Abstract:
There has been a decline in quail and seventeen other bird species associated with farming and weedy, grassy, brushy habitats in North Carolina and other Southeastern states. Bromley, Bill Palmer, and Marc Puckett investigated whether pesticides and drainage ditch management were possible causes. Results are reported. Also included is a set of nine questions, which the author says will be a large, complex research project seeking to account for the decline, and which he hopes will be answered by the end of the century.

Abstract:
One of the state's noblest traditions--quail hunting--is in danger of extinction. Prior to the 1970s, more than 175,000 hunters came to the state and harvested between 2.2 and 2.8 million quail. During the 1995 season only 28,000 hunters harvested 225,000 quail. Jones discusses reasons for the decline and whether it can be reversed. In the state quail are declining at 6.2 percent per year from 1982 to 1991.

Abstract:
The tree swallow (Tachycineta bicolor) has expanded its range throughout North Carolina and the southeast, despite its reputation has a generally sporadic or irregular breeder. Research shows that land clearing, impoundments and other land use patterns, the reintroduction of beavers, and the use of bluebird boxes by swallows as nest sites appear to have facilitated the expansion.

Abstract:
Before the 1970s, quail were abundant in the Southeast, but the population has rapidly declined since then. A major study seeks to answer why this has happened. Changing land use, predation, natural fluctuations, and control by man of naturally occurring fires are seen as contributing factors in the decline.

Abstract:
Many species of birds are endangered because of destruction of their habitats. Warren B. King, chairman of the U.S. Section of the International Council for Bird Preservation, cites the Mauritius parakeet, Spanish imperial eagle, and imperial woodpecker as examples of near-extinct bird populations.
