Distribution map
Distribution - 2017
This map shows the observed distribution of the Grey Butcherbird for 2017.
The red circles are the grid cells where Grey Butcherbird have been reported.
The transparency of the red circles indicate how many surveys sheets were submitted for that grid cell; the darker the red the more reliable the data. Of the 315 grid cells with reports, 83 had only one sheet; an example is grid number E21.
The size of the circle represents the reporting rate. The maximum reporting rate for Grey Butcherbird was 100.0% (eg grid number E21) and the minimum was 0.4% (eg grid number S13).
