A nestling and a missed opportunity

Following are extracts from the report "Western Ground Parrot nest search at Waychinicup September and October 2001". A nestling was located but due to the lack of knowledge about what a nestling would sound like, the opportunity for following up was lost. The surveys were from 6 to 13 September and 4-17 October. Communications were not as easy in those pre-Google days as now.

BOC is the Bird Observers' Club.










Note: Another predator known to be common near the swamp was the feral cat. The dry season could have allowed cats to encroach on the islands which in a wetter year would be protected by being ringed with water.

Roost sites, territory, and number of birds


From "Western Ground Parrot nest search at Waychinicup September and October 2001".

The map below (Fig. 4) shows the roosting sites of three pairs of Western Ground Parrots at the time of the surveys (September and October 2001). The roosting areas were 1.2 - 2 ha.in size and approximately 250 - 300 metres apart. Each roosting site was an 'island' slightly above the general level of the swamp and with a wider range of plants than the sedges of the swamp floor. The dense sedges of the swamp floor are about 0.75 metre above ground, and the dense vegetation of the roost sites stands to about 1.5 metres above the ground.
 
A fourth and similar island, near the lake, was not being used as a roost site.
