Habitat SummaryOverview of the specific ecosystems and environments where this species is found in Costa Rica. Multi-lang
Breeds in shallow freshwater marshes, emergent wetlands, and fens rich in cattails, sedges, and bulrushes. During migration and wintering in the tropics, it utilizes a wide variety of habitats including rice fields, mangrove edges, flooded fields, and freshwater swamp margins.BehaviourDaily activity patterns, movement, territory use, foraging style, and seasonal behavioral changes. Multi-lang
Mainly crepuscular but active throughout the day under dense cover. They walk deliberately, constantly twitching their short tails upward to display the white undertail coverts. They are solitary outside the breeding season but can gather in large numbers in prime foraging habitats like rice fields during migration.Social ActivitySocial structure: whether the species is solitary, paired, or colonial; hierarchy and communication. Multi-lang
Highly territorial on breeding grounds, defending areas with aggressive displays. During migration and wintering, territoriality decreases significantly, allowing individuals to feed within meters of each other without conflict.Feeding GuildWhat the species eats, how it forages or hunts, and its role as a consumer in the food web. Multi-lang
Terrestrial/palustrine omnivore and granivore.Trophic Chain DetailsSpecific interactions in local food webs: prey species, predators, competitors, and scavengers. Multi-lang
An opportunistic omnivore. Its diet is heavily focused on seeds of wetland plants (especially smartweeds, sedges, and wild rice) during the winter, supplemented by aquatic invertebrates, insect larvae, snails, and small crustaceans. It is preyed upon by raptors, owls, snakes, and larger wading birds.Reproductive BehaviourMating strategies, courtship displays, nesting or spawning behavior, and parental care. Multi-lang
Monogamous. Nests are built as a well-woven cup of dead vegetation attached to standing emergent plants just above the water level. The female lays a remarkably large clutch of 6 to 12 buff-colored eggs speckled with brown. Both parents incubate the eggs for 18 to 20 days. The precocial chicks are black with a unique tuft of orange chin feathers and a red bill knob; they leave the nest right after hatching.Physical Measures
