ABR description
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Uncommon, breeding resident
A common resident and breeding species, the most observed raptor in the region.
General: 590 records, including 9 WOO, making the kestrel the most recorded and the most numerous raptor in our region once again, though the Wedge-tailed Eagle is marginally more widespread. The reporting rate of 4.2% was the lowest since 2004 and down on the 30YA of 6.9. Numbers ranged from 1-9, average 1.4, median 1; max 9/29 Oct Callum Brae NR GrL15 (SmA1). Recorded in every week: winter 17%; spring 35%; summer 32%; and autumn 17%, the usual seasonal spread. Recorded from 120 widespread grid cells. As in most years, there were breeding records, 10 this time, from ih/20 Aug Wanniassa Hills NR GrK16 (CaR3) to dy/24 Jan MFNR GrL11 (ClJ3).
GBS: 50 records this year, an improvement on last year. The reporting rate was 1.9%, up on the 30YA of 1.5%. Kestrels were recorded in 34 weeks, and in all seasons, with the highest number of records again coming in autumn (50%). 10 urban and 2 rural sites were involved, though kestrels were not particularly common in any of them.

Distribution map
Distribution - 2017
This map shows the observed distribution of the Nankeen Kestrel for 2017.
The red circles are the grid cells where Nankeen Kestrel 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 E3.
The size of the circle represents the reporting rate. The maximum reporting rate for Nankeen Kestrel was 100.0% (eg grid number E3) and the minimum was 0.1% (eg grid number K13). 
Distribution - all years
This map shows the observed distribution of the Nankeen Kestrel for all years.
The red circles are the grid cells where Nankeen Kestrel 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 E27.
The size of the circle represents the reporting rate. The maximum reporting rate for Nankeen Kestrel was 100.0% (eg grid number E27) and the minimum was 0.3% (eg grid number K13).
