Avians have been migrating between North and South America for millions of years, linking the hemispheres like only birds can do. In November 2025, people in San Carlos de Bariloche, Argentina and Aspen bridged this journey in a new way: through our Sister Cities program and our shared love of birds.

A small group of birders from the Aspen community traveled to Argentina and were hosted and guided by birders in Bariloche, facilitated through our Sister Cities relationship. In the process, they experienced a common interest through the lens of a new culture, explored iconic northern Patagonian ecosystems and the birds that inhabit them, and built bridges that promise to support an enduring connection.
