摘要: Sexual selection theory suggests that the degree of protandry in spring migration should increase when earlier males benefit from better mating opportunities. Western European studies failed to show differences sex-specific arrival dates for Pied Flycatcher. However, different climatic conditions and other constraints may affect its phenology continental Europe. Here, we present evidence sex-related phenological changes have occurred over past 25 years (between 1989 2013) Central Europe (Ocsa Bird Ringing Station, Hungary). The male flycatchers shifted whereas female showed no change, implying an increasing protandry.
