This farm relies on birds — not pesticides — to control pests

Dennis Tamura never set out to be a bird-watcher. He’s been a farmer for over 35 years, and he and his wife grow organic vegetables and flowers on Blue Heron Farms outside Watsonville. But birds have become a part of the farm’s ecosystem. About 15 years ago, a bird-loving neighbor put up small wooden bird boxes on the fence posts that line Blue Heron Farms, and Tamura just started noticing the tree swallows and Western bluebirds that came to visit. Today, he points out a fluffy baby tree swallow, its comically large yellow mouth peeking out of a hole in the box.
