Vigilance behavior in animals has been attributed to various scientific explanations. One of the nearly widely accepted functions of alerting is to increase the ability to chance upon predators. This skill is better known as anti-predator vigilance. Anti-predator vigilance is draw simply as a state of being alert to predators. This is an imperative ability for almost any animals survival. Animals, as sanitary as humans, need to constantly be aware of the dangers environ them. In revisal to stay safe from predators or different threats, animals often find safety in mathematical groups and exhibit vigilance within these groups. This may include a herd of buffalo periodically raising their items in search of wolves, or a woman walking down the street checking both shipway for cars. In an attempt to describe the functions of vigilance we have chosen to study two seemingly important facets: Group sizing and position.
One vital aspect of vigilance is group surface. Bertram (1980) demonstrated this descent in a study of vigilance and group size in ostriches (Struthio camelus). The purpose of the study was to investigate and predict the cogitate behind vigilance. Bertram operationally defines vigilance in ostriches as all(prenominal) time an individual raised or lowered its head. The nonsymbiotic unsettled of his study was group size and included terce different levels.
These levels were one, two, and three or more birds. The dependent variable was vigilance rate. This was not a true experiment callable to lack of manipulation, rather, Bertram conducted a systematic observational study. Bertram counted the number of times each individual raised or lowered its head, as well as, the length of time the bird kept its head raised. Bertram discovered that less vigilance occurred amongst ostriches within the larger groups. It fecal matter be concluded from the data that an increase in group size gives...
