Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang

Inhabits a huge variety of wet environments, from lakes and marshes to coasts and flooded agricultural areas.

BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang

Patient bird that hunts by standing still in shallow water.

Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang

Usually solitary outside of breeding season, when it forms colonies.

Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang

Ambush predator that waits for prey to get close.

Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang

Carnivorous: fish, amphibians, small mammals, reptiles, and insects.

Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang

Nests in colonies in trees, often over water.

Evolutionary AdaptationsInherited traits and behaviors that improve the species' survival and reproduction in its specific environment. Multi-lang

Flexible neck: Its specialized vertebral structure allows it to perform lightning-fast strikes with its bill to capture prey.

Main ThreatsDocumented pressures reducing the population: habitat loss, hunting, disease, climate change, and invasive species. Multi-lang

Draining and degradation of wetlands, pesticide contamination, and loss of nesting sites.

Interesting FactsSurprising or notable facts that highlight what makes this species unique or ecologically important. Multi-lang

It is a symbol of conservation, as its protection at the beginning of the 20th century was key to creating the first wildlife refuges.
