Bird Houses We’ve Built

Finch House We build a large number of these finch houses because they were so successful and easy to put up and to clean.  This was the house, hung by the back door at which we saw two baby birds fledge in 2008. The house is made from ¼” plywood.  We adjusted the sizes slightly to build more houses from a single 2’x4’ sheet of plywood. Side (S): 5 ½” w x 5 ¼”h   need two of these for each house Front (F): 4 ½” x 4 ½” square. 1 ½” hole centered 1 ¼” below top  Top (T): 4 ½” w x 5 ½”h Bottom (B): 4 ½” w x 6 ½”h. Rear (R): 4 ½” w x 6 ½”h.  Drill a ¼” nail hole 1” below the top Attach Sides on the outside of the Front, Bottom and Rear using wood glue.  Do not glue the Top.  Nail through the Sides into the Top about ¼” from the Rear.  The Top should be able to pivot to open to allow easy cleaning.  The Top should slope slightly back to front and overhang the Front so rain drips off the slight lip.
Woodpecker House The tricky part of the woodpecker house was the tall pole.  We erected a 16-foot 4x4, set in concrete.  We attached a number of houses before erecting the pole.  That was easier than using a tall ladder.  The woodpeckers used the houses for a few years in the mid-2000s, but then moved on to more natural settings, I suppose.  Bees took over one house for one summer. We used rough 6” fence board. 4 ½” wide.  The houses were: Side (S): 4 ½”w x 12” in front and 14” in back  Front (F): 4 ½” x 12”h. 1 ½” hole centered 2” below top  Top (T): 4 ½” w x 6 ½”h Bottom (B): 4 ½” w x 4 ½”h. Rear (R): 6” w x 17”h Drill a ¼” nail hole ½” below the top and ½” up from the bottom Assemble Sides outside the Top and Bottom.  Notice that top will slope down toward the front.  Then assemble Front and Rear outside the box just formed.  Wood glue works well.  Caulk Top at the Rear so it doesn’t leak.  We experimented with a few different sizes for box dimensions and holes.  These sizes seemed best.
Barn Owl House For the owl house, we used the plans from UC Davis, since they are relatively nearby. ftp://ftp-fc.sc.egov.usda.gov/CA/news/Publications/wild_habitat/owl_nest.pdf The house took about half a sheet of plywood.  We built it in late 2009.  So far, no residents, but we don’t expect any until late summer.
