Distribution map
Distribution - 2017
This map shows the observed distribution of the Sulphur-crested Cockatoo for 2017.
The red circles are the grid cells where Sulphur-crested Cockatoo 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 A9.
The size of the circle represents the reporting rate. The maximum reporting rate for Sulphur-crested Cockatoo was 100.0% (eg grid number A9) and the minimum was 4.3% (eg grid number R12). 
Distribution - all years
This map shows the observed distribution of the Sulphur-crested Cockatoo for all years.
