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.

Book Description
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.
