Our guest on January 27 was Professor Daniel Roby of the Oregon Cooperative Fish and Wildlife Research Unit, in the Department of Fisheries and Wildlife at Oregon State University. We had a fascinating conversation about seabird feeding strategies, energetics, and the “wreck” of Cassin’s Auklets.
In the second half of the show, Dr. Roby told us the amazing story of how a dredge spoil site became the site of the world’s largest Caspian Tern breeding colony, threatening the fragile recovery of salmonids in the Columbia River system, and how he and others used a “push-pull” strategy to move the entire colony to a different site. The effort succeded beyond expectations and dramatically reduced tern predation on salmonids.
