Ringed Kingfisher, Costa RicaA ringed kingfisher doing what ringed kingfishers (and all kingfishers) do. Diving for a fish. I captured this one on a boat excursion through the mangroves of Piedras Blancas National Park in Costa Rica. Nikon Z8 with Nikkor 500mm PF lens, ISO 900, f/5.6 at 1/2500th of a second.
