Distribution map
Distribution - 2017
This map shows the observed distribution of the Yellow Thornbill for 2017.
The red circles are the grid cells where Yellow Thornbill 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 J3.
The size of the circle represents the reporting rate. The maximum reporting rate for Yellow Thornbill was 100.0% (eg grid number J3) and the minimum was 0.1% (eg grid number J14). 
Distribution - all years
This map shows the observed distribution of the Yellow Thornbill for all years.
The red circles are the grid cells where Yellow Thornbill 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 W3.
The size of the circle represents the reporting rate. The maximum reporting rate for Yellow Thornbill was 100.0% (eg grid number W3) and the minimum was 0.1% (eg grid number L25).
