AbstractBehavioral interactions among color‐marked individualVidua chalybeatathat shared common song dialects were observed for 5 years in two populations at Lochinvar National Park, Zambia. Social interactions involved ♂♂ visiting and competing for mating sites and ♀♀ visiting ♂♂ in an apparent sampling of potential copulating partners. Differences in mating success among the polygynous ♂♂ were compared with male behavior and territory resources, and criteria were developed to test the importance of intrasexual male competition and female mate choice in explaining the mating system of the populations. Song behavior best explained differences in mating success of ♂♂ with lesser effects of neighboring ♂♂ and the defensible resources around the call‐sites. The social organization of song populations resembles that of a dispersed lek with ♀♀ visiting many ♂♂ but mating with few ♂♂. We discuss the observations on indigobirds in relation to behavioral selection, sexual selection, and mating systems. Mating systems of certain populations and species are compared using

摘要:

AbstractBetween the siblings of a family of greylag geese (Anser anserL.) a rank order is established by fighting during the first days after hatching, and also by other, more complex interactions. The position of each goose in the rank order can be defined by three groups of behaviour patterns (aggressive behaviour, “greetings”, escape responses). A clear‐cut ranking relation between two individuals is a prerequisite for their close cohesion. The survival function of rank order lies in diminishing the intensity and frequency of agonistic interactions, in diminishing social stress situations and in guaranteeing the close family coh

摘要:

AbstractPlay behavior was studied in a captive group of Siberian ibex at the Chicago Zoological Park. The hypothesis that physical training effects were at least partially responsible for the evolution of play in this species was tested by noting the amounts of play which occurred on flat and on sloped surfaces. The kids showed a clear preference for play on sloped terrain, even though this choice resulted in considerably greater risks. The danger involved in highly active locomotor play performed on steeply sloped areas is presumably outweighed by the physical training benefit for an adult life spent moving in precipitous areas.

摘要:

AbstractWild‐coloured Zebra Finch nestlings with fully developed mouth markings were compared with white mutants, which lack the markings, with respect to the ability of these markings to release the feeding response of both wild‐coloured and white parents. In more than 80 nestlings, the wild‐coloured ones proved to have a higher survival rate, to grow faster, to be given more food, and to have priority to the first feedings in the day. Within the colour groups greater relative age was as advantageous as mouth markings were between g
