ABR description
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Uncommon, non-breeding visitor
A nomadic inland species, whose presence is dependent on water levels at lakes such as LGeo/LBath.
General: The decline in numbers appears to be continuing from the large number reported in 2013-14. All indices show a decline; number of grid cells 15 cf 25 last year, abundance from 1.21 to 0.46 and reporting rate from 5.5% to 2.6%. Max similar to last year 670/4 Jun LGeo GrT09 (LeM1). Reported throughout the year with few in spring to a maximum during autumn (43%). Most observations from Lakes Rd LGeo GrR12, FSP, JWNR, MFNR Big Dam and WBPD. Breeding (dy) was reported on 4 occasions between 5 Dec and 28 Jan from MFNR Big Dam GrL10. Possibly the same breeding pair that bred in the same location last year.

Distribution map
Distribution - 2017
This map shows the observed distribution of the Pink-eared Duck for 2017.
The red circles are the grid cells where Pink-eared Duck 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 Pink-eared Duck was 39.1% (eg grid number T9) and the minimum was 0.2% (eg grid number K14). 
Distribution - all years
This map shows the observed distribution of the Pink-eared Duck for all years.
