Habitat and Ecology
This is a widespread, nocturnal species that occurs in many habitats including open grassland, flooded savannahs, and pastureland. It breeds in cattle ponds or temporary waterbodies such as puddles, often in water-filled hoof tracks. The eggs are laid in foam nests, attached to grass stems at the margin of the pond. It is a very adaptive species.
It is common throughout much of its range.
It is not threatened overall. It is locally threatened in Argentina by the destruction of Chaco habitat for agriculture and wood extraction, land and water pollution caused by agrochemical runoff.
Its range includes several protected areas.
Red List Status
Least Concern (LC)
Listed as Least Concern in view of its wide distribution, tolerance of a broad range of habitats, presumed large population, and because it is unlikely to be declining to qualify for listing in a more threatened category.
