" The specific epithet is the Latin connivens 'winking'. xref Opportunistically use regions where fox control coincides with barking owl populations to examine whether increasing prey enhances owl densities. The barking owl has one of the broadest diets of any Australian owl.  These results are mirrored in the Pilliga forests of Northern NSW although there the home ranges were larger, often up to 2,500 ha (6,200 acres).. . Where poisons are used to control rabbits, secondary poisoning of owls may be an issue. , In south-western Australia a survey (in the late 1990s) of 100 forest sites found no barking owls.. The barking owl (Ninox connivens), also known as the winking owl, is a nocturnal bird species native to mainland Australia and parts of Papua New Guinea and the Moluccas.

In summary, if an animal can be detected by a barking owl and it is of its size or smaller, it can be considered as potential prey. 0000001705 00000 n Extensive surveys in Victorian forests have shown the species to be rare, localised and mainly found in north-eastern Victoria (Loyn et al. Myths surround the events that caused the owl to originally "mimic" the screaming sounds. In the early settlement of Australia a screaming noise matching the barking owl's description was credited and told to the settlers by the Indigenous Australians or the Aboriginals as the bunyip.

Growls and howls are part of a continuum of calls relating to threats, particularly during nesting. The barking owl was first described by the English ornithologist John Latham in 1801 with the binomial name Falco connivens. They also live in drier parts of Papua New Guinea and the Moluccas (Halmahera, Morotai, Bacan and Obi). 116 made under the state of Victoria, the primary threat to the barking owl is loss of habitat, particularly the deterioration or loss of the large, hollow-bearing trees on which the species depends for nesting. In contrast (as of 2012), barking owl calls are still a common sound in many wooded parts of Queensland and the Northern Territory, although there have been few recent published population studies/surveys in those areas. 0000004593 00000 n Barking calls can be varied in pitch and intensity depending on the purpose of the call. %%EOF Barking owls are not listed as threatened on the Australian Environment Protection and Biodiversity Conservation Act 1999.

Most people hear the barking owl rather than see it as it has a loud and explosive voice. 0000119808 00000 n A common theme from both research and natural resource management sectors is the need to improve understanding of this species abundance, distribution and ecological requirements.
