Straw-necked Ibis

Threskiornis spinicollis

ABR description

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

Common, non-breeding visitor

Often seen on well-watered grasslands, including playing fields and golf courses.

General: Compared with 2016, 2% more records, but overall numbers down 61% from 9159 to 3545. As with other Ibis species, spring presence was lower than expected: only 7 records out of 450, with the spring reporting rate, 0.2%, the lowest ever recorded. Overall reporting rate was down from 3.8% to 3.2%, dragged down by the low spring rate, but the same as the 20 & 30YA. Max 100/13 Aug, Collector Creek floodplain (LaK1), mean 8, median 2, all substantially lower than in 2016. Only 11 other records were for 50 or more birds including 90/15 Feb Wollogorang Lagoon (LeM1), 70/28 Jan Rose Lagoon (AnF1). A third of records from JWNR & FSP, but also from many widespread sites including suburban playing fields and peri-urban wetlands. No breeding reported.

GBS: 16 sites produced 52 records, down 21% on 2016 from 20 sites. Numbers observed, 500, down 46% on last year; reporting rate (2%) down 19% and abundance (0.19) down 39%, on last year but are substantially above the previous 10YA. Summer reporting rate (0.1%), much lower than long term averages. Autumn and winter had 88% of the records compared with the previous 10YA of 63%. Max, 90/31 Jul (VeP1) up by 80%, mean 9.6 and median 5, both down on last year. Sites were widely dispersed across Canberra suburbs, but also in rural areas. Max 13 from 2 sites in Giralang (KaD1 McD4), 10 from Curtin (AjR1) and 6 from Murrumbateman (BlJ1). No breeding recorded.

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 Straw-necked Ibis for 2017.

The red circles are the grid cells where Straw-necked Ibis 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 Straw-necked Ibis was 42.1% (eg grid number U3) and the minimum was 0.3% (eg grid number L12).

Distribution - all years

This map shows the observed distribution of the Straw-necked Ibis for all years.

The red circles are the grid cells where Straw-necked Ibis 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 S27.

The size of the circle represents the reporting rate. The maximum reporting rate for Straw-necked Ibis was 100.0% (eg grid number S27) and the minimum was 0.1% (eg grid number I14).
