The conditions that produce large episodes of bird migration are common knowledge to many temperate birders: cold fronts push birds south in the fall, while warm fronts push them north in the spring. But what happens when the neotropical migrants we enjoy in Chicago reach South America and these large weather systems downsize to local climates over a complex landscape? How do climate and geography like the Andes Mountains change how birds migrate through the tropics and promote the evolution of migratory flyways? Jacob Drucker, a research associate with the Field Museum, will discuss his attempts to answer these questions using weather surveillance radars in Colombia, and the implications for developing effective conservation strategies across birds’ annual cycles.
