A brief conversation with the young lady in the visitor's center as to why they posted the sign against feeding, she said she thought it was to keep the birds wild, and due to concern about other animals, ie, coyotes, being attracted to the seed. We didn't pursue it any further.
Seen at the bridge today from noon to 1:30 were Tree and Song Sparrows, BC Chickadees, Am. Goldfinch, House Finches, and Magpies.
