“Outback birds need regular water, and many of these are thriving. Those doing better than ever include zebra finches, wood ducks, Bourke's parrots and possibly emus. On the other hand many insect-eaters are doing badly, because grazing stock destroy the plants on which insects breed. Seed-eaters themselves suffer when grasses are grazed too low to set seed. Dams create plenty of losers as well as winners, and that's something to keep in mind.” NatureEnvironmental Change Book:Radio Volume 2 Source: Radio Volume 2
“Foreign leaves feed many a marsupial, grub and duck. Koalas often munch on American cypress pine needles and camphor laurel leaves. (They also like to perch in camphor laurels in summer for the cool shade they throw.) Exotic foods, and I don’t just mean weeds, are thoroughly enmeshed in foodwebs. Most Australia’s birds of prey take exotic meats. A study around Mildura found that young rabbits were the staple food (60-92 percent by weight) of eagles, goshawks, harriers, kites and falcons – eight species in all. That was be calicivirus struck. Wedge-tailed eagles will eat feral cats. In Western Australia little eagles moved into the south-west when rabbits arrived, then retreated after myxomatosis struck. House mice feed hawks, snakes and owls in central Australia, making up to 97 percent of barn owl diets.” EcologyNovel EcosystemsFoodwebs Book:Radio Volume 2 Source: Radio Volume 2
