Info

gullies and along watercourses are frequently used possibly because these habitatsprovide a greater diversity of prey species.(http://bird.net.au/bird/index.php?tittle:Masked_owl)Australian Masked Owls live in dry eucalypt forests and woodlands from sea level to1100 meters. Distribution extends from the coast where it is most common to the westernplains. Overall sightings fall within approximately 90% of New South Wales. Pairs havea large home range of 500 to 1000 hectares; they are territorial and remain within thesame area all their lives. In Australia they are rarely found more than 300km inland.(http://en.wikipedia.org/wiki/Tyto_novaehollandiae)Figure 3 Distribution of Tyto novaehollandiae3.3 Conservation StatusThe mainland population is declining and several states have placed the masked owl onthe species conservation status list: Least Concern3.3.1 Conservation statusFederal - VulnerableNSW - VulnerableNT - Near threatenedQLD - VulnerableSA - EndangeredTAS - Endangered12
VIC - EndangeredWA - Secure3.4 LongevityDeaths in the wild are usually a result from not having enough food or falling victim tolarger birds of prey or as result of motor vehicle accidents.3.4.1 In the WildThe lifespan of the Masked Owl has been estimated at 10 years (Bell 1996), although thisis likely to be an underestimate, given the longevity of other owl species.(www.dse.vic.gov.au)In Glenys and Derek Lloyd, Birds of Prey book, it states that most owl species live forabout 20 years.3.4.2 In CaptivityIn captivity masked owls have a greater life span than prescribed by Bell (Bell.1996)With some birds known to live past 20 years of age3.4.3 Techniques Used to Determine Age in AdultsThere is no reliable technique for aging the adults. Juvenile and adult masked owls havesimilar plumage. You could look at feather colour and condition, beak, talon colour andfeet as they may turn slightly scaly in older birds, to try and estimate a birds age,although it is best not to judge a birds age by its physical appearance as health factors canaffect appearance. Keeping records of individuals hatch date is one way to know its age.13
