Tweeters: I can't find my various plans for nesting boxes. Would like to
know the diameter opening to accomodate screetch owl, kestrel, or whatever
would like to use it. Is there a generic one size fits all for small to
medium sized owls? Or would someone send me a short list of species and
diameters? Thank you.
