White Tufted-Ear Marmoset, BrazilThese little primates are about the size of a common gray squirrel. That is to say, very small. A troop of them came through our camp one afternoon, hung around for a minute or two and then moved deeper into the forest. Like yesterday’s post, this one was photographed in the Hyacinth Valley of central Brazil. Nikon D300 with Nikkor 200-400mm lens (with 1.4 teleconverter for 550mm) ISO 800, f/5.6 at 1/160th of a second.
