Australian Hobby
Falco longipennis
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. Voice: Research undertaken comparing the vocalisations of Australian falcons, found that two structurally distinct calls were emitted when a male hobby was restrained. This included a wide band harmonic vocalisation and a trill-type vocalisation.
