Resumen

We report a female Southern Pochard Netta erythrophthalma observed in La Tola, Esmeraldas province, Ecuador, from 19–21 March 2021. This represents the first documented record in the country since 1956. It was observed in a complex of shrimp ponds, where it associated with other waterfowl and foraged actively by diving. Identification was straightforward, excluding potentially confusing species like female Ring-necked Duck Aythya collaris. Comparative analysis suggests that it most likely involved the same individual that was recorded in southwestern Colombia in early 2020. The species is now extremely rare in Ecuador, classified as Critically Endangered. It seems extinct as resident and likely occurs only as a vagrant from eastern South America.
