David Tattoni and Diane Renshaw band birds along Corte Madera Creek, above Searsville Lake. Trail 12.
Information gathered during and after bird banding is valuable in learning about the birds, their habits, and their health. It is useful to better target conservation efforts in the future. David Tattoni is a trained and experienced bird bander, and holds federal and state permits to conduct this activity. From what I saw, he is respectful of the birds, and careful to treat them gently.
