Abstract

We report new records of the Dot-winged Crake Porzana spiloptera in southern Chile, an almost unknown species distributed mainly in Argentina and recently discovered in Chile. The occasional capture of a juvenile of the species at Cruces River wetland (39°S), and the analysis of sound recordings obtained to explore the acoustic attributes of urban wetland soundscapes, made it possible to discuss the status of the Pacific populations of the species. The new records show that P. spiloptera has a resident status and suggest that the presence of the species in Chile went historically unnoticed, and that it has been confused with the Black Rail Laterallus jamaicensis. Comprehensive surveys and dedicated research that provide fundamental biological aspects such as the current distribution, population abundance, habitat requirements, and main threats for these secretive rails are urgently needed for their conservation. © 2023 Neotropical Ornithological Society.
