Juvenile pale greyish-brown above, dirty white below, with dull bare parts. HabitatRivers, lakes, deltas, estuaries.Similar to P. onocrotalus, but does not need lowlands and more readily freeds in smaller colonies; less opportunistic, tending to stick to traditional breeding locations. Nests on islands or in dense aquatic vegetation, extensive reedbeds of phragmites. Typically winters on jheels and lagoons in India, on ice-free lakes in Europe. Sometimes fishes inshore along sheltered coasts. H4>Food and FeedingNormally solitary feeder or in small group of 2 or 3 birds, typically swimming along and suddenly pounging head into water to catch fish; in co-operative groups on occasions;recorded fishing in conjunction with cormorants at Greece.
