Multiple mating opportunities boost protandry in a pied flycatcher population

Protandry, the earlier arrival of males than females to breeding areas, is widespread in birds, but its underlying mechanisms are far from well understood. The two, not mutually exclusive most highly supported hypoth- eses to explain avian protandry postulate that it has evolved from intrasexual mal...

The two, not mutually exclusive most highly supported hypoth- eses to explain avian protandry postulate that it has evolved from intrasexual male competition to acquire the best territories (“rank advantage” hypothesis) and/or to maxi- mize the number of mates (“mate opportunity” hypothesis). We studied for two consecutive years the relative impor- tance of both hypotheses in a population of pied flycatchers (Ficedula hypoleuca), a territorial songbird with a mixed mating strategy.
