Distribution map
Distribution - 2017
This map shows the observed distribution of the Common Myna for 2017.
The red circles are the grid cells where Common Myna 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 M30.
The size of the circle represents the reporting rate. The maximum reporting rate for Common Myna was 100.0% (eg grid number M30) and the minimum was 0.6% (eg grid number I13). 
Distribution - all years
This map shows the observed distribution of the Common Myna for all years.
The red circles are the grid cells where Common Myna 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 Common Myna was 100.0% (eg grid number Z12) and the minimum was 0.2% (eg grid number F18).
