美洲紅鸛 俯瞰正在飛越洛斯羅克斯群島國家公園的美洲紅鸛 今天是拉丁美洲和南美洲的世界候鳥日，為了紀念這一天，我們選擇了這些在委內瑞拉海岸外加勒比海上空的美洲紅鸛。白天時間和食物供應的變化會引發(fā)包括美洲紅鸛在內的許多鳥類的季節(jié)性遷徙。像這樣的美國美洲紅鸛遷徙距離相對較短，通常是為了確保穩(wěn)定的食物供應。它們主要分布在加勒比海地區(qū)，分布范圍從北到南佛羅里達州世界候鳥日的非營利贊助機構“美洲環(huán)境”將其工作重點放在保護數(shù)百種鳥類的棲息地上，這些鳥類在美洲從阿拉斯加和加拿大到阿根廷和智利沿南北路線遷徙以及介于兩者之間的地方。這些候鳥中的大多數(shù)都使用已建立的稱為飛行路線的飛行路線在它們的繁殖地和越冬地區(qū)之間旅行。這些空中公路往往避開山脈和海洋等障礙物，與地形障礙物平行，沿著海岸或主要河谷的路線行駛。在北美遷徙的鳥類沿著大西洋、密西西比、中環(huán)和太平洋四條主要航線遷徙。由于鳥類在沿途的中途停留點需要足夠的食物和庇護所，通過這些走廊保護棲息地對鳥類的生存尤為重要。今年，隨著野火肆虐美國西部，太平洋航線尤其危險，而10月10日是墨西哥、中美洲和南美洲的世界候鳥日，美國和加拿大的鳥類愛好者在5月的第二天慶祝這一保護活動。但無論你住在哪里，每天都是拿起望遠鏡，在自己的窗外觀察鳥類的好日子。

英語原文:

Today is World Migratory Bird Day in Latin and South America, so to honor the occasion we've chosen these flamingos, rising above the Caribbean Sea off the coast of Venezuela. Changes in daylight hours and food availability can trigger seasonal migrations in many bird species, including flamingos. American flamingos like these will migrate relatively short distances, usually to ensure a steady food supply. Found mainly throughout the Caribbean, their range extends as far north as southern Florida.The nonprofit sponsor of World Migratory Bird Day, Environment for the Americas, focuses its efforts on conserving habitats for the hundreds of bird species that migrate along north-south routes in the Americas, from Alaska and Canada to Argentina and Chile and places in between. Most of these migratory birds use established flight paths called flyways to travel between their breeding grounds and overwintering areas. These aerial highways tend to avoid obstacles such as mountain ranges and oceans, running parallel to topographical barriers and following routes along coasts or major river valleys. Birds migrating through North America follow four main flyways, the Atlantic, Mississippi, Central, and Pacific. Because the birds need adequate food and shelter at stopover points along the way, conservation of habitats through these corridors is especially important to the birds' survival. This year, with wildfires raging across the American West, the Pacific flyway has been especially perilWhile October 10 is World Migratory Bird Day in Mexico, Central, and South America, bird lovers in the US and Canada observe this conservation event on the second day in May. But wherever you live, every day is a good day to pick up some binoculars and watch the birdlife outside your own window.
