I live in Southern California. How do you determine the size of the holes for a driftwood birdhouse for all the various birds?

Answer

Many small cavity nesting birds will move into a birdhouse with a 1-1/2" diameter entrance hole. For additional information, the Cornell Lab of Ornithology offers a list of common cavity nesters with recommended dimensions for nest boxes and entrance holes. Here's the link:
