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:
“We have been God-like in our planned breeding of our domesticated plants and animals, but we have been rabbit-like in our unplanned breeding of ourselves.”
—A.J. (Arnold Joseph)
“They tell us sometimes that if we had only kept quiet, all these desirable things would have come about of themselves. I am reminded of the Greek clown who, having seen an archer bring down a flying bird, remarked, sagely: “You might have saved your arrow, for the bird would anyway have been killed by the fall.””
—Elizabeth Cady Stanton (1815–1902)
“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)
