Black-Shouldered Antshrike, Costa RicaAfter doing my research, I realize there’s not a lot written about the black-shouldered antshrike. What I can tell you — it’s small, it’s black, it has little white spots and it was photographed in Corcovado National Park in Costa Rica. Nikon D800 with Nikkor 200-400mm lens (at 400mm) ISO 3200, f/4 at 1/160th of a second.
