Clearly, the problem with this method is that observations will be biased towards those behaviour patterns and individuals which happen to be most conspicuous. AD LIBITUM SAMPLING In field studies of behavior, perhaps the most common form of behavior record consists of what I shall call "typical field notes", or "Ad Lib. Sam- pling." Of course, the same type of record can be obtained in the laboratory by means of non-systematic sampling or informal observations. Sampling Rules Ad libitum - This sampling method is used to record what you want, however this method is not very useful for Focal - In this sampling method only the behavior of one animal or group of animals is recorded. Scan - This method scans a group of animals and the behavior of each is servations, or what I have called ad libitum sampling, and the findings were, consequently, subject to the biases caused by attention-attracting, dramatic events, by the individual biases of each observer, and so on. For reliable and valid results, however, we must turn to more systematic techniques.

Ad libitum sampling is a good way to decide what behaviors are important to focus on without biasing your observation based on preconceiv ed assumptions. However, it’s not great for quantitative data collection (e.g., frequency that something happens).
This is a good method for initial observations and question formation for later research, but is limited in the quantity and quality of data produced.

There are several ways to sample when making observations. Non systematic ad libitum sampling is where the observer records whatever is of interest. Focal sampling involves recording all the behaviours and physical features over a designated period of time. DISCUSSION Ad Libitum and Focal-animal Sampling Ad libitum scoring is much maligned but still very common. It is often used as a compromise when time pressures under difficult conditions preclude the investment required in focal-animal sampling.

A good way to decide what behaviors are important for the animal you are studying. As a direction in sheet music, ad libitum indicates that the performer or conductor has one of a variety of types of discretion with respect to a given passage: to play the passage in free time rather than in strict or " metronomic " tempo (a practice known as rubato when not expressly indicated by the composer); Ad libitum sampling: writing down anything that seems interesting or important about one animal or a group of animals over a period of time. Focal sampling: watching one animal for a set length of time and writing down everything the animal does with the time noted. Ad libitum Sampling means recording any behavior of any individuals that appears relevant to the observer. It is often used during the initial phase of descriptive studies and during reconnaissance observations (Lehner, 1979) when formulating and fine-tuning research questions. 1 Ad libitum sampling means that no systematic constraints are placed on what is recorded or when. The observer simply notes down whatever is visible and seems relevant at the time.
