Spotted Harrier

Circus assimilis

The following is extracted from the Annual Bird Report for the twelve months to June 2017.

Uncommon, non-breeding visitor

Declared vulnerable in NSW. This handsome harrier’s stronghold is the arid and semi-arid zones so its presence in the ACT is irregular.

General: Only 5 records this year, all single birds, from two grid cells – GrR16 (Carwoola) and GrL14 (JWNR). 1 in spring and 4 in summer. Over the last 30 years’ record, numbers for this species have varied from one to 91 (in 2013).

GBS: No records this year. There have been harrier GBS records in only 4 of the previous 30 years.

Abundance is the average number of birds of that species per survey. Where the species was observed (presence recorded) but the number of birds seen was not recorded, this is treated as a count of zero.

This chart shows the abundance of Spotted Harrier between 1982 and 2017.

This chart shows the monthly abundance of Spotted Harrier. The blue lines show the abundance for the twelve months to June 2017 and the bars show the average abundance for the period 1982 to 2017.

This chart shows the seasonal abundance of Spotted Harrier. The blue lines show the seasonal abundance for the twelve months to June 2017 and the bars show the average seasonal abundance for the period 1982 to 2017.

This map shows the observed distribution of the Spotted Harrier for 2017.

The red circles are the grid cells where Spotted Harrier 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 Spotted Harrier was 20.0% (eg grid number R16) and the minimum was 0.1% (eg grid number L14).

This map shows the observed distribution of the Spotted Harrier for all years.

The red circles are the grid cells where Spotted Harrier 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.

The size of the circle represents the reporting rate. The maximum reporting rate for Spotted Harrier was 66.7% (eg grid number H29) and the minimum was 0.0% (eg grid number K13).
