Climate Change Threatens Bird Migrations, Habitats In San Diego County.
San Diego is a stopover point along the the Pacific Flyway migration path that stretches from South America to Alaska. It’s a crisscross this time of year, with winter flocks returning north and spring birds just arriving. More than 520 species have been documented in the county — the most in the nation, but that number is expected to decline in coming years as climate change takes hold.
