The Hamerkop is unmistakable, with his oddly crested head and long, stout bill. He resides in Africa and Madagascar, making wetlands his home - estuaries, ponds and even cultivated wetlands such as rice paddies or canals. Hamerkop are relatively sedentary and usually live in pairs. Their nest is a huge, extravagant domed affair - sometimes more than 1.5 m across. It is built in the fork of a tree, often over water and decorated with brightly coloured objects. A tunnel leads to a large nesting chamber in which the female lays up to seven eggs.
