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.

Extended Learning: Marine Mammal Trainer - Animal Behavior & Psychology (Day 5)
Welcome back! You've learned the fundamentals of observing and analyzing marine mammal behavior. Today, we'll delve deeper into the nuances of these critical skills, expanding your knowledge and equipping you with practical tools to become a more effective trainer and caregiver.
Deep Dive Section: Beyond the Basics - Understanding Context and Individual Differences
While ethograms provide a structured framework, remember that animal behavior is complex and context-dependent. A behavior's meaning can change based on the environment, the individual animal, and its social dynamics. Consider these key points:
- Environmental Context: Is the animal in a training session, a resting area, or interacting with enrichment? How does the weather or water conditions affect its behavior? For example, a "fast swim" might be play in a normal environment but a stress response if the animal is escaping a perceived threat.
- Individual Differences: Each marine mammal has a unique personality and behavioral history. What is considered "normal" can vary. One dolphin might be naturally more playful than another. Long-term observation is crucial to understanding an individual animal's baseline behavior.
- Social Dynamics: Marine mammals are often social creatures. How the animal interacts with others in its group (pods or pairings) provides significant behavioral clues. Observe how animals communicate, share resources, and navigate social hierarchies.
- The Importance of Documentation: Go beyond just recording the behavior. Note the antecedents (what happened before the behavior) and the consequences (what happened after the behavior). This helps you understand the triggers and functions of the behavior.
Bonus Exercises
Exercise 1: Ethogram Design Challenge: Create a simplified ethogram for observing a specific behavior, such as "surface resting" in dolphins or "vocalizations" in sea lions. Include at least 5 distinct categories within your chosen behavior (e.g., for surface resting: "float still," "breathe and reposition," "eye open," "eye closed," "spyhop").
Exercise 2: Case Study Analysis: Research a published case study on marine mammal behavior (scientific journals, reputable websites of marine mammal facilities). Identify the ethogram or observation methods used, the key findings, and what you learned from the study about interpreting the animal's behavior.
Exercise 3: Behavior Interpretation Scenario: Imagine you observe a sea otter repeatedly scratching its head after a training session. Based on your knowledge of behavior and the context, what are three possible explanations for this behavior? How would you gather more information to determine the most likely cause (e.g., is it a stress signal, a sign of irritation, or a simple grooming behavior)?
Real-World Connections
Understanding animal behavior is vital in many aspects of marine mammal care and training:
- Training Effectiveness: Knowing how an animal learns and what motivates it allows you to design more effective training programs. This includes using positive reinforcement, shaping behavior, and understanding the role of environmental enrichment.
- Animal Welfare: Early identification of stress or illness allows for prompt intervention. This minimizes suffering and improves the overall well-being of the animal.
- Research and Conservation: Behavioral data helps researchers study marine mammal populations in the wild, understand threats they face (e.g., pollution, habitat loss), and develop conservation strategies.
- Public Education: Trainers often play a role in educating the public about marine mammal behavior and conservation efforts, inspiring empathy and awareness.
Challenge Yourself
Challenge: Shadow a senior trainer or experienced observer at a marine mammal facility (if possible). Observe a training session and try to anticipate the animal's responses to different training cues. Afterward, discuss your observations with the trainer. Focus on the correlation between training methodology and animal behaviour.
Further Learning
Explore these topics to further your understanding:
- Applied Behavior Analysis (ABA): A science that applies behavioral principles to improve socially significant behaviors. Many training techniques are based on ABA principles.
- Cognitive Ethology: The study of animal cognition, including learning, memory, and problem-solving.
- Marine Mammal Communication: Research different types of communication (vocalizations, body language, social cues) across different marine mammal species.
- Animal Welfare Legislation and Ethics: Understand laws and ethical considerations related to the care and welfare of marine mammals.
- Research papers: Look for publications in scientific journals, such as "Marine Mammal Science" or "Animal Behaviour".
Interactive Exercises
Ethogram Creation
Imagine you are observing a seal. Using the provided list of common behaviors, create a basic ethogram: * **Surface** (Body is at the surface) * **Swim** (Moving through the water) * **Porpoise** (Breaching frequently) * **Rest** (Lying still at the surface or on land) * **Vocalization** (Making sounds) Define each behavior using short, clear phrases. Write down the definition for each behavior
Observation Practice
Watch a short video of a marine mammal (a dolphin would be ideal) for 1 minute. Using the ethogram you created, record how many times you observe each behavior. You can use tally marks or a simple spreadsheet. If you do not have video, simply imagine you have a marine mammal in front of you.
Behavioral Analysis Scenario
Imagine you observe a dolphin engaging in repetitive pacing behavior along the edge of its enclosure. What factors might you consider to analyze this behavior? What questions would you ask yourself to understand the possible causes (e.g. food availability, recent training, new animals in the area)?
Stress Signal Identification
Think of what stress signs could be exhibited by an Orca and describe them.
Practical Application
Imagine you are working at a marine park. You notice that a beluga whale is spending a lot of time near the surface of the water, and you also notice she has decreased appetite. Create a simple ethogram with three key behaviors and observe the whale for 30 minutes, recording the frequency and duration of each behavior. Based on your observations, what conclusions can you draw, and what steps would you take?
