Carolina Wren Birdhouse
The Carolina wren birdhouse has a larger entrance hole than other wren boxes. Therefore it is also open to other wrens, chickadees, nuthatches, swallows, house sparrows and more birds.
Make this box with red cedar, pine, or almost any soft wood. Use rough-cut wood on both sides so birds can grip interior and exterior surfaces.
Make the floor 4″ by 4″ (inside dimensions) and an 8″ floor to ceiling height (inside front). Cut a 1 1/2″ diameter entrance hole located 6″ above the floor (to top of hole).
Drill or cut ventilation openings in the floor and under the roof.
Attach a hinged roof for easy access to monitor and clean. Use brass shutter hooks to secure roof in closed position.
Always use corrosion resistant screws and hardware.


Extend the back wall panel beyond both top and bottom. Drill pilot holes in these long panels for mounting. Drill an extra mounting hole inside the box just under the roof. Stagger these holes so that all are not in line along a single wood grain. Holes in line with grain can weaken and cause wood to split.
Drill countersunk pilot holes in primary work pieces. Drill regular pilot holes in secondary work pieces. This reduces a tendency for wood to split. It makes for easy assembly in minutes with a power or hand held screwdriver.
Mount this nest box in forests, groves or yards on trees, posts, possibly fences or walls with partial sun and shade between four and twelve feet high. At least out of reach is best to deter the curious unless the box is well concealed. Also see the Carolina wren species page.
Remove the nest from the box in late summer or fall well after the brood rearing season is past. Store or leave the box installed and allow the box to winter over clean and dry. It might be used as a warmer by various birds.

Chickadees, Titmice and Nuthatches may also use this nest box.
