The Andean gull (Chroicocephalus serranus) can be found in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. They typically measure 42-48 cm (17-19 in) in length. They have a black head with a white crescent behind the eye, white tail, white body, and grey back. Sometimes they have a pink flush on the underparts. The underside of the wing is pale gray with a black outer half and large white "mirrors" on the three outermost primaries. They have brown eyes and dark reddish brown legs and bill. They feed on worms, insects, amphibians, small fish, and occasionally eggs and chicks of waterbirds in the mountains; and offal, fish, and marine invertebrates along the coast.

The lava gull (Leucophaeus fuliginosus) is the rarest gull in the world. They are found only on the Galápagos Islands, predominantly the Santa Cruz, Isabela, San Cristobal, and Genovesa islands, with an estimated population of 300-600 individuals. They typically measure 51-55 cm (20-22 in) in length. Unlike other hooded gulls, their sooty brown-to-black head does not vary by season. They have red eyelids and white eye crescents. Their body is dark grey with paler grey underparts, their bill and legs are black, and their wings are dark grey with a white leading edge. On Genovesa they exploit the kleptoparasitic behavior of the magnificent frigatebird, capitalizing on botched attempts by the frigatebirds to steal fish from other seabirds. Unlike most gulls which nest close together, they are solitary nesters. They are listed as vulnerable by the IUCN.

They have a varied diet that includes earthworms, insects, amphibians, and small fish. Breeding mostly between July and August, they nest in small colonies. Unlike most closely related gull species, they breed in mountainous areas.
