In this wide-ranging talk, John Kricher will contrast the lives, ecology, and natural history of long-distance migrant passerine birds, the orioles, tanagers, thrushes, flycatchers, and wood-warblers, with passerines that are permanent residents of lowland tropical forests.  He will discuss factors that have likely resulted in some species adapting to long-distance migration and the costs and benefits that ensue.  Characteristics such as life span, clutch size, foraging behavior, habitat choice, and wing shape, all vary between long-distance migrants and tropical resident species.  This lively, thought-provoking, and thoroughly illustrated talk will explain why.

John Kricher is a Professor of Biology at Wheaton College, Norton, Massachusetts who teaches ecology, ornithology, and vertebrate evolution. His most recent book is The New Neotropical Companion (2017)
