Female control of copulations to maximize male help: a comparison ofpolygynandrous alpine accentors, Prunella collaris, and dunnocks,P. modularis
Alpine Accentor (Prunella collaris) Science Article 3 abstract Alpine accentors and dunnocks bred in polygynandrous groups in which two or moreunrelated males shared two or more females. In both species, a female solicited actively to both alphaand subordinate males whereas an alpha male attempted to guard the female to monopolize paternity.Females combated the restrictions imposed […]
Cloacal protuberance and copulatory behavior of the Alpine Accentor (Prunella collaris)
Alpine Accentor (Prunella collaris) Science Article 2 abstract I studied the cloacal protuberance and copulatory behavior of the Alpine Accentor (Prunella collaris) over three breeding seasons in central Japan. In males, the seasonal hypertrophy of the glomus seminales forced the posterior wall of the cloaca to form a bulbous cloacal protuberance (16 mm maximum observed […]
