Abstract
In 24th May 2022, the presence of one adult specimen of White-faced Whistling-Duck Dendrocygna viduata (Linnaeus, 1766) (Aves Anatidae) was recorded in the sewage treatment lagoon of Al-Saket, in Misrata city about 200 km east to Tripoli (32°19’11.0”N 15°00’48.3”E), Libya. It was found swimming on water surface of the lagoon. Dendrocygna viduata breeds in sub-Saharan Africa and much of South America and is considered as gregarious and vagrant species. This is the first record of D. viduata in Libya that requires further confirmation as only one specimen has been observed and being a duck subject to human breeding. KEY WORDS White-faced whistling duck; Alsaket sewage treatment; Misrata; Libya.
