VII. AUSTRALIAN BIRDS. 57 



forming bays, in which the birds will be found arranged in their 

 respective orders. Returning to the south-western portion of the 

 northern wing, or left-hand side, will be found the first order. 



Order ACOIPITRES. Every known species on the Aus- 

 tralian continent is here represented. In the first Bay is a group 

 of Wedge-tailed Eagles fAquila audaxj, and the White-bellied 

 Sea Eagle {Ilaliaetus leucogaster). These birds are almost equal 

 in size, and are the largest of all the Australian Birds of Prey. 

 The Whistling Eagle [JSaliastur sphenurus) is also in this case. 

 In the centre of this bay, in the wall case, is a collection of 

 Hawks, Harriers, Kestrels, &c., the most conspicuous of them 

 being the Grey-backed, or New-Holland Goshawk (Astur cinereus), 

 the Tasmanian Goshawk (^Astur novce-hollandice), the former of 

 which in the male has snow-white plumage, and in the female an 

 ashy-grey back ; but in the latter both sexes are white. Both 

 species are found in Australia, but the latter form appears to be con- 

 fined to Tasmania. The Black- shouldered Kite {Elamis axillaris), 

 the Nankeen Kestrel ( Tinnunculus cenchroides), the Collared Spar- 

 row Hawk {Accipiter cirrhocepTialus), the Black Falcon (Falco 

 subniger), and the Black-breasted Buzzard {Gypoictinia melano- 

 sternon), are all deserving of careful examination. On the right- 

 hand side of this bay will be found the White-headed Osprey 

 {Pandion leucocephalus), the Crested Hawk {Baza suhcristata), the 

 Red-backed Eish-Eagle {Haliastur girrenera, a sub-species of E. 

 Indus), the Brown Hawk (^Hieracidea orientalis), and the commonest 

 of all our Australian birds of prey. On the lower portion 

 of this case are several specimens of the Powerful Owl (Ninox 

 strenua). On entering bay No. 2, other members of the family 

 will be found, among which may be pointed out the Winking 

 Owl {Ninox connivens), and the Boobook Owl (Ninox hoohooh). 



Order PSITTAOI are exhibited in Bay No. 4. This Order 

 is well represented in Australia, from the Great Palm Cocka- 

 too, {Microglossus aterrimus) to the Little Lorikeet {Tricho- 

 glossus pusillus) ; the Cockatoos {Calyptorhynclms and Cacatua), 

 are interesting forms, but for brilliancy of plumage the 

 Red-winged Lory (Ptistes erythropterus), Barraband's Parrakeet 

 {Polytelis harrahandi), Banded Parrakeet {PlaUjcercus zonarius),
