The eastern bluebird is a favorite migratory
songbird of birders and nonbirders alike.
The bird's
bright blue color and melodious song make it a welcome visitor to
backyards. The history of the bluebird spans a series of struggles
and successes and only recently, through active wildlife management, has its
future been considered secure. During the days of frontier settlement, the
bluebird was among the wildlife species that benefited from the
decimation of the eastern forests. The conversion of forest into pasture, orchards, and
homesites created an abundance of ideal bluebird habitat - open areas that supported
the nesting and foraging activities of the species.
Farmers unintentionally assisted bluebirds by bordering their fields with
wooden fence posts, thus supplying additional nesting sites. Combined, these
factors led to a proliferation of bluebird numbers throughout the eastern United
States through the mid-1800s. However, this situation changed in the late
nineteenth century with the introduction of the European starling and the
English house sparrow. In the twentieth century, increased use of harmful
pesticides, replacement of wooden fence posts with metal posts, clearing of
field borders and fence rows to increase cropland acreage, and a growing human
population also contributed to population reductions.
Fortunately, the favored status
of the bluebird and its acceptance of artificial nesting structures has led to
increased efforts to boost its populations to sustainable levels. Placement of
thousands of nest boxes by concerned individuals has contributed significantly
to ensuring a future for the eastern bluebird. The ongoing recovery of the
eastern bluebird is an example of how sound wildlife management practices have
been used to increase the survival success of an individual wildlife
species.
This pamphlet is designed to serve as an introduction to the habitat
requirements of the eastern bluebird and to assist in the development of a
comprehensive bluebird management plan. The success of any individual species
management plan depends on targeting the specific needs of the species and
analyzing the designated habitat areas as a whole to ensure that all required
habitat elements are present. This guide also provides recommendations for
program monitoring to document successes and to ensure that problems are
addressed as they arise. Anonymous. 1999. Eastern Bluebird (Sialia sialis). U.S. Department of Agriculture, Natural Resources Conservation Service, Madison, MS, and
