The bonds within these matrilines are incredibly strong, with mothers, grandmothers, aunts, and siblings all working together to support and care for the youngest members. This close-knit family structure is a key part of what makes the southern resident orcas so unique and fascinating to researchers like Giles.
But despite their intelligence, adaptability, and complex social structures, the southern resident orcas are facing a multitude of threats that are pushing them closer to the brink of extinction. The decline of Chinook salmon populations, pollution in the Salish Sea, and increasing boat traffic in their habitat are just a few of the challenges that these magnificent creatures are up against.
Giles and her team are working tirelessly to study and understand these threats in order to develop conservation strategies that will help save the southern residents. Through years of research, they have gathered valuable data on the whales’ health, behavior, and diet, which has helped shed light on the ways in which human activities are impacting their survival.
However, the future of this critical research is now in jeopardy. The Trump administration’s actions have put many conservation studies, including those focused on the southern resident orcas, at risk of being stalled or halted altogether. This comes at a time when the whales need science-based conservation efforts more than ever to prevent their extinction.
As Giles steers her boat through the waters of the Salish Sea, with Eba the dog at her side and her research equipment at the ready, she is a beacon of hope for the southern resident orcas. Her dedication to studying and protecting these majestic creatures is a testament to the importance of science in conservation efforts.
As we navigate the complex challenges facing the southern resident orcas and other endangered species, it is essential that we continue to support and prioritize science-based research and conservation efforts. The future of these incredible animals depends on it. Killer whales, also known as orcas, are majestic creatures that roam the oceans in pods led by older females. These matriarchs can live for over a century, more than twice as long as most males in their pods. The southern residents, comprised of three pods: J, K, and L, have a unique culture that sets them apart from other killer whale populations.
Historically, the southern residents spent much of their time in the Puget Sound and near the San Juan Islands, often gathering as a “superpod” during the warmer months. In the colder months, they tend to split up and explore the outer coasts of Washington State, Oregon, and even California. Despite the distance between them, these pods are connected by their shared language, diet, habits, and behaviors, creating a culture that is distinct from any other population of killer whales.
Humans and killer whales have a long and complicated history. Indigenous communities of the Pacific Northwest have lived alongside orcas for thousands of years, viewing them as sacred beings. However, settlers in the 1800s saw orcas as competitors for fish and sought to exterminate them. The capture of killer whales for entertainment in the mid-20th century led to a significant decline in the southern resident population, with numbers dropping to just 71 whales by the mid-1970s.
Efforts to protect and conserve the southern residents have faced challenges. Pollution in the Salish Sea, caused by urban, industrial, and agricultural runoff, has led to a buildup of toxic chemicals in the whales’ blubber. Additionally, a decline in their primary food source, Chinook salmon, has further threatened their survival. The constant disturbance from boat noise in the waters has also impacted the orcas’ ability to hunt for food.
Researchers have been studying the southern residents to understand the factors contributing to their decline. Acoustic devices attached to the backs of orcas have provided insights into how noise pollution affects their foraging behavior. Female orcas, in particular, are known to avoid hunting in noisy waters, leading to further challenges in finding enough food to sustain the pods.
Despite these challenges, efforts are being made to protect the southern residents and ensure their survival. Conservation measures aimed at restoring Chinook salmon populations and reducing pollution in their habitat are crucial for the long-term health of these iconic marine mammals. By understanding the unique culture and behaviors of the southern residents, we can work towards a future where these magnificent creatures can thrive in their natural environment. The decline of the southern resident killer whales is a complex issue that is influenced by multiple factors, including pollution, vessel disturbance, and lack of food. These factors have been identified through decades of research as key contributors to the decline of the southern resident population, which now stands at only 74 individuals. In contrast, the northern resident killer whales, who spend more time in quieter, less polluted waters off the coast of British Columbia, have seen their numbers double since the capture era.
One of the major challenges facing the southern residents is the impact of vessel noise on their ability to echolocate and find food. When vessel noise is too loud, it can mask the whales’ ability to navigate and locate prey. This can have serious consequences for their ability to feed and ultimately survive.
Research biologist Kim Parsons has been studying the southern resident orcas since the early 1990s. Parsons works at NOAA’s Northwest Fisheries Science Center and has been instrumental in collecting data on the health and behaviors of these iconic marine mammals. One of the methods used by Parsons and her team to study the orcas is to collect and analyze their poop.
Collecting orca poop may sound like a strange task, but it is actually a valuable source of information for researchers. By analyzing the scat, scientists can determine which individual whale produced the sample, measure their levels of toxic chemicals, and assess their overall health. Hormone analysis can also reveal information about the whales’ reproductive health, which is crucial for understanding the population dynamics of the southern residents.
