“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
