Gaviota de cola bifurcada
The swallow-tailed gull is the only species in the genus Creagrus, which comes from the Latin and Greek words for butcher or meat. It is thought that this refers to their hooked bill, reminiscent of a butcher’s hook.
They are the world’s only nocturnal gull, foraging mainly for squid at night, though they also hunt small fish. Their eyes are adapted for night vision. They are significantly larger than those of other gulls, and have a unique tissue layer that reflects light back through the retina, making them particularly sensitive to light.

Tackling Plastic Pollution
"45% of all plastic used along the Pacific coastline of South and Central America is inadequately managed, leaking 1 million tonnes of plastic each year."
We are working with partners across the Eastern Pacific to make Galapagos plastic pollution free once again, identifying the sources and impacts of plastic and supporting innovative solutions.
