s. Very little was known of the breeding habits of this bird so a study was undertaken in 1991. Nine birds were in the vicinity of the study site, four pairs and a single bird. There was much vocalisation mostly in the form of duetting and choruses, with all the birds joining in synchrony. Calling took place in the mornings and to a lesser extent in the afternoons indicating the presence of birds close to the nest. The study nest was a cone-shaped mound in a fallow cultivated field close to scrub and forest remnants. It was built over two rotting logs and was constructed of sand and clay. Eggs are laid by the female in the mound and covered with soil (this was not observed). During the month-long observation period, a bird (or sometimes two) would approach the mound on most days and rake the surface with its claws. The bird faced downhill and scratched the surface with alternate feet, working in one instance for 116 minutes. Another bird could sometimes be heard in the nearby undergrowth. 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'').

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

Status

''M. bernsteinii'' faces a number of threats and its total population is thought to be declining. 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. The total area of occupancy of this bird is only about and the
