The article presents information on extinction of rare and endangered species. David Luneau, a computer and electronic professor, took some images of a crow-sized bird perching on the trunk of a tupelo tree that was last seen in the United States 60 years ago. Since then, numerous search parties have been launched to comb that patch of forest for more evidence of the bird's existence. Only a few of those 1.5 million described species are known and About 130 kinds of birds have vanished around the world over the past century and a half. Biologist Stuart Pimm said that habitat destruction was the major cause of species loss. The World Conservation Union currently lists 1,213 birds as threatened, about 12 percent of all avian species. According to a Nature Conservancy study, dragonflies and beetles are more highly threatened than birds in North America. A study shows that 71% of butterfly species declined over the course of the study, compared to 54% of birds and 28 percent of plants. About 15-37% of the species would be on their way to extinction by 2050.
