2019 Friday Keynote | Sharon Beals, a San Francisco-based artist who has photographed nests of various species, all collected sometime in the past two centuries and preserved in the collections of the California Academy of Sciences, the Museum of Vertebrate Zoology at Berkeley, the Western Foundation of Vertebrate Zoology and the Cornell University Museum of Vertebrates, which are highlighted in her book, Nests: Fifty Nests and the Birds That Built Them. Much of Beals’ work has an environmental bent. For a past project, she photographed still lifes made from plastic trash floating in lakes and the ocean. Beal became interested in birds when reading Living on the Wind: Across the Hemisphere with Migratory Birds, a 1999 book by naturalist Scott Weidensaul. She learned about the incredible migrations of Arctic terns and blackpoll warblers and also about the habitat and food supply loss along many of the species’ routes. Much of Beals’ work has an environmental bent. For a past project, she photographed still lifes made from plastic trash floating in lakes and the ocean. Beals explains in an artist statement. “It was only after making the first photograph of a nest, drawn to its palette and messy, yet graceful and functional form, that I knew I had found my medium—or at least a way that I could be a medium for the birds.” See her full bio.

2019 Saturday Keynote | Kenn Kaufman, a lifelong naturalist, is the originator and editor of the Kaufman Field Guides series. His fascination with birds developed at the age of six, and he went on to become one of the world's best-known bird experts, but his interests extend to every area of nature. In addition to his work on the field guides, Kenn is also a Field Editor for Audubon Magazine, and a regular columnist for BirdWatching and Birds and Blooms.
Kaufman burst onto the North American birding scene as a teenager, hitch-hiking around the continent in pursuit of birds, an extended journey that was later chronicled in his memoir Kingbird Highway. Establishing an early reputation as an expert on bird identification and distribution, in 1984 he became associate editor of the journal American Birds, which was then published by the National Audubon Society, and began teaching birding workshops throughout the United States and Canada. During the same period he also began leading international birding and nature tours, eventually leading multiple trips to all seven continents and many oceanic islands. His first book, A Field Guide to Advanced Birding, published in the Peterson series in 1990, drew wide acclaim, and in 1992 he became the youngest person ever to receive the lifetime achievement award of the American Birding Association (the award was later renamed, and he received it again in 2008). Since the late 1990s, most of his attention has gone into the Kaufman Field Guides. Countless hours in the field doing research and photography are followed up with countless hours of writing, editing, and design work, collaborating with experts in each subject to ensure the highest quality in the finished books. Aside from the field guides, Kenn's best-known book is his Kingbird Highway. Published by Houghton Mifflin in 1997 and still in print, it has become something of a cult classic, especially among young birders. It tells the story of his adventures as a teenager in the 1970s, thumbing rides all over North America in an obsessive search for birds. A memoir of a different kind is his Flights Against the Sunset, published by Houghton Mifflin in 2008. This book tells a series of stories "from that frontier where the world of birds intersects with the world of the humans who pursue them."

She serves as President of Madrone Audubon Society in Sonoma County and Chairs the Board of the conservation nonprofit, Paula Lane Action Network, protecting sensitive badger habitat on Paula Lane Nature Preserve in West Petaluma.
