Distribution map
Distribution - 2017
This map shows the observed distribution of the Yellow-rumped Thornbill for 2017.
The red circles are the grid cells where Yellow-rumped 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 A9.
The size of the circle represents the reporting rate. The maximum reporting rate for Yellow-rumped Thornbill was 100.0% (eg grid number A9) and the minimum was 0.4% (eg grid number K15). 
Distribution - all years
This map shows the observed distribution of the Yellow-rumped Thornbill for all years.
The red circles are the grid cells where Yellow-rumped 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 B13.
The size of the circle represents the reporting rate. The maximum reporting rate for Yellow-rumped Thornbill was 100.0% (eg grid number B13) and the minimum was 0.4% (eg grid number D16).
