山地藍(lán)知更鳥 黃石國家公園里的一只雄性山地藍(lán)知更鳥 歡迎回來，小藍(lán)知更鳥。盡管這個聰明的家伙可能正在黃石國家公園忍受今年最后一場雪，但他的出現(xiàn)意味著美國的冬天即將結(jié)束。在許多文化中，藍(lán)鳥是幸福的象征，是春天受歡迎的象征。不久，其他候鳥也將抵達(dá)大黃石生態(tài)系統(tǒng)——這是一塊700萬公頃的土地，包括大提頓國家公園和周圍的國家森林。它是世界上最大的完整的北溫帶生態(tài)系統(tǒng)。這到底是什么意思呢?自從25年前狼被重新引入黃石公園以來，歐洲探險者首次記錄下來的所有動物物種至今仍能在這里找到。

英語原文:

Welcome back, little mountain bluebird. Although this bright fellow may be enduring the last of this year's snow in Yellowstone National Park, his presence means winter will soon be ending. Bluebirds are a symbol of happiness and a welcome sign of spring in many cultures. Soon other migratory birds will arrive in the Greater Yellowstone Ecosystem—an 18-million-acre tract that includes Grand Teton National Park and surrounding national forests. It's the world's largest intact ecosystem in the northern temperate zone. What exactly does that mean? Since wolves were reintroduced to Yellowstone 25 years ago, all the animal species that were first documented by European explorers can still be found here.
