This map shows the observed distribution of the Blue-billed Duck for 2017.
The red circles are the grid cells where Blue-billed Duck 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 A11.
The size of the circle represents the reporting rate. The maximum reporting rate for Blue-billed Duck was 18.2% (eg grid number K3) and the minimum was 1.4% (eg grid number L14).
This map shows the observed distribution of the Blue-billed Duck for all years.
The red circles are the grid cells where Blue-billed Duck 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.
