Observing and Analyzing Behavior

In this lesson, you'll learn the crucial skill of observing and analyzing the behavior of marine mammals. We'll explore how to use ethograms, record behaviors accurately, and identify signs of stress to ensure the well-being of the animals under your care.

Learning Objectives

  • Define and explain the purpose of an ethogram.
  • Identify and describe common marine mammal behaviors.
  • Practice observing and recording behaviors using a simple ethogram.
  • Recognize signs of stress or discomfort in marine mammals.

Introduction to Observation and Animal Behavior

As a marine mammal trainer, your primary job is to understand the animals you work with. This understanding starts with keen observation. Animals communicate through their behaviors, and by paying close attention, you can learn about their needs, preferences, and emotional states. Observing also helps trainers adjust their training methods and provide the best possible care. This allows for a strong trainer-animal bond.

What is an Ethogram?

An ethogram is like a behavior dictionary for a specific animal species. It's a catalog of all the different behaviors an animal might exhibit, along with clear definitions. Think of it like a checklist of behaviors. Using an ethogram helps you standardize your observations and make them more objective and accurate. Here's a simplified example of an ethogram for a dolphin:

  • Surface: The dolphin's body is at the surface of the water.
  • Breach: The dolphin leaps completely out of the water.
  • Spyhop: The dolphin raises its head vertically out of the water.
  • Tail Slap: The dolphin slaps its tail on the water surface.
  • Play Bow: The dolphin lowers its head and raises its tail.
  • Vocalizations: the dolphin is making noises.

Recording Behavior: The Art of Data Collection

Once you have an ethogram, the next step is to record the observed behaviors. This involves taking notes, counting how many times a behavior occurs, and documenting the duration of each behavior. There are different ways to record behavior:

  • Frequency: Counting how many times a behavior occurs within a specific time period (e.g., 5 tail slaps in one minute).
  • Duration: Measuring how long a behavior lasts (e.g., 10 seconds of porpoising).
  • Latency: The time it takes for a behavior to start after a specific event (e.g., the time before a dolphin breaches after a cue).

Analyzing Behavior: Putting the Pieces Together

Analyzing the data you collect allows you to understand patterns in the animal's behavior. For instance, you might notice that the frequency of tail slaps increases when a new person approaches the enclosure, suggesting the animal might be feeling uncomfortable. Analyzing behavior provides critical insight into the animals well-being. By analyzing, it allows for modifications in training and care.

Here are some examples of what you might look for:

  • Changes in behavior: A sudden increase or decrease in specific behaviors.
  • Context: What was happening before, during, and after a behavior? (e.g., training session, feeding time, interaction with other animals)
  • Correlations: Are certain behaviors linked to specific stimuli or events?
  • Identifying Signs of Stress: Observing a wide range of stress indicators helps to ensure the well being of the animals. Be aware of physical indicators as well as behavior changes.

Identifying Signs of Stress and Discomfort

It's crucial to identify signs of stress or discomfort. These can include physical signs and behavioral changes. Here are some examples:

  • Behavioral: Increased aggression, repetitive behaviors (pacing, stereotypies), decreased appetite, avoidance behavior (turning away, hiding), lethargy (reduced activity).
  • Physical: Changes in breathing rate, increased heart rate (which might only be noticeable during a veterinary check-up), changes in skin or color (e.g., blanching or redness around eyes), and changes in vocalizations.
