Distribution map
Distribution - 2017
This map shows the observed distribution of the Horsfield’s Bronze-Cuckoo for 2017.
The red circles are the grid cells where Horsfield’s Bronze-Cuckoo 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 W12.
The size of the circle represents the reporting rate. The maximum reporting rate for Horsfield’s Bronze-Cuckoo was 100.0% (eg grid number W12) and the minimum was 0.1% (eg grid number J14). 
Distribution - all years
This map shows the observed distribution of the Horsfield’s Bronze-Cuckoo for all years.
The red circles are the grid cells where Horsfield’s Bronze-Cuckoo 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 X15.
The size of the circle represents the reporting rate. The maximum reporting rate for Horsfield’s Bronze-Cuckoo was 100.0% (eg grid number X15) and the minimum was 0.1% (eg grid number S13).
