Book Description
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.
