Economic Importance and Threats
Threats:  Anthropogenic
(Some populations of this species have significantly declined due to decreasing food availability caused by competition and predation from Larus argentatus and Larus marinus and by changes in fishing and refuse disposal practices (e.g. closure of landfill sites and the covering of waste). Population declines may also have been aided by poisoning from organochloride pollution. Contamination from pesticides is no longer considered a likely threat. )
Threats:  Natural threats
(The species is susceptible to avian botulism, so may be threatened by future outbreaks of this disease.)

Habitat:  Estuarine, Coastal
Trophic Level:  Consumer
Prey:  Omnivorous, consist of small fish and aquatic and terrestrial invertebrate
IUCN Status:  Least Concern
