The Yellow-footed Gull, *Larus livens*, is a striking, large gull endemic to the Gulf of California, a true jewel of arid coastal ecosystems. Measuring 53–66 cm (21–26 in) in length with a wingspan of 130–148 cm (51–58 in) and weighing between 900–1500 g (2.0–3.3 lb), this robust species stands out with its exceptionally dark slate-gray mantle and upperwings, contrasting sharply with its bright white head, underparts, and tail. Its most distinctive field mark, providing its common name, is it...
Exclusively found in marine and coastal environments, the Yellow-footed Gull thrives on rocky islands, sandy beaches, salt lagoons, and arid mainland shorelines of the Gulf of California. It is typically found at sea level, rarely venturing inland.
An omnivorous and highly opportunistic scavenger and predator, its diet includes a wide array of marine organisms such as fish, crustaceans, mollusks, and squid, along with seabird eggs and chicks, carrion, and human refuse. They primarily forage by patrolling coastlines, scavenging, and shallow ...
The Yellow-footed Gull exhibits a highly opportunistic and social behavior pattern, spending its days foraging and interacting within its coastal domain. During the breeding season, these gulls form dense, noisy colonies on remote islands and mainland coasts, where pairs establish and vigorously ...
The Yellow-footed Gull is largely endemic to the Gulf of California, Mexico, with its primary breeding range concentrated on numerous islands and the arid mainland coasts within this region, particularly in Baja California Sur, Baja California, and Sonora. During the non-breeding season, while ma...
