What is the use of an ethogram in animal behavior studies?

• A. Systematically records and categorizes behavior to assess welfare and management needs
• B. Measures body weight
• C. Detects parasites
• D. Tracks breeding cycles

Answer: (A)

An ethogram is a structured catalog of defined behaviors used to observe and record what animals do in a systematic way. By watching animals and coding each behavior into these predefined categories, researchers can build objective data on how much time is spent on different activities, how often behaviors occur, and in what sequences they appear. This time-budget information and the ability to compare behaviors across individuals, groups, or over time makes it possible to assess welfare and inform management decisions. For example, increases in abnormal or repetitive behaviors can signal stress, poor enrichment, or housing issues, while improvements in the variety and duration of normal activities often reflect better welfare.

While measuring body weight, detecting parasites, or tracking breeding cycles are important tasks, they rely on other tools and records, not the behavioral cataloging that an ethogram provides.
