“[Hummingbirds] are the very only group of birds in the world that can fly not only forward, normal, but up, down, and backwards,” says Diego Calderón Franco, one of Colombia’s most famous birding guides. Colombia is home to more than 160 species of hummingbirds. They can beat their wings up to 80 times per second, Franco explains. #birding #birdwatching #hummingbird
