CONNECT TO COUNTRY WednesdayApril 25, 2018 KATHERINETIMES 11katherinetimes.com.au Intelligent and adaptable THERE is something quintessentially Australian about the sound of a Crows caw echoing out across a sunburnt paddock. The Torresian Crow casually strolling across the highway in front of your car has an extensive distribution. Found across Australia, Papua New Guinea and some islands in Indonesia this is one bird that has benefited greatly from urban expansion and agricultural clearing. Crows arent fussy critters, theyre as happy to snack on a well weathered wallaby carcass as a juicy lawn grub or a ripe fruit. Crows are an opportunistic, omnivorous species, meaning that they are flexible enough to take advantage of any food source. They can make a home in almost every habitat within their range where there is a permanent water source. Ecologists talk about edge effects, or the changes in the structure of a community that happen at the boundary of two ormore habitats. These boundaries can allow for a rich biodiversity and fringe dwellers like the Torresian Crow are well able tomake use of such places. The numbers of Torresian Crows in Australia is increasing, possibly because they are able to take advantage of increasing urbanisation and agricultural activity. They are happy to eat human food and are very intelligent and aggressive birds and while they rarely compete with each other for food they will dominate smaller birds and steal food from large raptors. Torresian Crows were one of the first native animals to be seen successfully snacking on Cane Toads. They flip them over and eat the delicious innards and thighs, avoiding the poisonous glands at the back of the toads head. They breed between Sep tember and December, leaving large nomadic flocks to return to the same territory year after year. They defend nesting areas and care for fledglings for severalmonths, giving them time to pass on knowledge in a process called cultural transmission. This communication can be useful when a crow dies. Crows are a much maligned part of the Australian landscape but I am constantly impressed by this intelligent and adaptable bird.
