There will be only the single presentation this month by Jerry Olsen, a member of the Institute for Applied Ecology at the University of Canberra, on ACT Raptors.
14 raptor species breed in or near the relatively small confines of the Australian Capital Territory. Many breed in the city. How do these 14 raptor species divide up different habitats, and mammal, bird, fish, reptile and invertebrate prey so there isn’t too much overlap in prey species taken? Why do some ACT raptors catch prey species said not to exist in the ACT? Why are Powerful Owls different from other ACT raptors? This talk is a slightly revised version of a talk given in 2015 at the Australian National Botanic Gardens.
Jerry Olsen has presented to COG many times. He has authored or co-authored about 100 research papers and six books on Australian raptors. Australian High Country Owls and Australian High Country Raptors (2011 and 2014, CSIRO Publishing) are about ACT raptors.
