Purple Martins have been in long-term decline in California due to factors such as habitat loss, competition with European Starlings, and dwindling food supply due to neonicotinoid insecticide use. Dan Airola has been studying and working to conserve the last Central Valley population, which nests in elevated freeways and overpasses in Sacramento.

Islands play a key role in both the evolution of new avian species and the extinction of others. Although over 80 percent of bird species live on continents, 92 percent of extinctions since 1500 have been on islands. Join us to view some marvelous island species and learn about the conservation issues unique to islands.

Only male birds sing, right? Wrong! In fact, this widespread notion has a lot more to do with human cultural and geographic biases than it has to do with nature. In this talk, Nathan Pieplow explores the often-overlooked songs of female birds.

Eric Schroeder will take you on a tour of this amazing island, home to 308 species of birds, 108 of which are endemic. Endemism isn’t limited to individual species but, remarkably, extends to the family level; Madagascar has six endemic avian families: the mesites, the asities, the vangas, the tetras, the ground rollers, and the cuckoo roller (which has only one species—the Cuckoo-roller—in the family.)

Dive into the world of Alcatraz seabirds! Learn about the several species that breed on the island each spring and summer, and how we can protect them from climate change and other threats.
