Abstract:

Lesser White-fronted Goose (Anser erythropus) is globally classified as Vulnerable and one of the rarest goose species recorded in Türkiye. Despite its status as a regular but scarce winter visitor, systematic monitoring is absent, and knowledge relies mainly on citizen science observations and limited telemetry data. To assess the species’ wintering distribution and threats in Türkiye, records from citizen science portals were compiled and filtered for duplicates. Confirmed observations were obtained for 26 wetlands. Lake Erçek in Eastern Anatolia was identified as the only regular wintering site, while Lake Haçlı was identified as a potential regular wintering site; other wetlands hosted only irregular records. The largest flock—1,234 individuals—was reported from Lake Haçlı in 2021; however, insufficient monitoring prevents classification of the site as a regular wintering area. Poaching may represent the most severe threat. As both major Western Palearctic flyways intersect Türkiye, the conservation of key eastern wetlands, particularly Erçek and Haçlı are essential. The study underscores the need for systematic monitoring and targeted conservation measures for wintering goose species.
