Time-Budgets of Camargue Horses Iii. Environmental Influences1. Time-budgets of female, male and yearling horses were calculated for 34 weeks over two years. There was little variation in the time spent in different activities during autumn and winter (Aug.-Mar.). 2. The horses spent more time lying (sleeping) in spring, when on a high protein diet. In summer they spent more time standing alert and walking, less feeding, probably because of the atta... ...

Semantics of an Avian Alarm Call System: the Male Domestic Fowl, Gallus DomesticusAbstract Vocal alarm signals of male domestic fowl given in the presence of predators and other ground and aerial objects were recorded and analyzed. Studies were conducted under semi-naturalistic conditions and a telemetric technique was used to facilitate high quality sound recording. Cockerels gave ground alarm calls specifically to objects moving on th...

When sounds collide: the effect of anthropogenic noise on a breeding assemblage of frogs in Belize, Central AmericaAbstract Many organisms depend on acoustic communication for myriad functions, and have evolved behaviours to minimize effects of naturally occurring acoustic interference. However, as habitats are subject to increased alteration, anthropogenic noise becomes unavoidable, and how animals overcome such interference is not well understood. In most ecosystems,...

Communication During Monocular and Binocular Looking in European Jays ( Garr Ul Us G. Glandarius)
Abstract
Some aspects of communication during monocular and binocular looking by dominant jays at subordinate cage mates were studied. The probability that each type of looking was followed by attack in the sender was measured in standardized external situations. The signal value of the various signal situations for recipients was measured by d... ...

The Responsiveness of Newly Born Clun Forest Lambs To Odour Sources in the Ewe
Abstract
Two groups of newly born lambs, twelve ("suckled" lambs) having been fed by the mother and aged between 3 and 21 h, and twelve ("unsuckled" lambs) taken at birth with minimal olfactory experience of the dam, were tested with the smell of three substances taken from the mother and three taken from an alien ewe. The substances were ingui... ...

A Comparison of the Social Postures of Some Common Laboratory Rodents
Abstract
This paper describes elements in the social behaviour of the laboratory rat, mouse, hamster and Guinea-pig. These elements are divided into postures, which are static, and acts, which involve movement. A total of 45 of these elements are mentioned, most of which are common, with only slight modification, to all four species. Apart from... ...

THE EFFECT OF THE SEX OF AN AUDIENCE ON MALE-MALE DISPLAYS OF SIAMESE FIGHTING FISH (BETTA SPLENDENS)Abstract Communication in the natural environment often involves more than a simple sender-receiver dyad because signals may be detected by more than one individual (i.e. communication occurs in networks). The presence of individuals other than those involved in the signalling interaction has been shown to change signallers' behaviour. Previous experiments...
