The poet Nikki Giovanni once said that she spent a lot of time learning about bird watching. Placing these birdbath basalt rocks in my new garden has made me want to do the same. We’ve created our own little aviary hammam out front and when I’m around I try to sit very still so I don’t frighten the winged skinny-dippers away. Just wish I knew their names. I’d like to be a better hostess. Any suggestions for beginner bird watching guides?
