As some of you know, I've been casually researching Northern Shrikes in the Ashland area since 2005 and have trapped and banded over 100 individuals during that time. I mark all birds with color bands on one or both legs to allow for field identification without recapture, which has been invaluable to understanding territory establishment, site fidelity, survivorship, etc. This past Sunday I finally was able to confirm the band combination for an adult female that has been on territory here all winter. And I'm excited to report that I first banded her as an adult on the same territory back on 17 March 2006! I've seen her on this territory at least part of every year since. She is at least 6 years, 8 months old and represents the oldest known individual of this poorly-studied species in North America. Here are some photos of the bird from Sunday. You can't see the bands here but I got the color combo by watching the bird eat a cached vole for 10+ minutes, moving around frequently in the process. Not extraordinary photos but fun to document a memorable day for me. http://www.pbase.com/rbrady/image/132940411 http://www.pbase.com/rbrady/image/132940410 http://www.pbase.com/rbrady/image/132940409 Ryan Brady Washburn, Bayfield County, WI http://www.pbase.com/rbrady #################### You received this email because you are subscribed to the Wisconsin Birding Network (Wisbirdn).
