A breeding bird survey monitors the status and trends of bird populations. Data from the survey are an important source for the range maps found in field guides. The North American Breeding Bird Survey is a joint project of the United States Geological Survey (USGS) and the Canadian Wildlife Service. The UK Breeding Bird Survey is administered by the British Trust for Ornithology, the Joint Nature Conservation Committee, and the Royal Society for the Protection of Birds.
The results of the BBS are valuable in evaluating the increasing and decreasing range of bird population which can be a key point to bird conservation. The BBS was designed to provide a continent-wide perspective of population change.

Famous quotes containing the words breeding, bird and/or survey:
“Not everyone knows how to be silent or to leave in good time. It happens that even people of good breeding fail to notice that their presence provokes in the weary or preoccupied host a feeling akin to hatred, and that this feeling is tensely concealed and covered up with lies.”
—Anton Pavlovich Chekhov (1860–1904)
“With the holders holding my hand nearing the call of the bird,
Comrades mine and I in the midst, and their memory ever to keep, for the dead I loved so well,
For the sweetest, wisest soul of all my days and
lands—and this for his dear sake,
Lilac and star and bird twined with the chant of my soul,
There in the fragrant pines and the cedars dusk and dim.”
—Walt Whitman (1819–1892)
“By contrast with history, evolution is an unconscious process. Another, and perhaps a better way of putting it would be to say that evolution is a natural process, history a human one.... Insofar as we treat man as a part of nature—for instance in a biological survey of evolution—we are precisely not treating him as a historical being. As a historically developing being, he is set over against nature, both as a knower and as a doer.”
—Owen Barfield (b. 1898)
