Query: Best I've seen

The editorial review basically says it all. I'm using the book quite a bit -- I'm trying to attract birds that will eat insect pests. Few other sources have such detailed information about feeding habits, and the information on houses is quite adequate, although you can find birdhouse designs which are much more visually appealing (to humans!) in other books. The one thing I really wish they had done is to put the pests in the index; finding what pests birds like particular to eat requires tedious entry-by-entry searching.
