Reporting rate is at a record low, (3.3%) less than last year (4.8%), the 10YA (5.0%) and the 30YA (5.3%). Recorded from 20% of grid cells surveyed (21% last year), similar to the 10YA (20%) and the 30YA (17%). Max 15, mean 1.5, median 1. 14 breeding records (31 last year, an unusually high number), more than the 10YA (6.5) and the 30YA (4.4), all from Canberra suburbs or nature reserves, from on/29 Nov Ginninderra Creek-Latham GrI12 (KiB1) to dy/19 Feb LGin Pen (AlB1).

Records from 39% of sites (40% last year), similar to the 10YA (41%) and the 30YA (42%). Abundance lower than last year (A=0.0495), the 10YA (0.0646) and 30YA (0.0627). Max 4, mean 1.1, median 1. No breeding records (2 last year).

Distribution map
Distribution - 2017
This map shows the observed distribution of the Olive-backed Oriole for 2017.
The red circles are the grid cells where Olive-backed Oriole 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 J3.
The size of the circle represents the reporting rate. The maximum reporting rate for Olive-backed Oriole was 100.0% (eg grid number J3) and the minimum was 0.2% (eg grid number J14). 
Distribution - all years
This map shows the observed distribution of the Olive-backed Oriole for all years.
The red circles are the grid cells where Olive-backed Oriole 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 X28.
The size of the circle represents the reporting rate. The maximum reporting rate for Olive-backed Oriole was 100.0% (eg grid number X28) and the minimum was 0.1% (eg grid number K11).
