I recently wrote about a new birding David Lukas’s Bay Area Birds book, an informative guide about the birds of the Bay Area last month in the posting A Most Useful Guidebook For Bay Area Birds. David is doing a series of talks and a birding field trip in the north bay next month.
April 9, A Talk on Bird Feathers and Bones
Napa-Solano Audubon Chapter
Vallejo, 7 p.m.

Have you ever found a bird feather or bone and wondered what you could learn from it? This talk will cover bird bones, feathers, and muscles and how they work together to help a bird fly and live in its environment. Expect to learn about the inner and outer workings of birds.

April 10, Bird Biology and Breeding Season Behavior

This evening event will be an unusual hybrid that combines some bird biology (how bones, feathers, and muscles work to help birds fly), along with a free-ranging discussion about as many aspects of the bird breeding season as we have time to cover, including topics like courtship, nesting, egg-laying, and chick development. This is a free talk for wildlife center volunteers but the public is welcome (donations requested).
