This summer, we partnered with Nate Senner of the University of Massachusetts Amherst and Tebughna School in Beluga, Alaska to make this series of videos all about how, why, and where birds migrate. We had so much fun making these videos that we decided to make them available for free to anyone and everyone who is curious about the secrets birds hold. Enjoy!
Volcanoes might seem like an unstoppable force of nature - but there is at least one OTHER force on Earth that seems to be able to keep them down.
