SUMMARY:Islands And Avian Evolution
DESCRIPTION:Featuring Bob Lewis \nThursday\, August 19 – 7 p.m. \nEastern Crested Berrypecker\,\na New Guinea endemic\, by Bob Lewis\nIslands play a key role in both the evolution of new avian species and the extinction of others. Because of their isolation\, birds that arrive on islands evolve separately from their parent group and eventually become unique… thus a new species is born!  But that isolation also makes them vulnerable to threats like hurricanes\, volcanoes\, rising seas\, and introduced diseases or predator species. Although over 80 percent of bird species live on continents\, 92 percent of extinctions since 1500 have been on islands. Join Golden Gate Audubon Society to view some marvelous island species and learn about the conservation issues unique to islands. \nPlease click the link below to join the webinar:\nHTTPS://ZOOM.US/J/91784420140?PWD=ETYZDTDIEEJLVETVYLJHVVNIMDN2DZ09\nPasscode: 493526 \nA video recording of this presentation will be available for three weeks after the talk. \nAbout the speaker: \nBob Lewis has taught birding classes in the Bay Area for over 25 years and loves to travel\, especially to islands in search of birds.  He is a board member of the Farallon Islands Foundation\, created to foster life on islands.  Bob has visited many of the larger islands populated with unique species\, including Madagascar\, Borneo\, Hawaii\, Indonesia\, New Guinea\, New Zealand\, Cuba etc.  The talk will be illustrated with his photos of birds from these places.
