Abstract
BACKGROUND: Invasive or alien species are organisms that exist outside their natural habitat, including plants and animals. They are considered as one of the greatest threats to native biodiversity. The common Myna (Acridotheres tristis) (Linnaeus, 1766) is considered one of the most dangerous invasive or alien species. It is a carnivorous, ferocious, and strong competitor species that can mimic different voices. CASE DESCRIPTION: A pair of Mynas was observed in the Ain Zara region in Tripoli on June 19, 2024, among the houses in the area. Some locals confirmed that there is a group gathering in a garbage place near houses in the same area. CONCLUSION: The spread of invasive species remains a major threat to native biodiversity, especially the common Myna. However, it poses a threat to birds in Libya if the necessary measures are not taken to control their spread.
