Eurasian Coot
Fulica atra
ABR description
The following is extracted from the Annual Bird Report for the twelve months to June 2017.
Very common, breeding resident
Another regular inhabitant of Canberra water bodies, but sometimes seen also in very large numbers on LBath and LGeo.
General: 14% increase in records to 2725, but numbers up only 2% to 65638. Spring records were down 35% from 2016. Ibis and some other waterbirds exhibited similar seasonal patterns, perhaps related to high rainfalls in winter and early spring (see Lenz, 2016). As can be seen from the graph, Coot almost disappeared entirely in spring and early summer. Records predominantly from the ACT with many records from JWNR, Lyneham Wetlands and Scrivener Dam. Otherwise, most records in Goulburn area. Max 1293/12 Feb Yerrabi Pond (GrB1) (up 25%), mean 24.7 (down 13% on last year), median 6 (down 25%). 121 breeding records, up 57% from 20 grid cells (up 2) predominantly dy. Breeding reporting rate 0.9%, up on 2016. Earliest record on/27 Aug, Fadden (CaR3), latest dy/26 Apr, North Watson, (CaR3).
GBS: No change in number of sites, but drop in records from last year of 32% and numbers 50%. Spring records down to 13.3% compared with long term averages of around 25%. Max, average and means down on last year and long-term averages. 18 breeding records from 2 sites, Jerrabomberra (HaL2) and Crace (LeF1), between 9 Oct and 5 March, all dy.
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 Eurasian Coot for 2017.
The red circles are the grid cells where Eurasian Coot 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 N16.
The size of the circle represents the reporting rate. The maximum reporting rate for Eurasian Coot was 100.0% (eg grid number N16) and the minimum was 0.5% (eg grid number M13). 
Distribution - all years
This map shows the observed distribution of the Eurasian Coot for all years.
The red circles are the grid cells where Eurasian Coot 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 A12.
The size of the circle represents the reporting rate. The maximum reporting rate for Eurasian Coot was 66.7% (eg grid number R30) and the minimum was 0.1% (eg grid number I15).
