Nests in rock
crevices; incubating bird

on soft damp soil on floor
of rock crevice, or on collections
of small pebbles and detritus
in a rock crack; perhaps
occasionally on bare rock.
Egg normally laid in a shallow
depression on floor of crevice,
apparently excavated by bird
where possible. |

distinctive, pungent, citrus-like
odor. In the Americas,
they breed on remote islands
in the Bering Sea, Pribilof
islands, and the Aleutians.
Outside the Americas, they
breed on central Kurile Islands.
