Then read each question that follows the passage. Decide which is the bestanswer to each question. Mark the letter for that answer.A Disappearing BirdThe kakapo was not always one of the raresttypes of parrot in the world. New Zealand was onceteeming with these awkward, flightless fowls.Several thousand years ago, the kakapo enjoyed anenvironment that was practically without predators.Sadly, the kakapo’s carefree lifestyle ended whenhumans began to populate the area.An Unusual BirdAlthough the kakapo is a member of the parrotfamily, it has few similarities to the parrots withwhich most people are familiar. For one thing, thekakapo is unusually large. An adult kakapo canweigh as much as eight pounds, whereas theaverage parrot weighs approximately one pound. Inaddition, the kakapo looks more like a colorful owlthan a parrot. It has a rounded head with a ring offeathers around its neck that resemble whiskers.The kakapo’s body is bulky and covered with darkgreen, black, and yellow feathers.Aside from its appearance, the kakapo has twoother traits that set it apart from other parrots. First,the kakapo is the world’s only nocturnal parrot—itsleeps during the day and hunts at night. Second,the kakapo has sizable wings but, unlike otherparrots, is not able to fly. Instead, it walks or runsfrom place to place on its strong legs. It is commonfor a kakapo to walk up to several miles each nightin search of food.The Kakapo in DangerScientists believe that the kakapo was once ableto fly. However, after living for thousands of yearsin an area without natural predators, the kakapo hadno reason to use its wings for escape. Over time,the kakapo became a bird that was quite content tostroll leisurely along the ground and climb theoccasional tree in search of food.became a problem when humans moved into thearea. When the first Polynesian settlers arrived,they hunted the kakapo for food and cut downmany of the forests in which the kakapo lived.Kakapo skins and feathers were highly valuedamong the settlers, who used them to makeclothing and bedding. To make matters worse, thesettlers brought along dangerous animals thatpreyed upon the defenseless kakapo.The discovery of the kakapo by Europeans inthe mid 1800s was the final blow to the kakapopopulation. The Europeans were so impressed bythe unusual bird that even more kakapos werekilled for the sole purpose of displaying stuffedspecimens in museums. Within a few hundredyears, the kakapo population was in grave dangerof extinction.Saving the KakapoAfter years of thoughtless kakapo hunting,people began to fear the bird’s extinction. In theearly 1950s, a conservation group began the firsteffort to save the kakapo from its seeminglyinevitable fate. For years, conservationists trackedand captured all of the kakapos they could find.The birds were transported to island sanctuarieswhere they would be safe. In the first twenty yearsof searching, fewer than ten kakapos were found.In the twenty-first century, the kakapoconservation effort is still going strong. Thanks tothe diligence of some very dedicated people, thereare over sixty kakapos in existence today!Conservationists continue to study the bird’s habitsin hopes of finding new ways to increase thekakapo population. With continued success,conservationists will undo some of the damage thathumans have inflicted upon the kakapo populationthroughout history.Unfortunately, the kakapo’s inability to flyTraits and How They Change13
