Area commands were the major operational and administrative formations of the Royal Australian Air Force (RAAF) between 1940 and 1954. Four commands were raised in 1940, early in World War II, to oversee operations, training and maintenance within their geographical boundaries. In 1941–42 the structure was revised to make a total of five commands, along with four functional groups that assumed the training and maintenance roles. The area commands focused on operations until the end of hostilities. A new area command covering RAAF units in New Guinea existed from 1944 to 1947. By the early 1950s, the area command structure was no longer considered appropriate, and in 1953 it was transformed into Home Command (controlling operations), Training Command, and Maintenance Command. The area commands ceded their authority to these functional commands in 1954, and were disbanded by the end of 1956. ( This article is part of a featured topic: RAAF area commands .)
| | The white-booted racket-tail (Ocreatus underwoodii) is a species in the hummingbird family, Trochilidae. It is found in Colombia, Ecuador and Venezuela, where it inhabits humid forests and forest edges, most commonly at elevations of 1,600 to 2,200 metres (5,200 to 7,200 ft). The species shows pronounced sexual dimorphism: males have elongated outer tail feathers with bare shafts ending in distinctive oval flags, while both sexes have white leg puffs. It feeds primarily on nectar, but also catches small insects in flight. The female lays two eggs in a tiny cup nest constructed from plant fibres and lichen. This male white-booted racket-tail of the subspecies O. u. melanantherus was photographed in Refugio Paz de las Aves, a nature reserve in Ecuador, showing its green plumage and racket-shaped tail feathers while in flight.
