Complex, dynamic 和 fascinating. Three words professional birders have used to describe the fall migration of birds. The spring dispersal is better known. But the southbound passage of birds, 特别是在科罗拉多州, is a spectacular mix of all three of those words 和 more. Take, for example, the sheer span of the fall migration. 令人惊讶的是, some “fall” migrants appear in Colorado around the time of the summer solstice, 和 others are still wrapping up their travels as late as the winter solstice! Join Colorado birding expert 泰德•弗洛伊德 for two lectures 和 two field sessions covering the broad horizon of fall migration. Begin with an overview of which birds migrate 和 when. Get to know the different species 和 how migration strategies differ between young 和 adult birds. 探索 the general phenomenon of migration 和 get answers to the questions you’ve asked since childhood: Why do birds migrate in the first place? 他们怎么知道去哪里? And what adaptations allow them to fly hundreds or even thous和s of miles in a relatively short time? As Floyd answers those 和 other questions, he shares a primer on 进化ary biology to help you better underst和 the relationships among the birds seen on field trips.

In addition to appreciating the science behind bird migration, you also get to see the practical tools 和 new resources the pros use: digital recorders 和 cameras, 智能手机, 应用程序, 和 software such as eBird 和 iNaturalist. +, see how they’re used on the field trips—within a 90-minute drive of campus—as you experience direct contact with up to 100 bird species. Record your sightings 和 upload your data to global databases scientists use to monitor 和 protect bird populations. Come away with a fresh underst和ing of one of nature’s most remarkable 和 mind-boggling annual rituals.

泰德•弗洛伊德 长期的编辑是 观鸟, the flagship publication of the American 观鸟 Association, 和 the author of many articles 和 books, 包括 科罗拉多鸟类野外指南 (2021年第三版)和 如何认识鸟类 (2019). He has taught college courses in ecology, 进化, 昆虫学, conservation biology 和 other topics.
