Tips to Attracting Bluebirds to Your Backyard!
"Somewhere over the rainbow, Bluebirds Fly."
That famous lyric from the "Wizard of Oz" helped immortalize the beautiful Bluebird. Since early colonial times, people have loved Bluebirds because of their beauty, their feeding in open area around houses and farms, and their endearing habit of readily nesting in man-made boxes.
In the U.S. there are three different types of Bluebirds.
The Eastern Bluebird that occurs east of the Rockies is by far the most numerous. Across the Western one-third of the U.S.A. you will also find Mountain Bluebirds and Western Bluebirds. One important thing to remember when providing housing for Bluebirds, you need to provide larger floor space and entrance holes in diameter for Western and Mountain Bluebirds. A 4" by 4" floor is recommended for Mountain and Western Bluebirds. The entrance hole should be 1 ½" in diameter for Eastern Bluebirds, and 1 9/16" for Mountain and Western Bluebirds.
A Bluebird's primary diet is insects and fruit. Planting native plants like American Bittersweet is a great way to attract and help Bluebirds. Another super way to attract and help Bluebirds is by feeding mealworms. At 50.4% protein, they are an excellent nutrition source.
You can start feeding mealworms in a cup or pan, but because many birds like them and will eat you out of house and home, most people graduate to a Bluebird Feeder. In a Bluebird Feeder, the bird has to go through an entrance hole to find the worms and few birds besides the Bluebird will do so. You might spend weeks trying different presentations of worms before Bluebirds learn to dine regularly, but the results are worth it, as Bluebirds are delightfully trainable, even to the point of responding to whistles and other calls when your feeder is refilled.
All Bluebirds are cavity nesters. Bluebird populations once common in rural and suburban areas, declined by as much as 90% from 1920-1970. The decline was due to two things: The loss of nesting habitats, such as tree holes, rotted out fence posts and old orchards; and the introduction of the Starling and House Sparrow in the last half of the 1800's. These two species, introduced from Europe, competed heavily with the Bluebird for existing nesting cavities. Utilization of a sparrow trap is often critical to Bluebird breeding success.
Now you too can make a contribution to conserving these beautiful birds by putting up nest boxes in appropriate habitat. The key to attracting Bluebirds to nest in your yard is having plenty of potential nesting locations, food and water. Bluebirds do prefer more "open area" so if your yard is heavily wooded you'll enjoy many other nesting birds, but probably not Bluebirds.
The female will lay four to five light blue eggs that will take thirteen to fifteen days to hatch. The mail brings food to his mate and the young during the critical first few days of feeding. They act like tiny hawks, in their slumped hunting position, waiting patiently for an insect or beetle to show itself. It then pounces on it and brings the food back to the nest. Providing a T-shaped perching cross ten to twenty yards in front of the nest box can sometimes help attract Bluebirds.
