Reasons for the need for protection/inclusion in annex I
The Roseate Tern suffered a dramatic population decline through much of its EU range and it is listed as "endangered". Nesting Roseate Terns are particularly sensitive to human disturbance, egg-collection and avian or ground predators (e.g. Peregrine (Falco peregrinus), gulls, fox). Hunting in the winter quarters has been identified as a particular threat.
