A few families have a small number of eggs in the clutches, like gulls or cormorants. Others, like the petrels and some of the auks, will lay a single egg per breeding attempt. Others invest much more effort into fewer young, giving a smaller number a much better start. Seabirds are one group of birds that go for the latter strategy.

In this system, females mate and lay eggs with multiple males over the course of a breeding season, leaving males to incubate the eggs and raise the chicks. A single female often lays a clutch of eggs sired by multiple males, and multiple males will in turn help care for the chicks once they hatch (Briskie 1992, 2009, Briskie et al.
