Both Bibra Lake and North Lake are a constantly changing scene of bird life.
As well as providing one of the last remaining natural habitats for the endangered Carnaby’s Cockatoo, other bird species come and go according to the seasons and the water level. The lakes are seasonal wetlands, so they will usually dry out in summer. This fluctuation in water level allows for a greater variety of bird life to use the lakes. The creatures that live in the lake water are all adapted to survive the dry period.
The waders, for example, move in as the water is receding, while diving birds such as the Blue billed duck move out at this time.
The wetlands and bushland host migratory birds from near and far. The beautiful Rainbow Bee Eater breeds in the North Lake reserve by making a long underground tunnel in the sand. These birds then spend the winter in the warmth of northern Australia or even Papua New Guinea and eastern Indonesia.
The lakes also host several species migrating from the northern hemisphere including the Common Green Shank.
