A model for the evolution of despotic versus egalitarian societies
TLDR
An optimization model provides insights into the interactions between a basic behavioural process, i.e. dominance, and ecological contexts in determining aspects of population structure such as group size, dispersal pattern, group composition, and fitness bias within groups.
Vocal performance influences male receiver response in the banded wren
TLDR
The results show that male banded wrens discriminate and respond differently to songs based on their vocal performance, which indicates that performance of physically challenging songs may be important in intra- as well as inter-sexual assessment.
Is song–type matching a conventional signal of aggressive intentions?

Song–type matching is a singing strategy found in some oscine songbirds with repertoires of song types and at least partial sharing of song types between males. Males reply to the song of a rival
The energetic cost of display in male sage grouse
TLDR
The energetic expenditure of displaying male sage grouse was measured for 18 individuals in the field using the doubly labelled water technique and neither blood parasites nor the potential effects of other diseases as determined by haematocrit levels were associated with display effort.
Mate choice in lekking sage grouse revisited: the roles of vocal display
TLDR
Analysis of mating distributions from two leks over 4 years that provide evidence for female choice based on differences in vocal display performance of males, the locations at which hens mated in the previous year, and the choices of other females (copying).
Syllable type consistency is related to age, social status and reproductive success in the tropical mockingbird
TLDR
Evidence is presented that tropical mockingbirds decrease the variation between renditions of each syllable type as they grow older and that more consistent males in this species tend to have higher dominance status and reproductive success and it is hypothesized that syllabletype consistency may also be an indicator of the integrity of brain function in birds analogous to the tests used for neuropsychological assessment in humans.
Integrating perspectives on vocal performance and consistency
TLDR
It is argued that genes regulating the function of basal ganglia circuits and sex steroid hormones could be sculpted by sexual selection and gain an appreciation for the various dimensions of song control and plasticity.
Optimal Degree of Skew in Cooperative Societies
Synopsis. An optimization model is employed to determine the outcome of within-group conflict in cooperative societies. The model assumes that selection acts simultaneously on the stronger, dominant
