Acanthiza reguloides
ABR description
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Common, breeding resident
Forages in the middle levels of foliage in drier grassy woodlands.
General: Number of birds (5562) down by 18% on last year but numbers much higher than 10 (3061) and 30YAs (1759). Reporting rate 7.2% is 26% down on last year, and well under the 10 and 30YA and is still declining since 1999 towards its lowest value ever. Mean 5.7, median 4, max 42/9 Apr Michelago Grl24 (HeS1). 48 breeding records from 20 grids. First breeding nb/16 Jul The Pinnacle NR (AlB1) and last dy/17 Apr The Pinnacle NR (AlB1).
GBS: A massive reduction in records from 86 last year to only 19 this year from only 2 rural and 1 suburban site (5%), and only 19 weeks. There were only 2 sightings in Canberra suburbs. The plummeting abundance value, and reporting rate make for a very pessimistic outlook for this species in Canberra gardens. Abundance (A=0.0238) is 78% lower than last year and down 88% on the 10YA. Average 3.2, median 2, with max 6/2wk Feb Giralang (McD4). No breeding records.

Distribution map
Distribution - 2017
This map shows the observed distribution of the Buff-rumped Thornbill for 2017.
The red circles are the grid cells where Buff-rumped 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 Buff-rumped Thornbill was 100.0% (eg grid number A9) and the minimum was 0.2% (eg grid number J14). 
Distribution - all years
This map shows the observed distribution of the Buff-rumped Thornbill for all years.
The red circles are the grid cells where Buff-rumped 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 P30.
The size of the circle represents the reporting rate. The maximum reporting rate for Buff-rumped Thornbill was 100.0% (eg grid number I1) and the minimum was 0.3% (eg grid number I11).
