Short Stuff: Bird Migration

This episode explores the fascinating science behind bird migration, covering everything from why certain birds feel an irresistible urge to fly south to how they navigate thousands of miles with remarkable precision. Josh and Chuck break down the difference between obligate migrants, which are genetically hardwired to migrate, and facultative migrants that decide when to leave based on environmental conditions like food availability and temperature. They dive into some mind-blowing examples like Arctic terns that travel nearly 19,000 miles between poles and bar-tailed godwits that complete over 6,800 miles without stopping, plus the incredible theories about how birds navigate using everything from star patterns and the sun to their ability to literally see the Earth's magnetic field.
