Geoffroy's Saddle-Back Tamarin, PeruHere’s another new species for me — Geoffroy’s saddle-back tamarin, a subspecies of the brown-mantled tamarin. Tamarins are squirrel sized monkeys. They can be difficult to photograph because they’re pretty quick and usually high in trees. This one stopped for just a second to take a look down at me below in a boat. Captured in Loreto, Peru. Nikon D500 with Nikkor 500mm PF lens, ISO 1600, f/5.6 at 1/200th of a second, Godox v860iii fill flash.
