Have you seen the actual Wild Parrots of Telegraph Hill? What about the Chestnut-backed Chickadee? Or the Pygmy Nuthatch? How about the California Towhee?
These tweeters (and many more) like to hang out in San Francisco, so if you're curious about what they look like, a good place to start is with a bird feeder.
We love Amy Adams's glazed ceramic Perch Birdfeeder because it's beautiful and scaled for city living. Smaller and less expensive than Vessel's classic Malcolm Leland bird shelter, Perch is just right for a small urban garden, balcony or fire escape.
