are off-white. The bird is lanky and has a long slender S-shaped neck with a
narrow head and pointed bill. The bill, which is pinkish yellow in colour,

outstretched, as in case of other storks. An adult painted stork measures
95-100 m in height. It breeds in countries like India and Sri Lanka along
with southeast Asia.
The plumage of the painted stork is white above with black flight feathers.
The long bill is yellow in colour and is slightly curved near the tip. The
face of the bird is waxy yellow and unfeathered while the tail quills are
black. The young ones have the same pattern of colours but are a duller
version of the adults. The bird eats upon fish, frog and large insects.

breast and white underparts. It lays three eggs which are greenish grey to
