considerably larger than the other two species. One or two eggs 
are laid on the bare ground. The black mask gives the sitting

it makes no attempt to resist being pushed from the egg, and 
when the egg is taken, and the fish has been vomited, it quietly 
walks away. No skin was obtained.

bushes in Keeling. The birds commonly perch on trees, and are
