Text 2 (Number 10-18)The majestic Ivory-billed woodpecker, also known as the Lord God Bird, was the largest of its tribe in the United States. This fascinating species originally roamed the pristine bottomlands and wetlands of the southeastern United States. By the mid-twentieth century, loggers had mostly devastated these famous hardwood forests, which were also home to birds ranging from the Prothonotary Warbler to the Swallow-tailed Kite. The Ivory-billed Woodpecker had vanished along with them.The Ivory-billed Woodpecker was sexually dimorphic, like many other woodpecker species, including the Red-cockaded Woodpecker and the Hairy Woodpecker. Male and female Ivory-bills were both crested, with females and juveniles having a black crest and males having a red and black crest. The species featured a long slender body and tail that was more of a pintail duck than a woodpecker. It had a distinctiveplumageas well, a glossy blue-black with white patterns on the neck and back, as well as substantial white on the trailing and front edges of the underwing.The Ivory-billed Woodpecker's call described as "kent," was a short, nasal voice. This call was often compared to the sound of a tin horn or clarinet. Another distinctive feature of this bird was a specific doubleknock sound when it hammered at trees. These double knock sounds can still be heard in Central and South America, in the forest inhabited by Ivory-billed Woodpecker relatives such as the Pale-billed, Powerful, and Magellanic Woodpeckers.Similar to other woodpeckers, the Ivory-billed had a strong. Straight bill with along. thorny tongue The flat - like - beveled - wood - chisel bill was its prominent feature, allowing it to peel the bark off dead trees whilst they searched for insects. Living up to its genus name, "Campephilus" which means "lover of grubs" the most favored insects of then ivory-billed were the large wood-boring beetle grubs. Native Americans adorned themselves with its ivory-colored bill, and bills were traded throughout North America These large birds were normally found in small numbers, even in healthy populations since they required about 10 square miles per pair to obtain enough food to feed their young.The last confirmed observation of this particular bird was heard from Singer Tract of Louisiana, which was 81,000-acre in width. A professor from Cornell, Arthur A. Allen, organized an expedition to the site in 1935. In his team were James Tanner, a graduate student, and George M. Sutton, a bird artist as well as an ornithologist and curator of the Cornell bird collection. The team captured motion picture and sound recordings of the woodpeckers. Years later, while doing his Ph D dissertation, James Tanner started to study Ivory-billed Woodpeckers and wrote an in-depth report in which he estimated only 22-24 birds remained in the United States.Since the 1940,sporadicreports of Ivory-billed Woodpeckers have surfaced, but no uncontested evidence has proved the Ivory-billed Woodpecker's continued existence in then United States The Ivory-billed Woodpecker is now classified as a class 6 species by the American Birding Association, which means itis "definitely or probably extinct" There was a Cuban subspecies of the Ivory-billed Woodpecker that was located in mountain pine forests in the northeastern section of the island, but it is now thought to be extinct owing to deforestation. According to verifiable sightings, this subspecies was last seen in the late 1980s. The Ivory-billed Woodpecker is one of 24 Western Hemisphere bird species deemed “lost" The International Union for Conservation of Nature has designated these species as Critically Endangered, which means they are not extinct but have no known surviving wild or captive populationsThe author mentions all of the following EXCEPT …
