Unearthing the Mysteries of Pygmy Blue Whales Through Citizen Science
Timor-Leste's local fishers and scientists collaborate to study elusive marine giants.
The stunning waters of Timor-Leste are becoming a hub for research on one of the ocean's most mysterious creatures, the pygmy blue whale. For about two months each year, the local fisherman Faustino Mauloko da Cunha and his son, Zacarias, take to their dugout canoe in search of these marine giants, armed with binoculars and a telephoto camera. When they spot a whale, the action begins. A drone is dispatched by a research team led by Australian marine ecologist Karen Edyvane to capture aerial images—essential data that helps in studying this elusive species.
Timor-Leste, an archipelago located between South East Asia and the South Pacific, is home to one of the highest concentrations of marine mammals in the world. Each year, during the migration months of October and November, hundreds of pygmy blue whales journey through the region, traveling thousands of kilometers from southern Australia to the Banda Sea. Despite this vastness, the area was under-researched until Prof. Edyvane initiated the monitoring program in 2014.
The local citizen scientists, trained in survey methods and equipped with modern technology, have contributed immensely to the project, spotting nearly 3,000 pygmy blue whales over the last decade. The project began with a Facebook group and has grown to include local fishermen, students, and dive tour operators—all collaborating to document whale behaviors. Notably, for the first time, the team captured underwater footage of a mother nursing her calf, providing groundbreaking insights into the reproductive behaviors of the species.
This year, a "research station" was established at the da Cunha's family home, offering an easy way to monitor whale activity continuously. The significance of local involvement in research cannot be overstated, as wildlife scientist Vanessa Pirotta emphasizes the insights gained from citizen scientists' observations powered by drones and social media.
The increase in whale research has amplified local tourism, with whale-watching tours becoming highly sought after. As demand has surged, local non-profits stress the need for regulations to protect marine life. The government intends to utilize the findings from Prof. Edyvane's work to create protective measures for these majestic creatures. With potential for eco-tourism to boost the impoverished economy, Faustino and Zacarias have already embraced new income opportunities, engaging students and tourists and sharing their knowledge of local marine life.
Prof. Edyvane plans to continue training local residents, ensuring that they play an integral role in conserving marine ecosystems. The positive relationship developed between the locals and visiting tourists reflects the deep connection they all share towards responsible environmental stewardship.
