Recurvirostra novaehollandiae

ABR description

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

Non-breeding vagrant

Mostly found on LBath and LGeo with sporadic sightings since 1988 in the ACT.

General: Big increase from a single sighting in 2016 in records (21), grid cells (6), numbers (339), abundance (0.0240) and reporting rates (0.1%), but all these measures, except records, are below the 30YA. Records are second highest since 1984.  Winter records were very low compared with long term averages, 5% compared with 24% 10YA and 34% 30YA. Spring and autumn records are higher than long-term levels. Records mainly from LBath (11) and LGeo (7) as well as Hoskinstown and JWNR. Max 106/20 Feb, LBath East Basin, (LeM1), mean 16.1, median 4. One breeding record, on/30 Oct, LBath East Basin, (LeM1), first since co/2008.

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 Red-necked Avocet for 2017.

The red circles are the grid cells where Red-necked Avocet 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 Red-necked Avocet was 52.9% (eg grid number Y8) and the minimum was 0.1% (eg grid number L14).

Distribution - all years

This map shows the observed distribution of the Red-necked Avocet for all years.

The red circles are the grid cells where Red-necked Avocet 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 Red-necked Avocet was 36.4% (eg grid number T8) and the minimum was 0.0% (eg grid number L11).
