Mary Whitfield has spent two decades studying one of North America’s rarest birds: the Southwestern Willow Flycatcher. At her research sites in California, populations have dwindled significantly. Saving these birds is a challenge because they migrate to Latin America in the winter, so Mary has joined the Bird Genoscape Project, bringing together researchers from all over the Americas in an effort to protect the birds that unite the hemisphere.
