Which Way Do You Face a Birdhouse?

Is there a particular direction I'm suppose to face my new bluebird house? Julie in Mason, MI

My first response for the placement of a bird house was the same advice I give in the placement of bird feeders; put the houses where you can view them. After years of customer feedback I still give that advice but add that if possible the entrance hole should face east or southeast for the most success.

In Mid-Michigan Eastern Bluebirds like to nest in fields, meadows, orchards, farm fields, large lawns, and golf courses. Their houses should be mounted on our Wild Birds Unlimited APS birdhouse pole or a fence post approximately five feet above the ground. If possible, face the house away from prevailing winds and facing towards a tree or shrub and 100 feet from the house. Trees and shrubs provide a perching area for the bluebirds to hunt bugs and a landing spot for the young bluebirds when they first leave the house. Eastern Bluebird houses should be spaced at least 100 to 150 yards apart.

I did a little investigating and found a report to back up our customers' theory that birds have a preference in the direction of their house. Cornell Lab of Ornithology has collected research by citizen scientists across the U.S. to reveal that the Eastern Bluebirds will nest in a bird house that faces in any direction. In the northern states like Michigan, however, the birds prefer the early morning sun coming in the front of the house as it faces the east.

The studies showed: "Overall, it is clear that nest boxes facing in easterly directions fledged on average more young than boxes facing in other directions. Our data, therefore, suggest there is a benefit to breeding in east-facing nest boxes at northern latitudes, where night temperatures tend to be colder. No benefit, however, could be detected farther south." [1]

Cornell is still collecting information on nesting. Anyone can monitor nests - it's a rewarding way to spend time outdoors and participate in science. To learn more go to NestWatch a nest-monitoring project developed by the Cornell Lab of Ornithology in collaboration with the Smithsonian Migratory Bird Center, and funded by the National Science Foundation.

  1. I lived in Northern Virginia. Fairfax County gardening zone 7. When I first attempted the placement of the box it was in the direction facing the front of my home. The direction was South. I watched for a couple of years, while the newly wed couples would house hunt. He would bring her to the property and encourage her to check it out. She did on several occasions. In , out, in out. Then to both of our chagrins the answer was an emphatic , NO! Eventually I placed the box , facing the sunrise. East. Major success! Not only did they come,( for we built it )but they even ousted other birds. Killing their offspring. Not the best experience, but it meant this was a VERY desirable property! Since that positioning , I tended to three, yes three clutches a year! I had counted at least 24 clutches of 4 birds per clutch ! What a success it was. I enjoyed watching them for years, and even had the opportunity to open the box and allow my small girl's to gaze upon the wonder of life.
