Special needs

Caspian Terns prefer unvegetated nesting islands free of mammalian predators.

Limiting factors

Long-term availability of suitable nesting sites is important to this species. As a colonial-nester, Caspian Terns are especially vulnerable to random, human-induced, or natural events that affect colonies and productivity.

Conservation actions

Protect breeding colonies from human disturbance. The U.S. Fish and Wildlife Service's Status Assessment and Conservation Recommendations (Shuford and Craig 2002) provides additional information on appropriate conservation actions for this species.
