Spoonbills are a group of large, long-legged wading birds in the family Threskiornithidae, which also includes the Ibises.

All have large, flat, spatulate bills and feed by wading through shallow water, sweeping the partly opened bill from side to side. The moment any small aquatic creature touches the inside of the bill—an insect, crustacean, or tiny fish—it is snapped shut. Spoonbills generally prefer fresh water to salt but are found in both environments. They need to feed many hours each day.

Spoonbills are monogamous, but, so far as is known, only for one season at a time. Most species nest in trees or reed-beds, often with ibises or herons. The male gathers nesting material—mostly sticks and reeds, sometimes taken from an old nest—the female weaves it into a large, shallow bowl or platform which varies in its shape and structural integrity according to species.

The female lays a clutch of about 3 smooth, oval, white eggs and both parents incubate; chicks hatch one at a time rather than all together. The newly hatched young are blind and cannot care for themselves immediately; both parents feed them by partial regurgitation. Chicks' bills are short and straight, and only gain the characteristic spoonbill shape as they mature. Their feeding continues for a few weeks longer after the family leaves the nest. The primary cause of brood failure appears not to be predation but starvation.


Species and distribution

The six species of spoonbill in two genera are distributed over much of the world.

  • Eurasian Spoonbill (Platalea leucorodia): This is the most widespread species, which occurs in the northeast of Africa and much of Europe and Asia across to Japan. Adults and juveniles are largely white with black outer wing-tips and dark bills and legs. Breeds in reed-beds, usually without other species.
