Sunbirds

A million years ago, the soundtrack of the "sky island" mountains of East Africa may have been very similar to what it is today. | These colorful, tiny, nectar-feeding birds are called sunbirds. | They resemble hummingbirds and are common throughout Africa and Asia. | That's because a group of tiny, colorful birds has been singing the exact same tunes for more than 500,000 years. | The most famous eastern double-collared sunbirds, also known as the "sky island sunbirds," live at the peaks of tall mountains in East Africa from Mozambique to Kenya.
