Sooty Tern Onychoprion fuscatus

Sections

Conservation

Conservation Status

It is considered a Least Concern species globally. It has been exploited by humans for egg consumption since 1928, resulting in a decline of its populations. The main threats are the riots and destruction of nesting sites, the mortality of individuals due to oil spills, commercial fishing, and introduced mammals such as rats and cats. Hurricanes can stop any attempt at reproduction. In Seychelles, tick infestations and viruses spread by insects, caused an abnormal growth and abandonment of the chicks. Studies are needed about its ecology, reproductive biology and food, perform monitoring of the species in Mexico, and suggest strategies for its conservation.
