Listening to Whales

1. A Lifelong Passion for Marine Life Leads to Orca Research

There was so much to learn, so many mistakes to be made.

Early fascination with nature: Alexandra Morton's journey into orca research began with a childhood love for all things slippery, furry, scaled, and feathery. Growing up in Lakeville, Connecticut, she was drawn to the local ponds and forests, developing a particular interest in reptiles and amphibians.

Inspiration and education: Influenced by Jane Goodall's work with chimpanzees, Morton pursued her passion for animal behavior. She gained experience working with John Lilly on dolphin communication and at Marineland studying captive orcas. These experiences laid the foundation for her future field research with wild killer whales.

Transition to field research: Morton's desire to study orcas in their natural habitat led her to the waters of British Columbia. She settled in the Broughton Archipelago, where she could observe and record the behavior of wild killer whale populations, marking the beginning of her lifelong dedication to understanding these magnificent creatures.

2. The Complex Social Structure and Intelligence of Killer Whales

To study a wild animal, you must adapt your life to its rhythm.

Matrilineal society: Killer whales live in highly structured family groups called pods, led by matriarchs. These pods are composed of multiple generations of related females and their offspring, with males staying with their mothers throughout their lives.

Communication and culture: Orcas have sophisticated communication systems, using a variety of calls, whistles, and clicks. Each pod has its own distinct dialect, passed down through generations. This linguistic diversity contributes to the development of unique cultural practices within different orca communities.

Intelligence and adaptability: Morton's research revealed the remarkable cognitive abilities of killer whales:

• Problem-solving skills in hunting techniques
• Complex social behaviors and relationships
• Ability to learn and pass on cultural traditions
• Emotional intelligence, as evidenced by their responses to loss and joy

3. The Impact of Captivity on Orcas and the Ethics of Marine Parks

I knew where whales belonged, and it wasn't in captivity.

Physical and psychological effects: Captivity severely impacts orcas' well-being:

• Limited space compared to their natural range
• Inability to engage in natural behaviors
• Separation from family units
• Increased aggression and stress-related behaviors

Breeding issues: Morton observed the difficulties captive orcas faced in successfully raising offspring, highlighting the importance of learned behaviors in wild populations.

Ethical considerations: The research raised questions about the morality of keeping such intelligent, social creatures in captivity for human entertainment. Morton's experiences with both captive and wild orcas led her to advocate for the end of orca captivity and the importance of studying these animals in their natural habitats.

4. Pioneering Field Research Techniques in the Broughton Archipelago

Every day I continue to watch and listen for killer whales. I hope that I do not have to watch them die out.

Innovative methods: Morton developed unique approaches to studying wild orcas:

• Using hydrophones to record underwater vocalizations
• Identifying individual whales through dorsal fin and saddle patch markings
• Tracking pod movements and behaviors over extended periods

Challenges of field work: Research in remote areas presented numerous obstacles:

• Harsh weather conditions
• Equipment limitations and failures
• Difficulty in locating and following whale pods

Long-term commitment: Morton's dedication to living in the field allowed her to observe seasonal patterns, population changes, and long-term trends in orca behavior and ecology. This continuous presence provided invaluable insights into the lives of these elusive creatures.

5. The Intricate Relationship Between Salmon and the Coastal Ecosystem

Salmon are a living artery keeping the entire coastline alive, connecting the Pacific gyre nutrients to the mountainous watersheds; they are the blood flowing through its body.

Keystone species: Salmon play a crucial role in the coastal ecosystem:

• Primary food source for orcas, bears, eagles, and other wildlife
• Nutrient transfer from ocean to forest ecosystems
• Economic importance for human communities

Life cycle: The salmon's journey from rivers to ocean and back is essential for the health of both aquatic and terrestrial environments. Their decomposing bodies nourish the soil, contributing to the growth of massive coastal forests.

Threats to salmon populations: Morton observed several factors endangering wild salmon:

• Overfishing
• Habitat destruction due to logging and development
• Climate change affecting water temperatures and ocean currents
• Competition and disease from introduced farmed salmon

6. The Devastating Effects of Salmon Farming on Wild Populations

To the fish farmers, the old-timers had done nothing but reveal all the best farming spots—put them on a map and colored them red, in fact.

Environmental impact: Salmon farms introduced numerous problems:

• Spread of diseases and parasites to wild populations
• Pollution from fish waste and chemicals
• Escaped farmed salmon competing with wild stocks
• Acoustic harassment devices driving away native marine life

Economic consequences: The rise of salmon farming led to:

• Decline in wild salmon populations
• Loss of traditional fishing livelihoods
• Shift in coastal community economies

Government complicity: Morton's research revealed a disturbing lack of regulation and oversight by government agencies, often prioritizing industry interests over environmental protection and the health of wild salmon populations.

7. Personal Tragedy and Resilience in the Pursuit of Scientific Knowledge

Were it not for Jarret, I would have slumped in a corner and not moved for two years.

Loss and grief: The tragic death of Morton's husband, Robin, during a diving accident profoundly affected her life and research. The loss threatened to derail her work and life in the archipelago.

Perseverance: Despite the immense personal tragedy, Morton found the strength to continue her research, driven by:

• Responsibility to her son, Jarret
• Commitment to understanding and protecting orcas
• Support from the coastal community

Renewed purpose: Over time, Morton's grief transformed into a renewed dedication to her work. She expanded her research to include the impact of salmon farming on the ecosystem, combining her scientific pursuits with environmental advocacy.

8. The Importance of Community in Remote Coastal Living

Communities like Echo Bay thrive on the currency of neighborly help.

Mutual support: Life in remote coastal areas relies heavily on community cooperation:

• Sharing resources and skills
• Collective problem-solving
• Emotional support during hardships

Diverse backgrounds: The coastal community included a mix of:

• Traditional fishermen and loggers
• Environmental researchers
• Alternative lifestyle seekers

Adaptation to isolation: Residents developed unique ways to overcome the challenges of remote living:

• Creative use of limited resources
• Development of multiple skills to ensure self-sufficiency
• Strong communication networks despite physical distances

9. The Emergence of Offshore Orcas and New Scientific Discoveries

As the whales continued to shun the archipelago, I began to worry about what might have happened. Even though I'd always dropped whatever I was doing to follow them, I'd always assumed that the whales would be here. I had taken them for granted.

New orca population: The discovery of offshore orcas in the late 1980s and early 1990s opened up new avenues of research:

• Distinct physical characteristics from resident and transient orcas
• Unique vocalizations and behaviors
• Possible specialization in shark predation

Changing ecosystem: The appearance of offshore orcas in coastal waters raised questions about:

• Shifts in prey distribution
• Potential impacts of climate change on orca populations
• Interactions between different orca ecotypes

Ongoing mysteries: The offshore orcas highlighted how much remained unknown about killer whales, emphasizing the need for continued research and protection of marine ecosystems to ensure the survival of these remarkable creatures.
