The Hammerkop (Scopus umbretta), about the size of a small egret, is entirely brown, with a robust crest which gives its head a hammer-like appearance. This pronounced head crest makes it unmistakable. The bill is long, laterally compressed, blade-like and tipped with a sharp hook. Its legs are strong and endowed with narrowly webbed toes.
This bird is related to the storks but is different enough to be placed in a separate family (Family Scopidae) of which it is the only member species.Perhaps what the hammerkop is knowned for is massive nest built mostly on a tall V-shaped branched acacia tree.Hammerkops feed mostly on frogs,fish and tadpoles, and they also take small crustaceans, grasshoppers, and aquatic insects. They often rest during the day and become active at twilight, when they are most often encountered, often alone. They range throughout Kenya.
