BUILD A BIRD HOUSE

(From USGS N Prairie Wildlife Research Center)

For House Wrens * , Black- capped Chickadee * ,  also White-breasted Nuthatch, but NOTE that for the Nuthatch an entrance hole of 1 1/4" is needed, so House sparrows would be likely to use it!

 

Use one nail or screw at bottom to hold door closed.  Note: Entrance hole diameter is 1 1/8".

Lumber: One four foot long  1"x6" board. Board layout for cutting:

Back 11”

Front  8”   O

Roof 8 ¼”

Side 8”

Side 8”

Floor 4”

*Please NOTE that any birdhouse entrance 1 1/4 inches in diameter or larger will admit house sparrows, which are very aggressive nesters likely to keep other birds out!  All wren and chickadee nest boxes should have an entrance hole of 1 1/8 inches in diameter.
