Monika Wieland Shields, Co-Founder and President of Orca Behavior Institute on San Juan Island, will be presenting about the complex behaviors of Puget Sound orcas. She’s observed the Southern Residents since 2000, becoming known locally for her whale photography and blog, Orca Watcher. In addition to being interested in acoustics, she’s keen to study the changing pod structures as previously stable groups have started forming smaller factions.
