Home Ranges of Eastern Ground Parrots

David McFarland's radio-tracking work on Ground Parrots in Cooloola National Park, South-Eastern Queensland yielded some information about their home range.

Home ranges are very likely to overlap to some extent. Each of the figures below shows the same place. 

At the time of  radio-tracking in each season, between three and five parrots, including the tagged bird were flushed in area A (Figure 2, a). (McFarland, 1991)

There was little overlap in foraging ranges among tracked individuals, and no two tagged birds foraged in the same area on the same day (Figure 2, a-c) (McFarland, 1991)
