Just a quick run through of the potential species that could be attracted by nest boxes.  Remember, not all birds use cavities/nest boxes, so there may be many others nesting nearby (as we saw from old nests in the trees and shrubs).  We want to minimize House Sparrow and Starling use.  We want to minimize predation or nest box takeover by squirrels, mice ….  We don’t want to attract potential predators (larger owls) to Zoo grounds.  Consider ease of set up, take down and opening for cleaning or repairing.  Consider a similar shape of design of most boxes but with appropriate dimensions for the species and appropriate hole size.  The Purple Martin box or plastic gourds will be a little different.  Consider having the entrances to the bird boxes facing east to southeast, less rain gets in due to weather patterns
