Delayed senescence in a southern population of the pied flycatcher (Ficedula hypoleuca)

We determined age-specific changes in survival probabilities and reproductive performance of female pied flycatchers, Ficedula hypoleuca Pallas, breeding in the southern part of the species? breeding range in central Spain. Our aim was to detect evidence of senescence in the course of a long-term st...
