.(11) Long Hops: Making sense of bird migration

Birding has been a hobby of mine since childhood. Here I get to tell you the astonishing stories of bird migration, and explain the research that has uncovered it. (The longest non-stop migration flight discovered so far is from Alaska to New Zealand--over 11,000 km!) Only recently have scientists learned of the many and varied ways that birds navigate long migration journeys, for example. Bird navigation, the physics of bird flight, and the reasons why birds migrate, are explained in non-technical language.
