  ABSTRACT
  The Black Swan Cygnus atratus (Latham, 1790) (Aves Anatidae) is native to Australasia and is widely kept in captivity outside its natural range. In recent decades, feral and escaped individuals have been increasingly recorded in Europe, the Middle East, and North Africa. Here we report the observation of a Black Swan at Assaraya Alhamra Lake, Tripoli, Libya, on 2 February 2026. This constitutes a rare documented occurrence of the species in the country. The circumstances of the observation, behavior of the bird, and regional context are discussed, with particular attention to the likelihood of captive origin.

  Breeding of the Common Myna, Acridotheres tristis Linnaeus, 1766 (Aves Sturnidae), in Libya: evidence of nesting and range expansion
  https://doi.org/10.31396/Biodiv.Jour.2025.16.4.593.596

  ABSTRACT
  The Common Myna, Acridotheres tristis (Linnaeus, 1766) (Aves Sturnidae), one of the world’s most invasive avian species, was first recorded in Libya in June 2024. Since then, field observations have confirmed not only its establishment but also active breeding across multiple Libyan regions. We report the first documented nesting of Common Myna in Libya, with confirmed breeding sites in the eastern (Amsaid, Tobruk, Benghazi) and western (Tripoli) regions. These findings demonstrate successful colonization and raise urgent concerns regarding the species’ ecological impact on native birds and biodiversity in North Africa. Immediate monitoring and management strategies are recommended to prevent further spread.
