In Search of Spew, Poo, and Goo: Determining Orca Diet from What They Leave inTheir Wake
Join us for a presentation by Brad Hanson, NOAA Fisheries, about the diet of southern resident orcas. Brad will present new findings based on genetic analysis of prey and fecal samples collected in Puget Sound. This data is critical to the recovery of the population, which was listed as Endangered in 2005.

In October each year, the southern residents (J, K and L pods) begin their seasonal forays into Puget Sound, where they spend up to two days, a few times each month. From samples collected in the orcas' wake, Brad and other researchers are able to determine what the orcas are eating.

Brad will discuss these innovative research techniques, what we are learning from the data they yield, and what it means for the orcas' long-term recovery. This is the first time the Puget Sound results have been presented. Join us for this fascinating and timely talk, and be the first to hear what the research is showing.

Help us celebrate the return of the southern resident orcas to our local waters, and learn what you can do to protect them.

He also holds an M.S. in Fisheries from the University of Washington and a B.A. in Zoology also from the University of Washington.  Brad is an ecologist and is currently studying foraging and habitat use of Southern Resident killer whales and health assessment of harbor and Dall's porpoises.

About The Whale Trail
The Whale Trail (www.thewhaletrail.org) is a series of sites around the region where you may view orcas and other marine mammals from shore. Our mission is to inspire appreciation and stewardship of whales and our marine environment. The Whale Trail is being developed by a core team of partners including People For Puget Sound, NOAA Fisheries, Washington Department of Fish and Wildlife, the Seattle Aquarium, and the Whale Museum.
