In Daurian Redstarts , personality traits (specifically, whether a bird is shy or bold) partly determine how good an individual is in rejecting cuckoo eggs in its nest. Apparently, birds that are fast in exploring new things – bold birds – are better at rejecting parasitic eggs ( source ).

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.
