Mexican Hairy Porcupine, Costa RicaThe Mexican hairy dwarf porcupine is a slow-moving, nocturnal rodent that spends most of its life high in the rainforest canopy. In Corcovado National Park, sightings are rare, as these elusive climbers move quietly through the trees under cover of darkness. I obviously caught this one up past his bedtime for a rare daylight photo op. Nikon D800 with Nikkor 200-400mm lens (at 400mm) ISO 1600, f/4 at 1/60th of a second.
