Distribution map
Distribution - 2017
This map shows the observed distribution of the Gang-gang Cockatoo for 2017.
The red circles are the grid cells where Gang-gang 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 G23.
The size of the circle represents the reporting rate. The maximum reporting rate for Gang-gang Cockatoo was 100.0% (eg grid number G23) and the minimum was 0.4% (eg grid number J17). 
Distribution - all years
This map shows the observed distribution of the Gang-gang Cockatoo for all years.
The red circles are the grid cells where Gang-gang 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 703 grid cells with reports, 55 had only one sheet; an example is grid number B13.
The size of the circle represents the reporting rate. The maximum reporting rate for Gang-gang Cockatoo was 100.0% (eg grid number B13) and the minimum was 0.1% (eg grid number J17).
