these issues. Visitor information The sanctuary is open all year from 6 am to 5 pm. The best weather at the sanctuary is during November and December when the area is cooled by the Northeast monsoon and the grasslands are the most luxuriant. The best time for bird watching is from October to January and the best time for animal viewing is from March to August. The sanctuary entrance
