Learn About Bluebirds
"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 areas 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., you will also find Mountain Bluebirds and Western Bluebirds. One important thing to remember when providing housing for Bluebirds is that you need to provide larger floor space and entrance holes for Western and Mountain Bluebirds. A 4 inch by 4 inch floor is adequate for Eastern Bluebirds, but a 5 inch by 5 inch floor is recommended for Mountain and Western Bluebirds. The entrance hole should be 1 1/2 inch in diameter for Eastern Bluebirds, and 1 9/16 inch for Mountain and Western Bluebirds.
