Southern Boobook

Ninox boobook

ABR description

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

Common, breeding resident

The most numerous of our local owls, heard more often than seen in the suburbs. In serious decline nationally, according to BirdLife Australia (2015).

General: 45 records, all single birds except for 2/15 Mar O’Connor (MiP1). From 24 mainly urban grid cells. The reporting rate of 0.3%, while the same as last year, is well below the 30YA of 1.2%. Recorded in 26 weeks: winter 11%; spring 38%; summer 27% and autumn 24%.

GBS: 78 records, at a reporting rate of 3.0% compared with a long-term average of 3.4%. The abundance value of A=0.0327 is holding up reasonably well against the long-term average of A=0.0374. Mainly single birds. Max 3/1 Jan Burra GrM20 (AnI1). Recorded over 34 weeks, with 6% of records in winter, 30% spring,42% summer and 22% autumn. From 13 grid cells; relatively common only in Cook and Ainslie. One possible breeding record: ih/28 Aug Watson GrL12 (WaK1), where boobooks have bred before.

Abundance

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.

Distribution map

Distribution - 2017

This map shows the observed distribution of the Southern Boobook for 2017.

The red circles are the grid cells where Southern Boobook 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 U16.

The size of the circle represents the reporting rate. The maximum reporting rate for Southern Boobook was 100.0% (eg grid number U16) and the minimum was 0.1% (eg grid number L14).

Distribution - all years

This map shows the observed distribution of the Southern Boobook for all years.

The red circles are the grid cells where Southern Boobook 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 V27.

The size of the circle represents the reporting rate. The maximum reporting rate for Southern Boobook was 100.0% (eg grid number V27) and the minimum was 0.1% (eg grid number I11).
