Distribution map
Distribution - 2017
This map shows the observed distribution of the Yellow-tailed Black-Cockatoo for 2017.
The red circles are the grid cells where Yellow-tailed Black-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 M6.
The size of the circle represents the reporting rate. The maximum reporting rate for Yellow-tailed Black-Cockatoo was 100.0% (eg grid number M6) and the minimum was 0.6% (eg grid number I13). 
Distribution - all years
