Galahs at greatest risk of hitting Canberra aircraft: ATSB

Galahs were the species most likely to crash into aircraft taking off or landing at Canberra Airport, according to the national air safety investigation bureau's latest statistics.

The pink and grey cockatoos familiar to Canberra's suburban residents are also common at the city's airport, crashing into planes more than 100 times in the past decade.

The parrots were responsible for 12 per cent of all bird strikes in the ACT from 2014 to 2015 and just under a third of all reported strikes between 2006 and 2015, the Australian Transport Safety Bureau report said.

Magpies, pipits, ducks, plovers, swallows, bats and a hawk were among the other birds hit in the territory during the most recent two-year reporting period.

Of the 117 bird strikes related to Canberra Airport, 112 happened within the confines of the aerodrome, four were between five to 15 kilometres from the runways and one was at an unknown distance.

The number of strikes at Canberra's airport was the third-lowest of any major capital city in 2014 and 2015, with only Hobart and Perth recording fewer hits.

But when factoring in the rate of bird strikes per 10,000 flight movements, Canberra had the second highest figure of any capital after Darwin, rising year on year from 3.47 in 2012 to 10.13 in 2015.

Only one of those strikes, however, was damaging to an aircraft in 2015. No damaging strikes were reported in 2014.

No ground based animals were hit during the two years at Canberra Airport.

Summer was the most common season for bird-plane strikes, while most of the birds hit aircraft during the morning peak from 5am to 9am.

Though the galah was the most commonly struck winged creature in the ACT, it ranked fifth nationally behind bats, swallows, kites and plovers.

An ATSB information sheet on managing the risk of galah strikes at Australian airports found abundant food or water sources, perching sites and foraging sites near aerodromes were the main attractions for the species of cockatoo.

The sheet suggested that airports consider culling, portable distress callers, or trained animals "such as birds of prey and dogs" to scare or move birds from airports.

"Not all the suggested strategies have been trialled at Australian airports and it may be necessary for each airport to independently trial any particular method before incorporating it into their bird management plan," the report said.

Other strategies suggested included letting grass grow tall, limit seed production in grasslands and weeds, as well as removing non-essential signs and posts to prevent perching areas.

Canberra Airport's master plan noted bird management policies included landscaping with plants unlikely to attract animals, minimising water ponding, preventing weeds and using wires, nets and spikes on exposed surfaces to stop birds from roosting.
