ABR description
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Common, breeding resident/summer migrant
A widespread, easily identified, largely summer migrant. Some of the population over-winters here.
General: 3,882 birds recorded (last year 4,180) though far more than the 10YA (1,728) and the 30YA (920). Recorded in every week, with a marked spring and summer peak (both 39%), compared with autumn (17%) and winter (6%). Reporting rate (13%) similar to last year (15%), but below the 10YA (19%) and the 30YA (20%). Recorded from 50% of grid cells surveyed, just above to last year’s 47%, the 10YA (45%) and the 30YA (43%). Max 20 (49 last year), mean 2.1, median 1. 53 breeding records (39 last year), from br/9 Oct Greenway GrJ17 (CnM1) to cf/29 Mar Isaacs Ridge NR-Mugga Lane GrL15 (HeS1).
GBS: 671 birds recorded (last year 760) though fewer than the 10YA (922) and the 30YA (1,085). 460 records (last year 479), fewer than the 10YA (625) and the 30YA (722). Recorded in all weeks with higher proportions in spring (36%) and summer (37%) than in autumn (22%) and winter (5%). Records from 78% of sites, a similar proportion to last year (85%), the 10YA (81%) and the 30YA (87%). Abundance (0.2613) identical to last year, close to the 10YA (0.2881), though lower than the 30YA (0.3988). Max 7 (12 last year), mean 1.5, median 1. 9 breeding records (8 last year) from just 3 sites: first di/5wk Oct Curtin GrK14 (AjR1) and last dy/3wk Holt GrI12 (DaC1).
Abundance

Distribution map
Distribution - 2017
This map shows the observed distribution of the Black-faced Cuckoo-shrike for 2017.
The red circles are the grid cells where Black-faced Cuckoo-shrike 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 Black-faced Cuckoo-shrike was 100.0% (eg grid number E3) and the minimum was 2.0% (eg grid number K15). 
Distribution - all years
This map shows the observed distribution of the Black-faced Cuckoo-shrike for all years.
The red circles are the grid cells where Black-faced Cuckoo-shrike 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 C10.
The size of the circle represents the reporting rate. The maximum reporting rate for Black-faced Cuckoo-shrike was 100.0% (eg grid number A7) and the minimum was 2.3% (eg grid number S13).
