Territoriality and song as flexible paternityguards in dunnocks and alpine accentors

Alpine Accentor (Prunella collaris) Science Article 6 abstract I compare paternity defense strategies in the variable mating systems of alpine accentors Prunella collaris and dunnocks P. modularis. I show that in dunnocks breeding territoriality functions exclusively for mate defense Naomi E. Langmore, Behavioral Ecology Vol. 7 No. 2: 183-188 Download article download full text (pdf)

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 […]

EVOLUTIONARY ASPECTS OF PARENTAL BEHAVIOR:DISTRACTION BEHAVIOR OF THE ALPINE ACCENTOR

Alpine Accentor (Prunella collaris) Science Article 8 abstract Most animals that demonstrate parental care also engage in behavior thatincreases their offsprings’ chances of survival when confronted by a predator,often at the risk of injury or death to the parent itself. Such ‘altruistic’parental behavior ranges from concealment and immobility to outright attacksupon the predator. DAVID P. […]
