| If building a birdhouse for use by birds, versus purely for ornamental use, you should try to incorporate the following features: -
The roof should overhang the sides to prevent rain from entering. -
The roof should overhang the entrance to give some protection from sun, rain, hawks, and other predators. -
The entrance should be placed high on the front panel to keep the nestlings or eggs beyond the grasp of predators. Note: entrance hole should be at proper height above the floor as recommended for species desired. -
Use saw cuts, chisel cuts or 'rough-up' wood directly below the entrance hole, (inside and outside) in order to allow the adults and fledglings to get a toe hold. -
A 1/4" gap above the front panel allows for ventilation by convection current during hot weather. This is especially important when youngsters tend to block the entrance hole during the week prior to fledging. -
The floor should have adequate drainage. Drilled vent holes tend to plug up with nesting litter. Cutting a notch from each corner of the floor is more efficient. -
Vent holes on the side walls should be drilled at an upward angle to shed rain while still allowing cross ventilation. -
Ensure that a side panel, front panel or the roof can be opened. This allows for easy access when cleaning or checking the nestlings. |  The above photo was taken by Diane Pascal of Nepean. If you look closely you will notice that what at first glance appears to be a cute birdhouse has actually been taken over by paper wasps. They made their nest inside the house then began wrapping it from the top outside! Special thanks to Ministry of Natural Resources Conservation Officer Randy Marinelli for his birdhouse tips! |
