生长繁殖 Growth and Breed黑腹树鸭是忠于一夫一妻制的,一般会一同生活很多年。这种特性通常与鹅和天鹅有关。雄鸟及雌鸟会分担孵化至喂养雏鸟的工作。它们喜欢在空心树中筑巢,但有时也会在地上筑巢。它们也会到烟囱、弃置的建筑物、巢箱等筑巢。近几十年来,后者越来越多地被提供给它们,特别是在德克萨斯州东南部和墨西哥。雏鸟在孵化后两天就可以离开巢穴,并能自行觅食,最多会与父母同住八周之久。
黑腹树鸭的英文介绍 IntroductionThe black-bellied whistling duck (Dendrocygna autumnalis), formerly called the black-bellied tree duck, is a whistling duck that breeds from the southernmost United States, Mexico, and tropical Central to south-central South America. In the US, it can be found year-round in peninsular Florida, parts of southeast Texas, coastal Alabama and seasonally in southeast Arizona, and Louisiana's Gulf Coast. It is a rare breeder in such disparate locations as Arkansas, Georgia, Tennessee, and South Carolina, though it is now a common breeder in parts of central Florida. There is a large population of several hundred that winter each year in Audubon Park in uptown New Orleans, Louisiana. Since it is one of only two whistling duck species native to North America, it is occasionally just known as the "whistling duck" or "Mexican squealer" in the southern USA.在神秘的大自然面前,我们无知的像个孩子......
