A medium-sized heron with a robust, stocky silhouette that sets it apart from the other herons. The adult has a jet-black back, gray wings, a white belly and a white band from the forehead to the nape, from which hang two or three long white plumes in the breeding season. Its eyes are blood-red and very striking. Juveniles have a completely different plumage: dark brown with white spots and streaks that make them unrecognizable to the unfamiliar observer. It measures 58 to 65 cm.
Behaviour
Strictly nocturnal and crepuscular. By day it shelters in dense groups within the riverbank vegetation. At sundown, groups of dozens or hundreds of individuals set off for their fishing areas, giving a characteristic deep, hoarse "quoc." It fishes in shallow water: fish, frogs, shrimp and aquatic insects.
How and when to see it
At dusk, when the flocks emerge from their roosts and cross the sky toward the wetlands. The boardwalks of Portal Laguna Iberá at nightfall are an excellent observation point.
