To Southern California, Brazil, and Back: First GPS Tracking of Oregon Vesper Sparrow and Western Purple Martin Migration

Join the Redwood Region Audubon Society on Thursday, January 16 at 7:00 p.m. for a program entitled “To Southern California, Brazil, and Back: First GPS Tracking of Oregon Vesper Sparrow and Western Purple Martin Migration” by Sarah Rockwell. One of the biggest challenges in identifying ways to help migratory birds is that we don’t know where they are most of the year. Without this basic information, it is challenging to identify and prioritize conservation actions. Archival, lightweight GPS tags placed on small songbirds have been available for about a decade, and they are revolutionizing our understanding of bird migration and migratory connectivity. The Klamath Bird Observatory (KBO), along with partners at USFS, USGS, Cape Arago Audubon, and Avifauna Northwest, is using these GPS tags to track the migratory routes and overwintering locations of both Oregon Vesper Sparrow and Western Purple Martin, two imperiled subspecies unique to the Pacific Northwest. These are the first studies with these subspecies—the first to track them with GPS technology year-round! These birds have returned with fascinating information, revealing discoveries about their incredible journeys, including unexpected lengthy fall stopovers, and for Purple Martins, winters on the beach in southeastern Brazil. In this talk, Sarah will share photos and maps from this research, and give a peek into the amazing window we now have into the incredible voyages these birds undertake. Dr. Sarah Rockwell is a Senior Research Biologist at KBO, where she manages several research programs studying the ecology of bird species of conservation concern, and monitoring birds at riparian, oak, and coniferous restoration sites. Sarah manages KBO’s Oregon Vesper Sparrow research program, studying nest success, survival, and habitat needs to better understand the causes of their decline and potential conservation actions. Sarah joined KBO in 2013 after completing her PhD at the University of Maryland and Smithsonian Migratory Bird Center, where she studied the ecology of the then-endangered Kirtland’s Warbler in her home state of Michigan. She earned her BA in Biology in 2002 from Kalamazoo College, where she fell in love with birds during her study abroad experience in Ecuador. She lives in Ashland, Oregon, with her husband and four-year-old daughter. Programs are held at Six Rivers Masonic Lodge, 251 Bayside Road, Arcata, or via the Zoom link www.rras.org. Drinks and goodies are served at 7:00 p.m., the program begins at 7:30.
