Extra‐pair paternity ( EPP ), where offspring are sired by a male other than the social male,
varies enormously both within and among species. Trying to explain this variation has proved …

Demographic processes play a key role in shaping the patterns of social relations among
individuals in a population. Social network analysis is a powerful quantitative tool for assessing …

Although heterospecific associations beneficial to one or both species involved (eg
commensalisms or mutualisms) are common, it is generally assumed that interactions between …

Sexual dichromatism in birds is often attributed to selection for elaboration in males. However,
evolutionary changes in either sex can result in plumage differences between them, and …

Advances in data‐logging technologies have provided a way to monitor the movement of
individual animals at unprecedented spatial and temporal scales. When used in conjunction …

Historically, bird song complexity was thought to evolve primarily through sexual selection on
males; yet, in many species, both sexes sing and selection pressure on both sexes may be …

Behavioral shifts can initiate morphological evolution by pushing lineages into new adaptive
zones. This has primarily been examined in ecological behaviors, such as foraging, but …

Buggy Creek virus (BCRV) is an unusual arbovirus within the western equine encephalitis
complex of alphaviruses. Associated with cimicid swallow bugs (Oeciacus vicarius) as its …

Avian mixed-species flocks are ubiquitous across habitats and a model for studying how
heterospecific sociality influences the behavior and composition of animal communities. Here, …

Cooperative breeding, in which auxiliary group members help rear related, but nondescendent
young, is often explained by kin selection. Reproductive monogamy is predicted in …
