Hi HarryO , this is an interesting topic . I was listening to someone on the radio a while back talking about them . He was saying that they are now listed as bad as feral cats , cane toads ,and other introduced pests . After studying them they are very cleaver , they look out for one another , and signal any danger . The big problem he was saying was that they take the eggs of indigenous birds , and or kill the young . They take over areas , so the more you see of them the less you will see of the natives . I know we have a problem with them in my area . They like to nest in car ports , and roofs . They also make a mess . If I had my way they should be eradicated !!..
