Birds & Islands with Bob Lewis: Program 3 of 4. Sahul - A Paradise for Birds
With a series of four talks about four very different island habitats, we’ll explore the importance of islands to avian evolution, including speciation and extinction. As islands form, birds arrive and establish unique island populations. Over time, they may evolve into new species, flourish in the absence of predators, or die off due to the impact of hurricanes or newly introduced predators. We’ll look at a number of island endemic birds, talk a bit about geology and island formation, and consider the impact of man on bird survival.
Sahul - A Paradise for Birds
Australia, New Guinea and Tasmania are all part of the Australian geological plate, or Sahul. After a brief visit to O’Reilly’s, a wonderful jungle lodge near Brisbane, Australia, we’ll fly to Port Moresby, the capital of Papua New Guinea. Our route in PNG will take us from the lowlands in the south of the island to the highlands on the western border, and then on to Mount Hagen, a 12,000’ extinct volcano. New Guinea has 708 species of birds and 5 endemic families and is home to most species of spectacular Birds of Paradise and fascinating Bowerbirds. We’ll discuss a bit of geological history, a bit of taxonomy, and look at examples of many of PNG’s 70 bird families.
