The Oregon Chapter of the American Cetacean Society is having its monthly speaker series meeting on Saturday, Sept. 11, at 10 a.m. The meeting will be held via Zoom and is free to the public.

The topic will be “Beyond Song: Exploring Humpback Whale (Megaptera novaeangliae) Calls on the Hawaiian Breeding Grounds,” presented by Sabena Siddiqui. Register to receive the Zoom link and password by going on Eventbrite —

Humpback whale song has fascinated both the public and scientists for decades and has been the focal point of the acoustic research in this species. However, the humpback whale communication system is made up of other sounds other than song. Humpback whales also produce a variety of calls (also known as “nonsong calls” or “social sounds”), which have been historically less studied. While song is produced by only males and primarily on the breeding grounds, these sounds can be detected on breeding, feeding and migrating grounds. This talk will summarize research into humpback whale calls off Hawaii over a 10-year period using underwater video and audio recordings.

Siddiqui has always been fascinated with questions about animal communication. She was born in India and raised in the U.S., and she chased her passion for these questions through participation in projects involving manatee cognition and cetacean communication and distribution in locations such as Egypt, The Bahamas, Florida, the North Atlantic and Hawaii. Her interest in humpback whales took her to Hawaii, where she recently completed her master’s project on humpback whale calls on the Hawaiian breeding ground. She is involved with nonprofit work as a board member of the American Cetacean Society, where she has served as the organization’s student chair for 10 years, and she represents the organization at the International Whaling Commission. To promote gender equality and diversity in science, she served as the lead editor of the first publication highlighting women cetacean scientists through the ACS Whalewatcher.

The American Cetacean Society protects whales, dolphins, porpoises and their habitats. The nonprofit organization was founded in 1967 and is headquartered in San Pedro, Calif. Information on the ACS can be found on the website: You can also find them on Facebook now at American Cetacean Society-Oregon Chapter.
