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 […]
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 […]
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 […]
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)
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. […]

The probable Breeding of the Aleutian Tern in Southeastern Alaska
Aleutian Tern (Onychoprion aleuticus) Science Article 2 abstract A record in the May, 1920, number of THE CONDOR (page 111) of the probable breedingof the Aleutian Tern near Yakutat appears to rest on ‘sight’ identification only, andthe actions of Mr. Walker’s birds were so different from the usual habits of this speciesthat 1 am forced […]
Possible Winter Quarters of the Aleutian Tern?
Aleutian Tern (Onychoprion aleuticus) Science Article 3 abstract Recent observations of the Aleutian Tern (Sterna aleutica) in the coastal waters aroundHong Kong in spring and fall, and Singapore and the Indonesian islands of Karimun and Bintan between October and April indicate that at least part of the population of this species migrates through and winters […]

Aleutian Tern (Onychoprion aleuticus) Science Article 1 abstract Two dead aleutian Ternsms wee found dead along river otter trailsin a a colony. Although literature suggests the otter is commonly predating on colonies, the colonies prevail. D. C. Duffy, Colonial Waterbirds 18(1): 91-92, 1995 Download article download full text (pdf)
