Crested Guan: La Selva Biological Station (OTS), Puerto Viejo, Costa Rica — There are generally Crested Guans wandering around among the buildings like domesticated turkeys on the grounds of La Selva. They are wary but not shy. The Crested Quan is the lowland rainforest guan of Costa Rica and is replaced by the Black Guan at higher elevations (foothills up into the lower cloud forests). It is also slightly larger, and spends more time on the ground. It is a stately bird at all times. Sony Rx10iv at 600mm equivalent. Program mode with wildlife modifications and multi-frame noise reduction (it was coming on rain and getting dark under the trees). Processed in Pixelmator Photo and Apple Photos. Equivalent ISO 5000 @ f4 @ 1/500th.
