松雀 松雀 今天是第120屆圣誕鳥(niǎo)類計(jì)數(shù)的第一天，據(jù)說(shuō)這是世界上規(guī)模最大、持續(xù)時(shí)間最長(zhǎng)的公民科學(xué)項(xiàng)目。在接下來(lái)的23天里，從1月5日開(kāi)始，美國(guó)、加拿大、拉丁美洲、加勒比海和太平洋島嶼的數(shù)千名志愿者將加入奧杜邦協(xié)會(huì)，共同致力于鳥(niǎo)類的研究和保護(hù)。他們一起在各自區(qū)域的森林、田野和湖泊中搜尋（或者只是觀察它們的鳥(niǎo)食者），對(duì)它們各自的鳥(niǎo)類和物種進(jìn)行普查找到。小鳥(niǎo)加拿大西部、阿拉斯加和美國(guó)西北部的觀測(cè)者無(wú)疑會(huì)發(fā)現(xiàn)一些松果喙，就像我們今天的圖片中所展示的那樣。它是真雀科中最大的一員，在北方的森林里筑巢，以漿果和水果為食。你可以從它短暫的音樂(lè)顫音中辨認(rèn)出來(lái)。雖然羅漢松主要生活在北緯，但它是一種入侵物種，這意味著它會(huì)在冬季遷徙到更遠(yuǎn)的南方尋找食物。它非常溫順，不怕人，所以很容易被忽視，因?yàn)楫?dāng)觀鳥(niǎo)者走過(guò)時(shí)，它經(jīng)常會(huì)靜靜地坐著。如果你為今年的圣誕鳥(niǎo)數(shù)做貢獻(xiàn)，即使你不留意這個(gè)美麗。

Today's the first day of the 120th annual Christmas Bird Count, said to be the largest and longest-running citizen science project in the world. For the next 23 days, through January 5, thousands of volunteers around the US, Canada, Latin America, the Caribbean, and Pacific Islands will join members of the Audubon Society for this important endeavor in the study and protection of birds. Together, they'll? scour the woods, fields, and lakes of their respective regions (or just watch their bird feeders), to take a census of the individual birds and species they find.Bird watchers in Western Canada, Alaska, and the Northwest United States will undoubtably find a few pine grosbeaks like the one featured in our image today. The largest member of the true finch family, it makes its nest in the northern boreal forests and feeds on berries and fruits. You might identify it from its short musical warble. While the pine grosbeak mostly stays in the northern latitudes, it's an irruptive species, meaning it migrates some winters farther south to find food. It's quite tame and unafraid of people, so it can be easy to overlook because it'll often sit still as a bird watcher walks by. If you're contributing to this year's Christmas Bird Count—and even if you're not—keep an eye out for this beauty.
