Overview
The Australian hobby (Falco longipennis), also known as the little falcon, is one of six Australian members of the family Falconidae. This predominantly diurnal bird of prey derives its name ‘longipennis’ from its long primary wing feathers. It occurs throughout Australia and other neighbouring countries with migrating individuals found on the islands of Indonesia and New Guinea.
Taxonomy
The Australian hobby is a member of the family Falconidae and the order Falconiformes. Five major clades have been established in the genus Falco. These include kestrels, merlins, hobbies, hierofalcons and peregrines. Hobbies are somewhat removed from these groups but are still a component of a more inclusive clade.
Three subspecies of Australian hobby are usually recognised. These are:
Falco longipennis longipennis, (Swainson, 1838)
Falco longipennis hanieli (Hellmayr, 1914) being slightly smaller and paler below than F. l. longipennis
Falco longipennis murchisonianus (Mathews, 1912) is paler blue-grey above with a dull blackish head, and paler reddish-brown below with less distinct markings.
Of the hobbies in existence including the African hobby (Falco cuvierii) and the Oriental hobby (Falco severus), the Australian hobby is closely related to the northern hobby (Falco subbuteo) which inhabits Eurasia and migrates to Africa during winter.
