Boat-Billed Heron, Costa RicaWhile the boat-billed heron (Cochlearius cochlearius) is primarily nocturnal, it’s occasionally active during the day, especially in quiet, shaded wetlands where it feels safe. I’ve photographed them several times in Peru, but only at night, so it was great to capture one during the day on our recent trip to Costa Rica. Nikon Z8 with Nikkor 500mm PF lens, ISO 2000, f/5.6 at 1/1600th of a second.
