Description: It is a medium-sized heron with a compact body and relatively short neck, showing mostly white plumage. During the breeding season, it develops buff to orange ornamental feathers on the head, chest, and back, giving it a distinctive appearance. The bill is strong and yellowish, and the legs are shorter than those of most herons, often turning reddish during courtship. Sexes are similar, with males slightly larger.

Geographic distribution: It has one of the widest distributions among herons, occurring on all continents except Antarctica. In the Americas, it ranges from the southern United States through much of South America, including most of Argentina. Its remarkable expansion ability has allowed it to colonize new areas rapidly.

Habitat: It commonly inhabits grasslands, agricultural fields, savannas, pastures, open wetlands, and rural landscapes, showing a strong preference for terrestrial habitats rather than aquatic ones. It is frequently seen near livestock and farming activities.

Feeding: The diet is mainly insectivorous, consisting of grasshoppers, crickets, beetles, and other arthropods, but it also takes small vertebrates such as frogs, lizards, and rodents. It often exploits disturbed ground caused by cattle or machinery to capture prey.

Behavior: This is a highly social and approachable species, usually feeding in groups and roosting in flocks. Unlike many herons, it spends much of its time walking on dry ground. Outside the breeding season, it may travel long distances in search of food, showing a very opportunistic behavior.

Nesting: It nests colonially, often alongside other heron species and waterbirds. Nests are built with sticks in trees, shrubs, or reed beds. The clutch usually consists of 3 to 5 eggs, incubated by both parents, who also share chick rearing duties.

Conservation status: It is classified as Least Concern, with large and expanding populations. Its success is closely related to its high adaptability to human-altered environments, although in some regions it may be considered overly abundant.
