“…Likewise the diet of the barn owl in Victoria consists mainly of small mammals, although it has also been recorded preying on small birds, insects, lizards and frogs, and its nest is usually a tree hollow [33]. Brown goshawks construct stick nests high in mature Eucalyptus trees [34]. Birds made up 63 % of the prey items of the brown goshawk in a study in Victoria, with mammals, reptiles, insects and crustaceans composing the remainder of their diet [35].…”

Purpose. Beak and feather disease virus (BFDV) is a circovirus and the cause of psittacine beak and feather disease (PBFD). This disease is characterized by feather and beak deformities and is a recognized threat to endangered Psittaciformes (parrots and cockatoos). The role that non-psittacine birds may play as reservoirs of infection is unclear. This study aimed to begin addressing this gap in our knowledge of PBFD.Methodology. Liver samples were collected from birds presented to the Australian Wildlife Health Centre at Zoos Victoria's Healesville Sanctuary for veterinary care between December 2014 and December 2015, and tested for BFDV DNA using polymerase chain reaction coupled with sequencing and phylogenetic analyses.Results/Key findings. Overall BFDV was detected in 38.1 % of 210 birds. BFDV was detected at high prevalence (56.2 %) in psittacine birds, in the majority of cases without any observed clinical signs of PBFD. We also found that BFDV was more common in non-psittacine species than previously recognized, with BFDV detected at 20.0 % prevalence in the non-psittacine birds tested, including species with no clear ecological association with psittacines, and without showing any detectable clinical signs of BFDV infection.Conclusion. Further research to determine the infectivity and transmissibility of BFDV in non-psittacine species is indicated. Until such work is undertaken the findings from this study suggest that every bird should be considered a potential carrier of BFDV, regardless of species and clinical presentation. Veterinary clinics and wildlife rehabilitation facilities caring for birds that are susceptible to PBFD should reconsider biosecurity protocols aimed at controlling BFDV.

“…fasciatus are associated with migration (Wattel, 1973). Although at least partial migration has been recorded for A.fasciatus (Aumann, 1986), long pointed wings are not a necessa ry prerequisite for migration , as shown by migratory Accipiter genii/is and A . nisus (Cramp & Simmons, 1980).…”

“…Accipiter fasciatus , with proportionally longer wings, alula and tail than A . novaehollandiae, possesses characteristics of species that inhabit open country and undertake extended flights at speed (Wattel, 1973;Aumann, 1986 ). It has also been suggested that the longer, more pointed wings of A .…”

“…The suggestion that nominate A.ffasciatus may overwinter in the tropical north was made by Condon & Amadon (1954), Storr (1984) and Aumann (1986). Ford (1986) suggested that the distribution of A.ffasciatus might permanently overlap that of A.f didimus, and that they might thus be separate species.…”

Morphometric comparison of two sympatric goshawks from the Australian wet tropics

Sympatric populations of the grey goshawk Accipiter novaehollandiae and the brown goshawk Accipiter fasciatus were studied in the wet tropics of north‐eastern Australia. The morphology of A. novaehollandiae suggests that it is adapted for life in dense forest, while that of A. fasciatus indicates that it should favour open woodland. The species differ in the shape of the wing and the size and shape of feeding structures. The wings of A. novaehollandiae are relatively short and broad, its bill and talons are more robust and its tarsi are relatively short and thick. It appears to be adapted to feed on medium‐sized mammals and reptiles and on larger birds such as pigeons and megapodes. A. fasciatus has relatively longer and narrower wings, allowing greater speed in open habitats. Its more delicate bill and longer tarsi are characters typical of bird‐eating accipiters.
