Исполинский уратао Nyctibius grandis

A monstrous nightbird, superficially similar to an owl but not related. Pale mottled gray with large head; larger than other potoos and lacks a dark mustache stripe. Well camouflaged and difficult to spot; most often seen roosting on a horizontal limb during the day (less often on a broken off snag like other potoos). Found in forested areas and edges. Active at night, when it feeds on large insects. Listen for its terrifying call, a harsh descending scream.
