Observations on Swamphens Breeding near Manjimup, W.A.

Observations of a breeding pair of Swamphens, Porhpyrio porphyrio, breeding near Manjimup, 480 km south of Perth, during 1976/77 are presented. After hatching the male constructs a nursery nest (Ridpath 1971) in a tussock of grass or amongst some reeds in a situation more easily accessible to the chicks where they can be brooded at night or at times during the day. Two or three of these nursery nests may be built at different sites within the territory, perhaps, to lesson the risk of predation.
