Distribution map
Distribution - 2017
This map shows the observed distribution of the Double-barred Finch for 2017.
The red circles are the grid cells where Double-barred Finch 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 M9.
The size of the circle represents the reporting rate. The maximum reporting rate for Double-barred Finch was 100.0% (eg grid number M9) and the minimum was 0.3% (eg grid number L12). 
Distribution - all years
This map shows the observed distribution of the Double-barred Finch for all years.
The red circles are the grid cells where Double-barred Finch 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 A12.
The size of the circle represents the reporting rate. The maximum reporting rate for Double-barred Finch was 25.0% (eg grid number E2) and the minimum was 0.2% (eg grid number F18).