In addition to studying the health of the whales, researchers also use scat samples to analyze the diet of the orcas. By examining fragments of DNA in the samples, scientists can identify the exact species of fish that the whales have been eating. This information helps researchers understand the dietary preferences of the southern residents and how changes in prey availability may be impacting their overall health and survival.
Overall, the research being conducted on the southern resident killer whales is helping to shed light on the complex interactions between pollution, vessel disturbance, and lack of food on the health and survival of these iconic marine mammals. By studying their behaviors, health, and diet, scientists are working towards a better understanding of how to protect and conserve the southern resident population for future generations. Recent research has shed new light on the importance of chum and coho salmon in the late summer and early fall for the southern resident orcas. Scientists have found that these species are crucial parts of the orcas’ diet during this time period. However, more samples are needed, especially between October and April, to fully understand the whales’ dietary habits throughout the year.
Deborah Giles, a researcher at The Seadoc Society, emphasizes the need for a comprehensive understanding of the orcas’ diet to ensure their well-being year-round. By knowing what, where, and when the whales eat, fishery managers can make informed decisions to adjust fishing practices to support the orcas’ nutritional needs. For example, if it is known that the southern residents heavily rely on chum salmon in the Puget Sound in November, fishing quotas could be adjusted to protect this stock.
In a recent expedition, researchers tracked an orca named Eba as she led them to a potential fecal sample from the whales. Despite Eba’s excitement and effort, the sample turned out to be inconclusive, highlighting the challenges of studying the orcas’ diet in the wild. Scientists like Amy Van Cise from the University of Washington are using genetic analysis of whale feces to identify the specific salmon runs that the southern residents depend on the most. This detailed information could help prioritize conservation efforts for these crucial salmon populations.
However, the future of research funding for projects like these is uncertain. In recent years, federal science agencies have faced significant budget cuts and grant cancellations, jeopardizing ongoing research efforts. Van Cise, who relies on funding from agencies like NOAA and the NSF, expresses concerns about the impact of dwindling research funding on her career and the progress of her studies. Without adequate financial support, critical research projects aimed at understanding and conserving endangered marine species like the southern resident orcas may be at risk.
Despite the challenges, researchers like Giles and her team continue to persevere in their efforts to study and protect orcas and their prey. Projects such as using drones to collect breath samples from orcas and infrared cameras to monitor their health show promise for advancing our knowledge of these magnificent animals. With continued support and funding, scientists hope to make significant strides in understanding and conserving the marine ecosystems that these iconic whales depend on. In the world of wildlife conservation, staff scientists play a crucial role in conducting research to protect vulnerable species, while managers work on crafting recovery plans and designating critical habitat. However, in 2025, the Trump administration made significant cuts to the agency, resulting in the loss of over 2,000 employees. One of those affected was Lynne Barre, the southern residents’ recovery coordinator for two decades. Forced into early retirement due to the mass layoffs and frozen budgets, Barre described the situation as being akin to being on a burning pirate ship with no choice but to jump off.
The Northwest Fisheries Science Center and the West Coast Regional Office, where much of the southern resident work takes place, lost nearly 30 percent of their staff, including seasoned researchers with years of expertise. This loss has had a significant impact on the workforce, leaving the southern residents in a precarious position. Despite the challenges, scientists agree that the southern residents cannot afford to wait. With the population at a low level, urgent action is needed to ensure their survival.
In 2025, Washington State implemented a new regulation requiring boats to stay at least 1,000 yards away from the southern residents to minimize disturbance during hunting. While this measure aims to support the whales in their natural habitat, it will require ongoing research to assess its effectiveness. Barre emphasized the importance of a strong scientific foundation to guide conservation efforts, especially given the fragile state of the population.
During a close encounter with the southern residents, a mother and baby orca approached the researchers’ boat, providing a poignant reminder of the beauty and vulnerability of these creatures. As the whales swam gracefully alongside the boat, the researchers marveled at their majestic presence. Despite the challenges they face, the researchers remain committed to protecting the southern residents and working towards their recovery.
As the sun set on another day of fieldwork, the researchers reflected on the decades they have spent studying and advocating for the southern residents. At Lime Kiln Point State Park, a place once teeming with orcas, the researchers looked out at the water, hoping for a future where breaching whales would once again be a common sight. With determination and dedication, they continue their efforts to support the recovery of the southern residents and ensure a future where these magnificent creatures thrive in their natural habitat.
