Asian Openbill

Asian Openbill

This is a large wading bird called Asian Openbill, Anastomus Oscitans, in the stork family Ciconiidae.

Although it is relatively smaller compared to other storks, you’ll still be captivated by it’s broad wings once it flies.

This bird walks slowly, making it a good technique not to frighten its prey, feeding mostly on mollusks, frogs and enormous water insects, even apple snails – helping farmers in return as snails are also considered farm pests.

When feeding, the bird makes good use of its big open bill, yes this is where it got its name, scooping it along the shallows like a big spoon.


I shoot this bird early in the morning at one of the big parks of Bangkok. They are very common in the city as the parks are largely created with ponds and little lakes, making it a decent living space for these fowls for settling or reproducing.

As most birds do, inspite its size, the Asian Openbill also builds their nest in trees using sticks.
