Distribution map

Distribution - 2017

This map shows the observed distribution of the Grey Shrike-thrush for 2017.

The red circles are the grid cells where Grey Shrike-thrush 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 Grey Shrike-thrush was 100.0% (eg grid number A9) and the minimum was 0.3% (eg grid number L12).

Distribution - all years

This map shows the observed distribution of the Grey Shrike-thrush for all years.
