I think this is a Fitzinger’s Rain Frog, aka Fitzinger’s Robber Frog. Danta Corcovado Lodge, Osa Peninsula, Costa Rica — Rain Frogs, often also called Robber Frogs, are common all over Costa Rica. Pinning down the exact species is best left to those who really know their amphibians…which is not me. This was the first critter we encountered on our “night walk” our second night at Danta Corcovado Lodge on the Osa Peninsula. Taken by the light of a flashlight, using multi-frame noise reduction on the Sony Rx10iv at 600mm equivalent. Program mode with wildlife modifications and multi-frame noise reduction. Processed in Pixelmator Photo and Apple Photos. Equivalent ISO 4000 @ f4 @ 1/500th.
