Available in PDF, EPUB and Kindle. Book excerpt: This report presents the recovery distributions of 10 species of game ducks banded as flightless young on the breeding grounds. Conclusions are based on 20,15 direct or first year band recoveries, 9,272 of which are mallards. The recovery distributions of these ducks by State and Flyway, or country, of recovery from breeding ground aerial survey strata or State banding are presented. In addition, mallard recoveries from bandings grouped by geographical region are presented to show distribution variations attributable to region, year of banding, sex, first year versus later years of recovery, weather, etc. Recovery rates of mallards banded as flightless young and the affects of various factors on recovery rates are discussed.

Book excerpt: This paper brings together the results of black-duck banding throughout North America, and attempts to show, for the benefit of sportsman and administrator alike, where the birds of Barnegat Bay, St. Clair Flats [St. Clair Flats Wildlife Area, Michigan], or any other important hunting area come from. The banding may shed some light also on the questions when do the various groups of birds move and when might they be expected to arrive from certain regions to the north under conditions existing today.

Available in PDF, EPUB and Kindle. Book excerpt: Of 37,000 reports of mourning dove band recoveries in the files of the Migratory Bird Populations Station on October 30, 1967, 1,120 came from Mexico, and half of those were from Jalisco and Michoacan, both in west-central Mexico; Jalisco alone accounted for nearly a third. Few recoveries were reported from the area between the U.S. border and mid-Mexico. Generally, lower proportions of total recoveries were reported from Mexico under the current pre-hunting season banding program for flying birds than were reported from the nestling dove banding program of the 1950's. Bandings in the northern U.S. States produced proportionally more recoveries than bandings in the southern U.S. States. Doves banded over diverse areas of the United States were harvested in common migration with wintering areas in Mexico. Possible explanations of the heterogeneous distribution of recoveries throughout Mexico are discussed. Of the banded birds for which "how obtained" was known, 83.5 percent were reported as shot (or killed) and only 3.2 percent reported as captured or trapped. Among 658 persons who gave their name and residence when they reported bands, 95.7 percent had typically Spanish surnames and were residents of Mexico. Depending upon actual banding reporting rates and the representativeness of the banding data analyzed, the Mexican dove harvest may equal or exceed harvests in leading U.S. States. Factors influencing band reporting rates must be resolved before Mexico's importance as a harvest area can be accurately determined.

Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this paper is to discuss the role of banding data in migratory game bird management. The procedures followed in analyzing these data and the assumptions made are also outlined. This information is desired not only to better understand and justify expensive banding programs, but also to provide guidance to those wishing to analyze banding data. This understanding is essential, not only to effectively use the resulting data, but also to make correct decisions in the field while banding. A realization of how banding data are used emphasizes the importance of many details, such as the accurate age and sex determinations in the field and the correct reporting of this information on banding schedules.
