Mantled Howler Monkey, Costa RicaThe second of the three species of monkey that I saw on our recent trip to Costa Rica was the mantled howler monkey. We heard these guys every morning, but it wasn’t until our last day that I actually caught up to them (as anyone who has spent any time in the rainforest knows, howler monkeys make ferociously loud calls — among the loudest in the animal kingdom — and can often be heard from over three miles away). Funny thing was, when I finally found them, they were completely silent, just going about their morning routine high in the canopy. This one came down a bit for those fruits you can see by the left hand. Nikon Z8 with Nikkor 500mm PF lens, ISO 720, f/5.6 at 1/125th of a second.
