“…The discovery of specializations of both male motor control circuitry and female visual processing centres [Day et al, 2011] supports the idea that the manakin brain has been shaped by evolution to support both male performance and female assessment of courtship display [Day et al, 2011]. Enhanced spatial cognition may also be necessary for both choreographed use of the spatial structure within a display arena [Coccon et al, 2012;Fusani et al, 2007b] and spatial navigation between alternate arenas [Prum, 1986;Rosselli et al, 2002;Théry, 1990]. Removal of a single perch in a golden-collared manakin's display arena reduces display quality [Coccon et al, 2012] and in whitethroated (Corapipo gutturalis) and white-ruffed manakins (C. altera), males can display on multiple arenas separated by upwards of 350 m [Prum, 1986;Rosselli et al, 2002;Théry, 1990].…”

“…In golden-collared manakins (Manacus vitellinus), females choose mates based on millisecond differences in the performance of postural display sequences [Barske et al, 2011], and males vary in terms of the timing of these display elements [Fusani et al, 2007b]. The discovery of specializations of both male motor control circuitry and female visual processing centres [Day et al, 2011] supports the idea that the manakin brain has been shaped by evolution to support both male performance and female assessment of courtship display [Day et al, 2011].…”

Acrobatic display behaviour is sexually selected in manakins (Pipridae) and can place high demands on many neural systems. Manakin displays vary across species in terms of behavioural complexity, differing in number of unique motor elements, production of mechanical sounds, cooperation between displaying males, and construction of the display site. Historically, research emphasis has been placed on neurological specializations for vocal aspects of courtship, and less is known about the control of physical, non-vocal displays. By examining brain evolution in relation to extreme acrobatic feats such as manakin displays, we can vastly expand our knowledge of how sexual selection acts on motor behaviour. We tested the hypothesis that sexual selection for complex motor displays has selected for larger brains across the Pipridae. We found that display complexity positively predicts relative brain weight (adjusted for body size) after controlling for phylogeny in 12 manakin species and a closely related flycatcher. This evidence suggests that brain size has evolved in response to sexual selection to facilitate aspects of display such as motor, sensorimotor, perceptual, and cognitive abilities. We show, for the first time, that sexual selection for acrobatic motor behaviour can drive brain size evolution in avian species and, in particular, a family of suboscine birds.

Understanding testosterone variation in a tropical lek-breeding bird

2011

Male reproductive coalitions, in which males cooperate to attract females, are a rare strategy among vertebrates. While some studies have investigated ultimate aspects of these relationships, little is known about the mechanistic role that hormones play in modulating cooperative behaviours. Here, we examined male testosterone variation in a tropical lekking bird, the wire-tailed manakin (Pipra filicauda), which exhibits cooperative male -male display coalitions. We found that testosterone levels in territorial males were comparable to those of temperate breeding birds, a surprising result given their environmental, social and reproductive dynamics. In addition, social status rather than plumage was a strong predictor of testosterone variation. Territorial males had significantly higher testosterone levels than did two other plumage classes of floater males, who do not hold territories. We hypothesize that testosterone variation plays an important role in the establishment of male dominance hierarchies (competition), while concurrently facilitating stable display partnerships (cooperation).

“…For example, it has been reported that plasma testosterone levels correlate with testes size (Denk and Kempenaers 2005;Garamszegi et al 2005), ornament size or color (Buchanan et al 2001;Redpath et al 2006), territorial and aggressive behavior, including mate guarding (Soma 2006), singing behavior (De Ridder et al 2000;Foerster et al 2002), courtship behavior (Fusani et al 2007), and mating success (Raouf et al 1997;Redpath et al 2006;Kempenaers et al 2008) in birds. Similar observations have also been made in mammals and humans (Beehner et al 2006;Mazur 2006;Wingfield et al 2006;Scotti et al 2008;Chichinadze et al 2009Chichinadze et al , 2010Chichinadze et al , 2011.…”

Testosterone dynamics during encounter: role of emotional factors

et al. 2012

This study attempts to develop a new theory to explain the varying dynamics of testosterone levels in dominant (winners) and subordinate (losers) males, both pre- and post-encounter. The crux of our new theory consists of the following four theses: (1) the strengthening of testosterone synthesis is a result of not only the existence of challenges, but also of a positive mood before an encounter that is associated with the anticipation of a victory; (2) in situations where the anticipation of victory is present but the positive mood is absent, no rise in testosterone levels will occur; (3) testosterone acts as a "pleasure" hormone and usually releases in situations where the individual achieves or anticipates possible satisfaction; (4) an increased release of testosterone to the blood not only decreases anxiety but also elevates the mood, which increases animal's/human's assertiveness and consequently aggressiveness.
