Meet the World's Rarest Gull in Galapagos
10 Jun
Summary
- Swallow-tailed gulls are the only nocturnal gulls.
- Lava gulls, the world's rarest, have charcoal-grey plumage.
- Fewer than a thousand lava gulls exist, but the population is stable.

While many tourists flock to the Galápagos for its famous finches and iconic blue-footed boobies, the islands are also home to less commonly observed seabirds. Among these are the swallow-tailed gull, unique for being the only nocturnal gull species, equipped with large eyes adapted for foraging in darkness. Visitors have reported these birds to be remarkably unafraid of humans, allowing for close observation and photography.
The archipelago hosts another endemic gull, the lava gull, which is recognized as the world's rarest. Its distinct charcoal-grey coloration provides excellent camouflage against the volcanic landscapes it inhabits. While fewer than a thousand lava gulls are estimated to exist, their population is currently stable and not considered threatened. However, like all endemic Galápagos birds, their future survival is dependent on conservation efforts amidst ongoing environmental changes.
