Mini-Tutorial: The Perils of Migration

Bird migration has been taking place for hundreds of thousands of years, but in recent times birds have met with many more challenges than evolution may have bargained for. Denis Kania takes us through the benefits and hazards of bird migration, noting strategies different bird families use, plus major flyways, broad front migration, and natural obstacles. Through the incredible tale of the tiny Blackpoll Warbler, we learn of birds' hormonal changes and fat storage, the timing of migration, and the energy equation.
