Australian Hobby

Smaller than other falcons, the Australian hobby is relatively slender and long winged. Its plumage varies in colour depending on sex, age and environment with a darker form in humid areas and a lighter form in drier environments. Generally the hobby displays a black cap and mask with a whitish forehead and half-collar. Underparts can be blue-grey or rufous and streaked darker. The cere in adults is a pale yellowish grey, the eye ring is pale blue, the eyes are brown and the feet are dull yellow. Females are larger in size between 34 and 35.5 cm and males are generally between 30 and 32 cm in length with a wing span between 66 and 87 cm. The Australian hobby is easily confused with the peregrine falcon (Falco peregrinus) however the hobby is more slender, with longer and thinner wings, and is a less powerful flyer.

Hobbies occur throughout mainland Australia including offshore islands e.g. Lord Howe Island, however their range is restricted in Tasmania. Migrating individuals have also been recorded on the islands of Indonesia and New Guinea. Hobbies frequent most open habitats including open woodland, water courses and vegetated urban areas but are rarely recorded around cliffs or escarpments.

The Australian hobby has been recorded preying on avian species including the European starling (Sturnus vulgaris), house sparrow (Passer domesticus), crimson rosella (Platycercus elegans) and silvereye (Zosterops lateralis). Research suggests they tend to avoid large, dangerous, or agile species that forage close to cover, such as the common myna (Acridotheres tristis). Insectivorous bats and insects including beetles, cicadas, crickets and grasshoppers also form part of the hobby's diet.
