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.

The Technical Literature on the American Woodcock, 1927-1978
Author: Thomas J. Dwyer
Publisher:
ISBN:
Category : Woodcock
Languages : en
Pages : 56
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.
