Sula megapode

The sexes are similar in appearance, being a uniform reddish-brown colour and having a short, pointed crest and long red or orange-red legs and feet.

Calling took place in the mornings and to a lesser extent in the afternoons indicating the presence of birds close to the nest.

The scratching bird was alert to danger, freezing at unexpected noises, and peering round and responding to the warning cries of the blue-backed parrot (Tanygnathus sumatranus) and the spangled drongo (Dicrurus bracteatus).

Monitor lizards (Varanus) sometimes tried to raid the nest, usually after an adult bird had been raking, but had little success while the researchers were watching.

Its natural forest habitat is threatened by logging and is being converted into agricultural land, the birds are hunted and their eggs collected for human consumption, and they and their young are preyed on by feral cats and dogs.
