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.
