A KBO Presentation – A West Coast Migratory Anomaly, Bear Divide

Join us on February 24th at 6 pm for a presentation on Bear Divide by KBO’s Science Director Dr. Ryan Terrill. Bear Divide is a recently discovered migratory bird concentration point near Los Angeles, CA. It is one of the only places in the western United States where you can see bird migration during daylight hours. Calling Bear Divide a migratory hot spot would be an understatement. Every year — roughly between March 15 and June 15, with peak migration between April 10 and May 20 — thousands of birds funnel through the narrow pass. It offers a unique learning opportunity, such as how timing, weather, climate, sex, age, and other factors affect migratory patterns. The area attracts as many as 13,000 tanagers, orioles, buntings, grosbeaks, and warblers on a single day. One of the fascinating aspects of Bear Divide is the sheer variety of bird species it attracts. From the diminutive hummingbirds to the impressive birds of prey, each species adds a unique dimension to the study of migration. Dr. Ryan Terrill will discuss the discovery, implications, and ongoing research at this fascinating and unique hotspot for bird migration.

This is a free event with in-person and Zoom options available. Register below.

NEWS RELEASE: For Rufous Hummingbirds, migration looks different depending on age and sex

CORVALLIS, Ore. – Plucky, beautiful and declining in numbers at about a 2% annual rate, the Rufous Hummingbird makes its long annual migration in different timing and route patterns based the birds’ age and sex, new research by Oregon State University shows. The findings, published in the journal Avian Conservation & Ecology, are important because the more that is known about how Rufous Hummingbirds migrate, the more that can be done to ensure birds of each age and sex category have the resources they need each year on their journey up and down the western part of North America.
