The screech owl is a misnomer, it makes a horse-like whinny instead. This box is made with cypress. You can hang it as low as 10 feet off the ground. If you have squirrels you might need to wrap the tree above and below with sheet metal, and maybe even put a metal sheet on the roof so they can't jump down from above.The plans are here: https://www.audubon.org/news/how-build-screech-owl-nest-boxThe dimensions are in the pdf here: https://nas-national-prod.s3.amazonaws.com/screech-owl-nest-box.pdf
