“…In flocks consisting of three or more pairs, the male submissive to the alpha male but dominant over the low-ranking male was considered mid ranking. We observed too few interactions to determine the rank of six of the 26 birds; in these cases, we used age as a proxy of rank, as rank is strongly associated with relative age (Smith 1991, Otter et al 1999, Ratcliffe et al 2007). …”

“…Thus we determined a linear dominance matrix for each flock, classifying birds as low, mid, or high ranking, according to their position within the flock. Because a female chickadee's rank is correlated with the rank of her social mate (Smith 1991, Otter et al 1999, we concentrated on determining relative rank of males within flocks. In flocks consisting of three or more pairs, the male submissive to the alpha male but dominant over the low-ranking male was considered mid ranking.…”

“…While females have been found to assess relative dominance status of males by 'eavesdropping' on patterns of response (signal conventions) in male-male territorial song contests (Mennill et al, 2002), how this relative quality is conveyed in the apparently 'solo' dawn in April and May is unclear. Otter et al (1997) found dawn chorus start times, durations and song rates could be used discriminate between categories of high-ranking males and their lowest rank ockmates, but efforts to determine if chickadee song structure, per se, can predict this correlate of male quality have been less than conclusive (Chruszcz, 1995;Evans, 1999).…”

“…Birds in ocks demonstrate linear dominance hierarchies that can be discerned by observing interactions at feeders (Ficken et al, 1990). Highranking males in these ocks enjoy better access to food (Ficken et al, 1990), improved survival (Smith, 1991), and better overall reproductive success (Otter et al, 1999) than their low-ranking ockmates. Although pairing appears assortative by social rank, females commonly seek extra-pair copulations with males that rank higher than their social mates do (Otter et al, 1998;Mennill et al, 2002) and divorce their mates for males of higher rank when the circumstances arise (Otter & Ratcliffe, 1996;Ramsay et al, 2000).…”

SummaryThe two-note fee-bee song of male black-capped chickadees functions during the dawn chorus, in part, as a sexual signal across large distances. How song structure might encode information about male quality, however, remains unclear.We studied the availability of cues to male social rank (a proxy indicator of male quality), within the acoustic structure of dawn chorus songs of male chickadees whose ock dominance status we determined the previous winter. We used analysis of variance and discriminant function analysis to demonstrate that ve temporal, frequency or relative amplitude features of song can predict individual identity but not the category of social rank (dominant versus subordinate) to which individuals belong.After transmitting chickadee songs through the forest and re-recording them at four broadcast distances, we found that song structure continued to effectively predict singer identity by our statistical methods despite signi cant acoustic degradation for as long as songs remained audible (up to 80 m).In particular, the relative frequency interval between the two notes is both the most invariant between-male measure and among the most individually distinctive.

“…Dominant males show improved territory acquisition (Desrochers et al 1988) and territory size (Mennill et al 2004). High social status enhances fitness through greater hatching and fledging success of young (Otter et al 1999) and higher rates of genetic paternity (Otter et al 1998, Mennill et al 2004. Dominant males are also preferred as the new mates of females that divorce Ratcliffe 1996, Ramsay et al 2000).…”

Abstract.-In dominance-structured animal societies, variation in individual fitness is often related to social status. Like many passerine birds, Black-capped Chickadees (Poecile atricapillus) have a short average adult life-expectancy (~2 years); however, the maximum recorded life span is >5× as long. Enhanced annual survival could contribute to greater lifetime reproductive success for male Black-capped Chickadees with high social rank. We used multistate capture-mark-recapture models to estimate annual survival of male Black-capped Chickadees in Ontario using resighting and recapture data collected from 1997 to 2002. Our goal was to evaluate support for an influence of rank on annual survival and estimate its effect size for a food-supplemented study site. We also statistically modeled the probability of between-year rank transitions. Model selection based on Akaike's information criterion provided support for an effect of rank on survival. However, multimodel inference revealed that the size of the effect was rather small. Over the six study years, model-averaged estimates of the survival benefit of high versus low rank ranged from 5.0 to 7.3%. As expected, survival was strongly year-dependent, with model-averaged estimates of annual survival probability varying between 0.36 and 0.73. Age was an important predictor of the probability of rank transitions. Low-ranked second-year birds were less likely than older low-ranked birds to advance to high rank between years; likewise, high-ranked after-second-year birds were less likely to drop in rank. Other studies have found larger effects of rank on survival than we observed here. Future research should consider how interactions between social and environmental factors influence annual survival.

Survie interannuelle et transitions de rang chez les Poecile atricapillus mâles : une méthodologie de modélisation à états multiplesRésumé.-Dans les sociétés animales structurées sur la dominance, la variation du fitness individuel est souvent liée au statut social. Comme plusieurs passereaux, Poecile atricapillus a une courte espérance de vie adulte moyenne (~2 ans). Toutefois, la durée de vie maximale enregistrée est >5× plus longue. Une survie annuelle accrue pourrait contribuer à un succès reproducteur à vie supérieur pour les mâles de haut rang social. Nous avons utilisé des modèles de capture-marquage-recapture à états multiples afin d'estimer la survie annuelle de P. atricapillus mâles en Ontario en utilisant des données de ré-observation et de recapture récoltées entre 1997 et 2002. Notre objectif était d'évaluer l'influence du rang sur la survie annuelle et d'estimer la taille d'effet sur un site d'étude de nourrissage. Nous avons aussi modelé statistiquement la probabilité des transitions de rang entre les années. La sélection des modèles basée sur le critère d'information d'Akaike a supporté l'hypothèse d'un...
