This article conducts a cross-cultural, comparative review of whether birds are bearers of signs using eHRAF World Cultures and published articles. The researchers first examine whether birds are thought of as signifiers and the mode of sign delivery be it voice, presence, or behavior. They also investigate whether biocultural salience is more indicative of passerines, near-passerines, or non-passerines.

This article explores determinants of non-classical polyandry, which the authors assert is more common than is usually conveyed. Results indicate that societies with non-classical polyandry tend to be small scale and egalitarian, practice hunting and gathering or horticulture, and have a male-skewed sex ratio. Overall polyandry is thought to add to the reproductive fitness of both men and women.

The association between hunting and sign language is examined. It is hypothesized that sign language develops as a form of nonverbal communication to aid hunters in the coordinated stalking of game. Ethnographic evidence supports this hypothesis. A second hypothesis is also tested concerning the relationship between population size and non-verbal communication, however sampling procedures provided an inadequate test of this hypothesis.

This article examined the presence of ostensive-communicative behaviors in educational storytelling within foraging cultures. Ostensive communication includes prosody and gestures used to direct attention to something or someone. The author analyzed 14 behaviors of ostensive communication and tested whether they co-occur with the transmission of knowledge in storytelling. All 53 forager cultures examined demonstrated the use of 2 or more of those communicative behaviors in oral storytelling. This supports the author’s claim of ostensive-communicative behavior as a universal pedagogical tool in forager cultures.

The present study explores the cognitive and affective attitudes towards owls in cold-climate and warm-climate societies. In addition, a few hypotheses were tested. Specifically, the research question asks which societies would have greater owl ethnozoological knowledge, functional usage, conception of owls in positive magico-religious terms, and positive supernaturalistic interpretations of owls' behaviors and characteristics. The results offer support for the initial predictions with the exception that cold-climate societies do not have more positive magico-religious conceptions of owls than warm-climate societies.

This article examines the association between population size and social organization. Empirical analysis suggests that larger societies tend to develop more elaborate organization if they are to remain unified and integrated.
