Experimentally reduced paternity affects paternal effort and reproductive success in pied flycatchers
Article Abstract:
Experimental manipulation of paternal presence in pied flycatchers, Ficedula hypoleuca, was undertaken through mate switching to determine the changes in parental effort relative to reduced paternity. Results reveal that the provisioning efforts undertaken by males declined in the switched broods indicating that males have a reliable indicator of paternity. Further, enhanced paternity behavior is expected in future normal breeding efforts.

Experimental mate switching in pied flycatchers: male copulatory access and fertilization success
Article Abstract:
Sperm competition in birds has caused males to evolve adaptions to ensure that their sperm fertilizes the female's eggs. An experiment with pied flycatchers seeks to discover the success of copulations when the female is fertile. Mate switching, with the subsequent analysis of egg clutches using DNA techniques, was found to markedly influence paternity around the onset of laying.
