Do you know how many types of colors there are on birds, and how these colors are produced? Did you know that humans and birds see colors in different ways and that birds use colors and patterns in a wide range of ecological and behavioral contexts? This will be a fun, and colorful, talk that leaves you never seeing birds the same way again.

David Lukas will introduce you to the marvelous world of bird colors and patterns. He is an expert naturalist who is well known for his talks, walks, and classes. He is also the author of many books and articles on a wide range of natural history topics, including the books Bay Area Birds and Sierra Nevada Birds. His most recent book, Language Making Nature, is an exploration of tools and ideas for creating new words.
