Whiskered Tern
Chlidonias hybridus

Reasons for the need for protection/inclusion in annex I

Whiskered Tern populations are highly unstable due to natural factors. Wetland habitat loss through the drainage of marshes and the canalization of rivers, eutrophication, the reduction in the amount of emergent and floating vegetation and disturbance due to the increasing pressure of tourism and water-sports close to breeding colonies are the major threats to the species.
