Download or read book Trends in Harvest of Migratory Game Birds Other Than Waterfowl 1964 65 to 1968 69 written by Elwood Martin and published by . This book was released on 1971 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Responses to questions pertaining to harvest of migratory game birds other than waterfowl and coots included in the annual mail questionnaire survey of waterfowl hunters are summarized for the hunting seasons of 1964-65 through 1968-69. Results show an upward trend in hunting and harvest of other migratory game birds. This trend is correlated with an increase in duck stamp sales since 1965-66 but in general the increase in other migratory game bird hunting is greater. Analysis of these data demonstrates the weaknesses inherent in using a sampling fram based on duck stamp buyers to assess harvest and hunting of other migratory game birds.
Download or read book Hunting and Harvest Trends for Migratory Game Birds Other Than Waterfowl 1964 76 written by Elwood Martin and published by . This book was released on 1979 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hunting activity and harvest estimates for 10 species or groups of migratory game birds other than waterfowl, based on data collected for 13 seasons (1964-76) in the Annual Questionnaire Survey of U.S. Waterfowl Hunters, are presented. A number of long-term trends were noted. High correlations obtained between certain results in the survey and the results of independent surveys are discussed. The inescapable conclusion is that, although this survey of waterfowl hunters provides valuable data on the subject, a better sampling frame (or frames) for measuring the activity and success of all hunters of migratory game birds other than waterfowl is needed to meet the high standards now being set for the management of this valuable resource.

Book excerpt: U.S. mourning dove population indexes increased by 4% from 1969 to 1970 in the Eastern Management Unit, but declined 2% in the Central Management Unit and 11% in the Western Management Unit. The changes were below the 10-year means, 1960-69, by 3% in the Eastern Unit, 15% in the Central, and 27% in the Western. Regression analyses of the call-count data for 1960-70 indicate a statistically significant downward trend in dove breeding populations in all management units; mean rates of decline were 1% a year in the Eastern Unit, 3% a year in the Central, and 4% in the Western

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.

Available in PDF, EPUB and Kindle. Book excerpt: 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.
