Bay seniors on the lookout for a new diversion might consider joining the throngs who have made bird watching the #1 hobby in the US. I’d check Google for classes or just head out to any of the many great winter birding sites around the Bay Area. We are on the Pacific Flyover making avian life here particularly rich. Here are ten of the best viewing spots. Birding is not just an aesthetic thrill. The Geezer was surprised in Marin’s Tennessee Valley recently to see an egret gulping down a ground squirrel.
