Keel-Billed Toucan, PanamaThe keel-billed toucan is one of the most colorful birds of the Central American rainforest, instantly recognizable by its large bill in bright greens, oranges, reds, and blues. Despite its size, the bill is surprisingly lightweight, made mostly of hollow bone covered in keratin. Keel-billed toucans use it to reach fruit on slender branches, but they’ll also eat insects, lizards, and even small birds’ eggs. This one was photographed in Soberania National Park in Panama. Nikon D810 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/200th of a second.
