Book Description
Groups of data are organized by flyways, from Pacific to Atlantic, with appendixes of tables to correspond. Individuals or organizations that submitted a report have been credited. Although many of the narrative statements have been briefed, and a few tables deleted or shortened if they contained data submitted previously or in another form, the essential information from each report has been retained to the greatest extent possible.

Book Description
The estimated continental woodcock harvest exceeded 1.5 million birds during the 1973-1974 hunting season. Wing-collection data for 1973-74 indicated that productivity increased during the previous spring by 15% rangewide, % in the Atlantic Region, and 21% in the Central Region. Daily and seasonal hunting success was also greater by 8.6% and 10.0% respectively. The 1974 breeding population index increased increased 6.5% rangewide, 2.4% in the Atlantic Region, and 10.0% in the Central Region. Indices from 1964-74 suggested a declining breeding population in the Central Region. Recoveries of 2,950 banded woodcock indicate the existence of two relatively distinct populations. More than 94% of the recoveries were made in the Region of banding.

Book Description
Information on the current status and population trends of the American woodcock is provided by annual singing-ground surveys over much of the species' breeding range and a wing-collection survey in the eastern United States. the 1970 singing-ground survey showed no change in the breeding population index for the Eastern region, a 3.12% increase for the Western region, and a 2.11% increase rangewide. This index is based on 752 comparable survey routes, all randomly selected, 35% more than the 568 routes used in 1969. The wing-collection survey for the 1969-70 season suggested a decline of 7.03% in productivity the previous summer, a slight decline in the average daily bag per hunter, and a sharper drop of 11.1% in the average seasonal bag. There is evidence that the woodcock harvest and the number of hunters participating increased over previous years, with the 1969-70 harvest exceeding 1.1 million birds. Woodcock research is increasing, with the present emphasis directed to banding on breeding grounds.

Book Description
In this bibliography we have attempted to assemble the major portion of the technical literature on the American woodcock (Philohela minor). Included are scientific references published between 1927 and 1978. We chose 1927 as the cutoff date for early literature because of the importance of Arthur Cleveland Bent's work in 1927, and because most articles before 1927 are descriptive and do not add appreciably to the scientific literature on the species. An excellent listing of the early literature may be found in the 1936 monograph by Olin Sewall Pettingill, Jr. No previously published bibliography devoted solely to woodcock is available. References are listed alphabetically by author beginning on page 1. Following each reference is a number(s) that corresponds to one of the 22 subject headings listed on page iii.

Book Description
A relatively few species account for most of this mortality but continue to maintain large, harvestable populations, suggesting that the numbers of most bird species are essentially unaffected by the human activities discussed. Other activities of man that do not necessarily result in the death of birds but rather reduce reproductive potential are more likely to have long-term effects on avian populations.
