Found these while playing at the Presidio in San Francisco: Winged Wisdom – 3 sites that describe robin behavior. Each letter is framed with a steel armature and mesh netting and is filled with straw, providing nesting material for the American robin.
I love living in the Bay Area!

You’re right! You never know what you’re going to find lurking around the next corner! (I’ll bet a lot of other bird species will be taking advantage of all this free nesting material.) /Gary
