Kopulationen und Partnerbewachung beim NeuntöterLanius collurio

Copulations and mate-guarding in the Red-Backed Shrike (Lanius collurio)

Abstract

Frequent copulations in Red-backed Shrikes can be explained best by the sperm-competition hypothesis. Mate-guarding serves to prevent EPC and may reduce predation risk. Courtship-feeding at the female's arrival promotes the pair-bond and facilitates mate-guarding and copulations in the fertile period.
