Book Description
Information on the current status and population trends of the American woodcock is provided by a singing-ground survey conducted over much of the species' breeding range and a wing-collection survey in the eastern United States. the 1969 singing-ground survey, in which 90 percent of the comparable routes were randomly located, indicated an increase in the breeding population of 4.22% in the Eastern region, 12.14% in the Western region, and 8.82% on a rangewide basis. The 1968-69 wing-collection survey suggested an increase in productivity of 5.35%, the first noticeable improvement since 1961-62. Daily harvest per hunter increased slightly in 1968-69 for the second consecutive year, but the seasonal harvest per hunter did not change. Although the sampling frame is inadequate the best available evidences suggests that the harvest of woodcock is increasing because more hunters are participating. The 1968-69 harvest in the United States approximated 1 million birds. The 1968 harvest in Canada was approximately 100,000 birds. There is some evidence that middle-latitude States could realize more recreational benefits from woodcock by adjusting their season to coincide with the peaks of woodcock migration. Woodcock research has materially increased the past 2 years, chiefly through the Accelerated Research program for Migratory Upland Game Birds.

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.

Pages : 48
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.

Pages : 542
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.
