Introduction Monitoring behavior in animals and humans can be done in many different ways. Several different methods exist for observation of primates. Four specific methods were introduced in class: Ad libitum sampling, Focal Animal Instantaneous sampling, One-Zero sampling, and Scan sampling. Ad libitum sampling is when observers writes down anything that is of interest that happens, noting when it occurred and what happened. Focal Animal Instantaneous sampling is a method where an observer uses a chart, and records certain aspects about an animal's behavior on a timed schedule.One-Zero sampling gives a score for each behavior that is related to budget, duration, and frequency. Scan sampling looks at the behavior of all individuals in a group, which is recorded at certain time intervals. I spent a total of four hours monitoring the behavior of a female gorilla at the Omaha zoo, and chose to use Ad libitum sampling and Focal Animal Instantaneous sampling. After using both methods I found that each served a slightly different purpose, and gave different ways for it to be analyzed. This led me to ask: which method was better? Though these methods are different each has its respective uses. Materials and Methods The species I observed was a Western gorilla, whose scientific name is Gorilla gorilla. The specific gorilla I observed was a 12 year old female named Bambio. Who was born at the Henry Doorly Zoo on August 16, 2003. There were only two gorillas in this enclosure that that was…show more content…
Ad libitum sampling is when observers writes down anything that is of interest that happens, noting when it occurred and what happened. This method tends to be less organized, and looks to record as much as possible. While Focal Animal Instantaneous sampling is a method where an observer uses a chart, and records certain aspects about an animal's behavior on a timed
