Hi Tweeters, first of all, oops! I sent a web site tht was for a blue bird house . I apologize. Here is a much better site. Has different kinds of bird houses. Go to: http://www.npwrc.usgs.gov/resource/tools/ndblinds/ndblinds.htm Happy building! There are also books you can buy tha have bird house plans in them. Betty Boyd Chimacum.
