Beginning in the Sonoran Desert and finishing in Ecuador's mountaintop preserve of Loma Alta, this episode examines the life of the hummingbird. Southern Arizona is the perfect place to start, as it lays along the migratory route for these "winged jewels" and makes for an ideal place to study birds that come from as far away as British Columbia and Alaska. Then host David Yetman climbs to the mountaintop preserve of Loma Alta to join scientists as they research "hummers" found in the fog forest. Observe some of the unusual and gentle methods researchers use to study these delicate creatures. This program also features a close-up look at howler monkeys.
