A group of renowned biologists say if nothing's done, birds could go extinct 50 times faster, eliminating about 1,200 species by century's end. The reasons: habitat destroyed by development, global warming and invasive species -- especially your cat. "If we lose species -- parrots, toucans -- our world will be a poorer place," said Stuart Pimm, a conservation biologist at Duke University.
His fears are supported by a U.S. study, released just last week, that showed 30 North American shorebird species on pace to decline by 36 percent in the next 20 years. And the subject hits close to home, where Merritt Island was the site of the most recent bird extinction in Florida and mainland America: the dusky seaside sparrow, declared extinct in 1990. Conservationists fear inland species such as the Florida scrub jay or Everglades snail kite could be next.
"Florida is losing the battle to save most bird species," said Charles Lee, a lobbyist with Audubon Florida. "I think we have an increasing challenge to all of these species as development continues to march across Florida." For most of the past 500 years, about one bird species went extinct annually across the globe. In the past few decades, conservation efforts improved the situation, with just one species on average going extinct every three years.
But if current threats persist, Pimm and his colleagues expect the extinction rate to jump to as many as 15 species a year within the next 93 years. That would threaten about 12 percent of the 10,000 known bird species.
