Cavity nesting birds will thank you since development means fewer suitable nesting places for them. With this one simple addition, you can help support the populations of native birds.
But it's not only the birds who'll benefit. You'll enjoy the richness of watching the birds nest and produce young. A simple wren house in our yard was a wonderful source of entertainment when my son was a toddler. Each year we waited to hear the song of the young, the sign that the new brood had hatched. Simple pleasures are always the best. A Nest View Bird House wouldn've been even better since we could have followed the action inside.
Gardening-for-Wildlife.com suggests that fall or early winter is the best time to put up a new birdhouse since cavity nesters may begin house hunting by mid-winter.
For more information on the benefits and criteria for birdhouses, see the following articles by the Alabama Wildbird Conservation Assoc.: A Birdhouse in Every Garden and Birdhouses and the Birds That Use Them.
This Christmas, think about giving a gift to the birds.
