Sarus Crane (Antigone antigone)










The sarus crane (Antigone antigone) is a large non-migratory crane found in parts of the Indian Subcontinent, Southeast Asia and Australia. The tallest of the flying birds, standing at a height of up to 1.8 metres, they are conspicuous and iconic species of open wetlands. The sarus crane is easily distinguished from other cranes in the region by the overall grey colour and the contrasting red head and upper neck.

They forage on marshes and shallow wetlands for roots, tubers, insects, crustaceans and small vertebrates. Like other cranes, they form long-lasting pair-bonds and maintain territories within which they perform territorial and courtship displays that include loud trumpeting, leaps and dance-like movements. In India they are revered and considered symbols of marital fidelity, believed to mate for life and pine the loss of their mates even to the point of starving to death.

The main breeding season is during the monsoons, when the pair builds an enormous nest "island", a circular platform of reeds and grasses nearly two metres in diameter and high enough to stay above the shallow water surrounding it.

Grey-headed Swamphen aka Purple Moorhen

Female Grey-headed Swamphen
Grey-headed swamphen (Porphyrio poliocephalus) is a species of swamphen or moorhen occurring from the Middle East and the Indian subcontinent to southern China and northern Thailand. It used to be considered a subspecies of the purple swamphen, but was elevated to full species status in 2015; today the purple swamphen is considered a superspecies and each of its six races are designated full species.

The male has an elaborate courtship display which is more like children playing catch-me-if-you-can game. Their calls are also amusing as they do not keep to any standard call sometimes cackling like hens, sometimes hooting, sometimes hissing and shrieking. The male is seen to entice a female by holding a piece of reed in his beaks and offering it to females.The male is a glistening purple color and the female is a little duller than the male with greyish-purple color; both have a red patch on a bald head.

They forage on insects, mollusks, water beetles, and water-plant shoots. The nesting season is from June to September. The nest is a large pad of reed leaves on a floating mass or hidden inside the reed beds.  Three to six eggs (pale yellowish color and blotched or spotted with reddish brown patches) are laid at a time.
