Sounds & Calls
Powerful Owl (Ninox strenua)
The Powerful Owl (Ninox strenua) is Australia’s largest species of owl. Found in forests and woodlands of south-eastern Australia, Powerful Owls are generally uncommon and have been adversely affected by land clearing. However they can sometimes be found living in urban areas (even in city parks!) and currently Birdlife Australia is sponsoring a research project aimed at gathering vital data about the behaviour of this species.
The deep, slow ‘woo-hoo’ call is diagnostic of Powerful Owl and is generally lower-pitched and more drawn out than the typical calls of the Southern Boobook (Ninox boobook). Powerful Owls also make a few other sounds including soft bleating calls, growls and young birds make high-pitched trills.
April is a good time to hear the sounds of Powerful Owls as they are entering the breeding season and often call just before dawn and just after dusk.
