“…Drumming is a relatively simple motor display: It is a single repeated element. In contrast, other bird species incorporate a diverse range of movements into their displays (Fusani et al, ; Fuxjager et al, ; Hjorth, ; Johnsgard, ; Manica et al, , ; Ribeiro, Guaraldo, Macedo, & Manica, ). Each one of the elements used in these complex courtship displays might also vary throughout the day and with each performance, but studies comparable to ours have yet to be conducted in other avian species.…”

Courtship displays are typically comprised of the same behavioral pattern, or patterns, repeated several times by males. Both the quantity and quality of the displays produced by a given male bird are not, however, constant. The number and/or quality of displays can decrease over time, indicating fatigue, or males can increase the number and/or quality as they display more, indicating a warm‐up period. Although there is evidence for fatigue or warm‐up periods for many types of courtship displays, data on motor components of avian courtship are scant, despite how commonly they are used. Here, we test whether drumming, a non‐vocal motor display, in male ruffed grouse (Bonasa umbellus) changes in relation to the number of displays executed. Using a large number of recordings, our linear mixed models yielded a significant effect of cumulative number of drumming displays on the number of wingbeats per second, referred to as pulse rate. Across males, pulse rate is slowest when males begin drumming each day and increases until approximately 50 drumming displays have been produced. The rate of increase is also modulated by the nighttime low temperature such that cooler conditions are associated with lower pulse rates and a slower increase in pulse rate relative to the cumulative number of displays. Further, the maximum pulse rate recorded and average pulse rate after 50 displays is inversely correlated with body mass such that larger males are slower than smaller males. We suggest that the daily changes in pulse rate likely reflect a warm‐up period based upon the effects of cumulative drumming count and temperature on pulse rate. Whether these dynamic changes in the production of a motor display are informative to female grouse is unknown. However, we propose that daily changes in how motor displays are performed may be a common feature of avian courtship that has gone relatively unnoticed, despite the potential for motor performance to be a trait that is important for female mate choice.

“…For instance, in swallow-tailed manakins (Chiroxiphia caudata), the so-called practice displays (i.e. courtship bouts performed by subordinate males) have been shown to differ from those of mature males (Ribeiro et al 2019;Schaedler et al 2021).…”

Despite strong selective pressures inherent in competition for mates, in species with non-resource-based mating systems males commonly engage in non-agonistic interactions with same-sex visitors at display arenas. Bowerbirds perform courtship dances on elaborate display structures — known as bowers — that are built and defended by one resident male. Several reports have suggested that bower owners tolerate the presence of specific male visitors at their display arenas, referred to here as ‘subordinates’. Subordinate males may learn the skills required for successful sexual signalling via prolonged social interactions at adults’ arenas, but little is known about whether courtship proficiency changes with experience and/or whether subordinates actively contribute to enhancing the resident male’s mating success. In this study, we investigated male-male associations in wild spotted bowerbirds (Ptilonorhynchus maculatus). We first sought to determine whether courtship behaviour differs based on bower ownership status. We then examined whether social interactions between bower owners and subordinate males may qualify as courtship coalitions. Our analysis of courtship postural components did not reveal differences in timing or relative occurrence of postural components between subordinate males and bower owners, whereas we found evidence that male-male associations in spotted bowerbirds may provide an example of rudimentary courtship coalitions. In particular, higher subordinate attendance is associated with lower destruction rates by neighbouring rivals and with overall higher mating success, and male pairs are stable in subsequent years. This study provides novel information about social dynamics among male bowerbirds, and further insights into the evolution of coalitionary behaviour in male displays. Significance statement Same-sex associations between established males and subordinate visitors on display arenas are common in birds, yet poorly understood. Using video recordings from a population of wild spotted bowerbirds, Ptilonorhynchus maculatus, we performed a quantitative analysis on motor courtship components across males, and on their social interactions on display arenas to investigate the nature of male–male partnerships. Our results showed that motor courtship performance in subordinate visitors is not suggestive of an early ontogenetic stage, as previously speculated. Moreover, though bower ‘owners’ and subordinate males do not coordinate their behaviour during courtship or bower building, male–male partnerships may qualify as a rudimentary or incipient form of courtship coalitions. Subordinate males are tolerated at bowers, the magnitude of subordinate attendance correlates with owner males’ mating success, and repeated interactions between individuals reveal consistent partner associations.

“…Manakins (Pipridae) are commonly found in the understory of Neotropical forests (Loiselle et al 2007, Kirwan and Green 2011, Winkler et al 2020). These small frugivorous birds are characterized by intense sexual dimorphism, and complex pre-nuptial displays (Duval 2007, Francisco et al 2009, Foster 1981, 1985, Loiselle et al 2007, McDonald 1989, Ribeiro et al 2019, Winkler et al 2020. While males are bright colored, females are generally green.…”
