👕 Bird Merch — Get yourself some bird shirts!

~~~

In this episode—which is number 130—Ivan Phillipsen explores the fascinating phenomenon of vagrancy... those surprising moments when birds appear far outside their normal range.

Learn about the forces that send birds off course, including navigation errors, weather, social behavior, and more. The episode goes beyond the mystery of lost birds to ask a deeper question: are these wayward journeys simply mistakes, or can they shape the future of species?

Along the way, the episode reveals how vagrancy connects to migration, ecology, and evolution in ways that are more important than they might first appear.
