  • Threatened Wildlife Photographic Competition
    THREATENED WILDLIFE PHOTOGRAPHIC COMPETITION Winners Announced The Australian Wildlife Society Threatened Wildlife Photographic Competition is a national competition that awards and promotes endangered Australian wildlife through the medium of photography. The Australian Wildlife Society invited photographers to raise the plight of endangered wildlife in Australia. Our Society aims to encourage the production of photographs taken in Australia, by Australians, which reflects the diversity and uniqueness of endangered Australian wildlife. The annual judge’s prize of $1,000 was won by Native Animal Rescue of Western Australia (Mike Jones, Black Cockatoo Coordinator). The winning entry was a photo of a forest red-tailed black cockatoo named Makuru. The forest red-tailed black cockatoo (Calyptorhynchus banksia naso) is listed as Vulnerable; only two of the five subspecies of black cockatoo are listed as Threatened on account of habitat destruction and competition for nesting hollows. The photograph was taken in Native Animal Rescue’s Black Cockatoo Facility (opened 2011 thanks to a generous grant from Lotterywest), which allows them to receive and care for injured or ill black cockatoos. Makuru (a Nyungar word meaning The First Rains or Fertility Season) was the first captive-born black cockatoo at the facility in July 2016. The photo depicts the young cockatoo emerging from its breeding hollow at two months and 15 days. Thank you to all the contributors to the Society’s inaugural Threatened Wildlife Photographic Competition – please enter again next year. Australian Wildlife Vol 4 - Spring 2017 7 The annual people’s choice prize of $500 was won by Matt White Matt’s entry was a photo of a greater glider (Petauroides volans).

But can novel environments reveal plasticity by causing a shift in a behavior as fundamental and conspicuous as daily activity? We studied daily activity times near the invasion front of the cane toad (Rhinella marina), an invasive species that has colonized much of northern Australia. Cane toads in Australia are nocturnal, probably because diurnal activity would subject them to intolerably hot and dry conditions in the tropical savannah during the dry season.
