Abstract
Recoveries of reward- and standard-banded American black ducks (Anas rubripes) were used to estimate band reporting rates and to investigate geographic and temporal variability in reporting rate for 1978-80. Reporting rates were higher close ( 20 km) to the parent banding site in 3 of 42 samples and were higher close to the nearest black duck banding site in 3 of 35 samples., Reporting rates were higher P 0.05) in Canada than in the Atlantic Flyway for the pre-huntIng season 1980-banded sample, but were otherwise similar among regions. Temporal differences over the duration of the study occurred, but there were no consistent trends over time. The small number of rejections suggests that there is little evidence of differences in band reporting rate by proximity to banding sites, geographic location, or over time. Thus, the best estimate of band reporting rate for black ducks is a constant 0.43. This estimate should be used with caution, because we believe that it overestimates reporting rate due to the unknown proportion of reward bands found that were not reported.
