Nightcap Nat Pk - Northern NSW

I think Peter Ekert forgets that there is a lot of altitudinal migration in northern NSW in winter. Here, a lot of birds don't go north for winter, they just go to lower altitudes. It has long been recognised that the carrying capacity of the high altitude world heritage rainforests (such as Lamington, Border Ranges, Nightcap, Washpool - all of which are about 1000 masl) are determined by the winter food resources in the lowland areas (in small rainforest remnants such as Susan Island, Iluka, Stotts Island, Booyong and other Big Scrub remnants). It gets mighty cold in the high altitude bits, and nothing much is fruiting at the moment!
