Alpine Accentor (Prunella collaris) Science Article 5 abstract Enterococcus strains from highland animals the alpine accentor Prunella collaris (n = 19) and chamois Rupicapra rupicapra (n = 18) were isolated. One third of strains belonged to the species E. casseliflavus, while other were identified as E. faecalis and E. gallinarum, E. faecium and E. mundtii […]

Alpine Accentor (Prunella collaris) Science Article 1 abstract The composition of breeding groups, territoriality, parentage and parental care were examined in a population of Alpine Accentors Prunella collaris in the Swiss Alps. Five (1993) and six (1994) breeding groups were located on a south facing hillside between 2500 and 2860 m above sea level. 3-5 […]

Alpine Accentor (Prunella collaris) Science Article 4 abstract In flocks of Alpine Accentors (Prunella collaris), we observed the foraging behaviour of birds when they were foraging on a grid containing clumps of seeds. We measured the feeding rate, diet diversity, individual and seasonal feeding preferences and dominance in birds. Producing and scrounging were frequently observed […]

Alpine Accentor (Prunella collaris) Science Article 7 abstract Occurrence of bacterial species of the family Enterobacteriaceace and their susceptibility andminimum inhibitory concentrations (MIC90) to 13 selected antimicrobial agents was studied in 22faecal samples of the alpine accentor Prunella collaris. Alpine accentor is our main research avianmodel for the studying of the interaction between the comensal […]

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 […]

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 […]

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. […]

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)
