Where you choose to place the box is as
important as how the box is designed. Bluebirds are birds of open areas. They
rarely nest in wooded areas, but will nest in clearings. Open areas with scattered
trees are best. Open fields are suitable if there are posts or wires for
perching. Look for any area where the vegetation is kept short by mowing, or grazing such
as parks, campgrounds, pastures, large lawns, cemeteries, golf courses, and abandoned
orchards. Generally, bluebirds nest only in rural areas and the very outer edges of
suburban developments. Proper placement of your nesting box(es) can encourage
bluebirds and discourage other competing birds and predators.
recommend that nesting boxes be mounted on 6 to 6-1/2 feet pipe. The boxes should be
mounted 4 to 5 feet from the ground. It is recommended that they be placed 100 yards
apart because bluebirds establish a territory during the nesting season and a nesting pair
will not allow other bluebirds to enter their territory.
Tree Swallows are the birds
most often found in bluebird boxes. To maximize your chances of attracting
bluebirds amidst competition from swallows, we recommend placing two boxes 5-8 feet apart.
Swallows will exclude another pair of swallows from nesting this close.
Swallows only defend their nest site itself. This leaves the adjacent box open to
House Wrens like more bushy
areas. To avoid competition with the house wren, place the bluebird nesting box in
more open areas at 50 feet or more away from brush and woods.
Face the box towards a tree, shrub, or pole,
so the young can fly toward it. Your nesting box should be put up and ready for use
by the end of March if possible. If they are put up later than this time, they still
should be attractive to bluebirds who are raising their second or third broods. Be
patient. It may take several seasons for bluebirds to find your box. Remember
