Flame Rumped Tanager, La Selva, Costa RicaThis guy is worth the post for the name alone. From the front, these birds appear uniformly black, but when at the right angle, and if they move their wings out of the way, that flame rump can be spectacular. Photographed in La Selva, Costa Rica. Nikon D800 with Nikkor 200-400mm lens (at 350mm) ISO 800, f/4 at 1/125th of a second.
