New Species of Giant Hummingbird Discovered After Centuries

Researchers differentiate two distinct species with unique migration patterns using innovative tracking devices.

The northern giant hummingbird lives year-round in the Andes, while the southern giant hummingbird undertakes a 5,200-mile migration.
Tiny geolocator backpacks helped scientists track and distinguish the two species.
The discovery resolves a mystery dating back to Charles Darwin's observations in 1834.
The two species have evolved separately for about 3 million years, with significant differences in physiology and behavior.
Researchers aim to further study how these species interact and their coevolution with local flora.
