Know Before You Go
Whether you're preparing for your upcoming expedition or simply want to learn more about Churchill's beluga whales and Arctic conservation efforts, these resources offer a closer look at the wildlife, landscapes and research that define this experience. Discover why thousands of belugas gather in the Churchill River estuary each summer, learn how scientists identify individual whales and study their underwater communication, and explore how long-term research is helping us better understand these remarkable marine mammals and their changing Arctic habitat.
Why Is Churchill One of the Best Places in the World to Study Beluga Whales?
Each summer, some 3,000 beluga whales gather in the Churchill River estuary along the western shore of Hudson Bay, transforming its cold northern waters into one of the Arctic's great wildlife spectacles. Drawn to the estuary's warmer, shallow waters to molt, socialize and tend to their young, these famously vocal whales offer researchers an extraordinary opportunity to observe their behavior, social relationships and seasonal habitat use.
Scientists at Assiniboine Park Conservancy are investigating how individual belugas interact, communicate and return to the estuary across successive summers. Through photo identification, underwater imagery, acoustic recordings and environmental measurements, researchers are building a clearer picture of the whales' social lives, visible health indicators and movements. Distinctive scars and markings help identify individual whales, while underwater recordings reveal the whistles, clicks and calls that earned belugas the nickname "canaries of the sea."
By participating in this long-term research, travelers help scientists document how belugas use their summer habitat and respond to changing environmental conditions. These observations contribute to a growing scientific record that can inform conservation efforts as warming Arctic waters and increasing marine activity bring new challenges to Hudson Bay's belugas.
