Book excerpt: 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.

Download or read book The Technical Literature on the American Woodcock, 1927-1978 written by Thomas J. Dwyer and published by . This book was released on 1979 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 excerpt: 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 1971 singing-ground survey showed declibnes in the breeding population index of 9.7% in the Atlantic Region, 7.2% of the Central Region, and 8.3% increase rangewide. The wing-collection survey for the 1970-71 season suggested the greatest 1-year change in productivity in the history of the survey -- a 25% increase. Average daily bag per hunter was unchanged from the previous year, while the average season bag showed a slight increase. There is evidence that the woodcock harvest and number of hunters participating have increased substantially since 1964, with the U.S. harvest exceeding 1.3 million birds. Woodcock research is increasing, with present emphasis on more banding on breeding grounds. Limited band recoveries to date suggest little interchange between Atlantic Region and Central Region breeding populations.
