Acanthiza pusilla

ABR description

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

Very common, breeding resident

Found everywhere in the region except open grasslands.

General: When observer effort is considered, indices such as the abundance and reporting rates show little overall long term change since 1991. However, the reporting rate (11.3%) is down on last year and is below the 30YA (15.7%). Mean 2.4, median 2, max 18/18 Mar Blundells Ck Rd (KyP1). 11 widely scattered breeding records in 9 grids commencing with dy/9 Oct Michelago Grl24 (AlB1) and concluding with dy/26 Jan NNP Mt Ginini (HoS1).

GBS: 539 records from 33 sites (56%), from all weeks. Numbers of birds (989) well down on last year, but up 9% on 30YA. Abundance (A=0.3851) is 17% down on last year but still 15 % above the 30YA. Average 1.8, median 2. Only 2 breeding records (long-term average 2.5) at 1 site: ny/3wk Oct and dy/1wk Nov at Curtin (AjR1).

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 Brown Thornbill for 2017.

The red circles are the grid cells where Brown Thornbill 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 A9.

The size of the circle represents the reporting rate. The maximum reporting rate for Brown Thornbill was 100.0% (eg grid number A9) and the minimum was 0.8% (eg grid number L12).

Distribution - all years

This map shows the observed distribution of the Brown Thornbill for all years.

The red circles are the grid cells where Brown Thornbill 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 A5.

The size of the circle represents the reporting rate. The maximum reporting rate for Brown Thornbill was 100.0% (eg grid number A15) and the minimum was 0.5% (eg grid number S13).
