Individual and temporal variability in the courtship behavior of White- ruffed Manakins (Corapipo altera), a species with facultative cooperative displays

چکیده
Investigation of the ecological and evolutionary basis for the often-intriguing courtship behavior of animals requires that we understand the patterns of variation inherent in such behaviors. The courtship displays of the White-ruffed Manakin (Corapipo altera) are not well-known, and previously published descriptions and interpretations of displays conflict with one another. We studied the reproductive behavior of C. altera during 6 breeding seasons, observing 72 display courts (mean 29 6 2.5 courts annually) for a total of 2688 hr. We updated the behavioral characterization of C. altera by reconciling 8 previous ethologies and describing 2 new behavioral elements, vouchering all with audio and video recordings. We evaluated evidence for the occurrence of male–male cooperation and characterized the physical attributes and temporal dynamics of displays and display courts. We found strong evidence of cooperation among males; 32% of displays for females were highly coordinated displays performed by 2 males, and 8% of those ended in copulation. Males of the highest social status (alphas) retained that status for an average of 1.7 yr (range 1.5 mo to 5 yr). Most alphas remained at a single court during their alpha tenure and rarely declined in social status. Only 23% of second-ranked (beta) males transitioned to alpha status, and of those 70% became alphas at a new display court. Display courts did not seem to be limited because few measured physical attributes differed between active display logs and random logs. Several elements of C. altera display behavior and social organization were more variable than in other manakin species, including high turnover of the display courts. This work provides key information for comparative studies investigating the evolution of cooperation in Pipridae.

Lekking birds in a tropical forest forego sex for migration.
Facultative, partially migratory animals provide a contemporary window into the evolution of migration, offering rare opportunities to examine the life-history trade-offs associated with migration. For the first time, to our knowledge, we describe the nature of these trade-offs, using a lek-breeding tropical bird, the white-ruffed manakin (Corapipo altera). Previous evidence indicated that weat...
متن کاملCooperative Display and Lekking Behavior of the Lance-tailed Manakin (chiroxiphia Lanceolata)
—Male Lance-tailed Manakins (Chiroxiphia lanceolata) perform multimale courtship displays for females. To characterize the behavioral repertoire and the lek spatial organization of this species, I observed lekking males on Isla Boca Brava, Chiriquí Province, Panamá. Breeding began in March and continued through June, though courtship displays were recorded as late as November. Males were active...
متن کاملTestosterone and its effects on courtship in golden-collared manakins (Manacus vitellinus): seasonal, sex, and age differences.
Male golden-collared manakins gather on leks and perform an acrobatic display to attract females. In temperate breeding species, testosterone (T) activation of courtship displays has been well studied. Few studies have examined T activation of displays in tropical species; even fewer have explored the activational role of T in elaborate courtship displays such as in the manakin. In some tropica...
متن کاملEnergetics of the acrobatic courtship in male golden-collared manakins (Manacus vitellinus).
In lek mating systems, females choose mates through indicators of quality, which males may exhibit by their performance of courtship displays. In temperate regions, displaying seasons are brief (one to two months), whereas in the tropics courtship seasons may be prolonged. Moreover, in temperate-breeding animals lekking behaviour can be energetically demanding, but little is known about the ene...
