Birds and Global Climate Change: Evidence from the Past Provides Clues to the Future

Travel throughout the Americas and explore how environmental changes affect avian biodiversity. Garth Spellman, DMNS curator of ornithology, takes you to Central America to see how global cooling during the Pleistocene allowed house wrens to become the species with the largest range in all of the Americas, from southern Chile to the Canadian subarctic! Soar above the Rocky Mountain and western North America to examine how these same ice ages enabled new species to spread across this dynamic landscape, and to the Black Hills of South Dakota, where Virginia’s warbler has recently expanded its range. Conclude with a discussion of how current global warming is affecting birds.
