Masked Weaver, Queen Elizabeth National Park, UgandaThis masked weaver was in the early stages of building its nest. That ring of grass will eventually be an intricate orb dangling from the branch. Photographed on my first trip to Uganda when I went to Queen Elizabeth National Park. Nikon D300 with Nikkor 200-400mm lens (at 400mm) ISO 200, f/5.6 at 1/800th of a second.
