▶️ Rivoli's Hummingbird (4K UHD)
Premiered Jan 4, 2021
A big, long-billed hummingbird of forests in the southwestern mountains. Almost as large as the Blue-throated Hummingbird found in the same ranges, the Rivoli's is not usually so aggressive or conspicuous, but some individuals are very pugnacious in defending flower patches or feeders, even fighting with the Blue-throat at times. In hovering flight, the wingbeats are almost slow enough for the human eye to see.
