波士顿大学观鸟指南

混凝土。沥青。砖。这座城市不是野生动物的自然栖息地，但在波士顿可以找到各种形状、大小和颜色的鸟类。事实上，波士顿大学全年有 100 多种鸟类造访校园。它们是“我们周围最后一个真正的野生物种。最后一次大迁徙，“奎斯特罗姆商学院教授、狂热的观鸟者安德鲁·金说。而且，他说，“城市地区有时比农村地区更好。如果你仔细观察，波士顿大学的校园——查尔斯河、芬威和医疗——是一系列令人难以置信的鸟类的家园。

近年来，游隼在宿舍筑巢，红尾鹰在法学院的楼顶上舒适地栖息，野生火鸡在街上漫游。形成查尔斯河和芬威校区自然边界的水道为水禽和迁徙鸣禽提供了理想的栖息地。

近年来，观鸟作为一种爱好越来越受欢迎——这一趋势被广泛归因于大流行迫使社会疏远和越来越多的人在家工作。人们注意到家周围环境的节奏，并寻求自然户外空间的安全。国家奥杜邦协会的杂志 《奥杜邦》报道称，2020 年上半年鸟籽的销量猛增。每年5月举行的国际观鸟活动“全球大日”（Global Big Day）已连续四年创下参与记录。BU 的学生、教职员工、教职员工和校友已经找到了自己的方式来欣赏周围的荒野。

这些只是波士顿大学社区欣赏波士顿鸟类的几种创造性方式。自 2000 年以来，eBird 应用程序上的观鸟者报告了 BU 校园内的 145 种鸟类，从常见的（加拿大鹅和鸽子）到稀有的（威尔逊莺和黄嘴杜鹃），反映了整个大学的非凡生物多样性。

BU Today 邀请狂热的 BU 观鸟者分享有关何时、何地以及如何开始在校园观鸟的提示。

The cedar waxwing is a medium-sized, sleek songbird with a large head, short neck, and short, wide bill. It has a distinctive crest that often lies flat and droops over the back of its head. The wings are broad and pointed, and the tail is fairly short and square-tipped. The cedar waxwing has a black mask around its eyes, a tan head and breast, a yellow belly, and grayish-brown upperparts. The tail has a yellow band at the tip, and some of the wing feathers have waxy red tips that give the bird its name. Juveniles are more heavily marked than adults, with dusky streaks below and a fainter dark mask. Some birds may also be less intensely colored and lack the red feather tips in the wings. Cedar waxwings are known for their acrobatic foraging, often perching at the tips of thin branches to feed on berries and other fruits. They frequently gather in large flocks, especially during the fall and winter months when they can be seen devouring fruit wherever they can find it.
