Do you struggle to distinguish Alder Flycatchers from Acadians, or Tree Swallows from Rough-winged?  Have trouble deciding if you’re looking at a Willow Flycatcher or an Eastern Wood-Pewee, or ID’ing Cliff and Cave Swallows on the wing (which is how you usually see them)?  With spring migration beginning, join us to get tips and tricks for identifying these aerial insectivores using field marks like tail and wingtip length as well as song mnemonics (fitz-bew!). In this interactive multimedia presentation, Matt Hayes, an avian biologist and Illinois Audubon Society’s Assistant Director, will also discuss why birds that catch their food in flight face population declines and what we can do to help save them.
