With a GPS tracker strapped on its back one of the ACT's rarest birds of prey has been shown to migrate from Canberra to the Northern Territory.
The study used tracked a little eagle, a threatened species in the ACT and a quarter of the size of a wedge-tailed eagle.
The little eagle's flight path stretched 3,300 kilometres and took it to Daly Waters in the Northern Territory. The distance was travelled in a three-week period.
The migration was documented as part of a combined ecological research study undertaken by the ACT government, University of Canberra, CSIRO and Ginninderry Joint Venture.
The male bird travelled 1800 kilometres in the first eight days, and during its journey reached speed of up to 55 kilometres per hour.
The images used by the research team to follow the journey illustrate where the male bird chose to roost.
Minister for the Environment Mick Gentleman said the little eagle which was tracked was part of a Belconnen pair that had successfully raised a chick in the spring and early summer period.
"The little eagle was suspected of migrating between breeding and wintering territories. This study provides the first proof of this and a clear indication of the vast distances involved," Mr Gentleman said.
The minister was fascinated to learn more about the habits of this bird of prey and said findings from the research would guide future management plans and inform development plans in the ACT.
"During the nesting season, the male is thought to have hunted mainly juvenile rabbits and middle sized birds such as magpies, rosellas and starlings over an area of 65 square kilometres, ranging from the junction of the Molonglo and Murrumbidgee rivers north-east to the CSIRO land along the Barton Highway and north to Wallaroo in NSW."
