The opening is an oblong 7/8" high by 2" wide. This can be made by drilling two 7/8" holes and using a keyhole saw to cut out the extra wood in the middle. The bottom of the entrance should be 3" from the bottom of the house. This entrance shape keeps out House Sparrows while allowing Violet-green Swallows in. The design of this house is by Hubert Prescott, taken from a sheet published by the Black Hills Audubon Society.

An alternative opening is an elongated diamond 7/8" high and 3 1/2" wide designed by Gene Derig of Anacortes, WA. I had a pair of Black-capped Chicadees accept the diamond opening version of this house one year, even though it was suspended under the eave of the roof!
