    A preliminary investigation into effects of flipper banding on African penguins spheniscus demersus
    (2007) Hampton, Shannon; Ryan, Peter G; Underhill, Les; Petersen, Samantha
    Much of what is known about penguin movements and life history traits, including their population dynamics, and particularly the rehabilitation success after oil spills results from information derived from marking birds with flipper bands. However, flipper bands may negatively impact the welfare of penguins. While studies on the impact of banding have been undertaken for several penguin species, no such study has investigated the exclusive effect of banding on African Penguins Spheniscus demersus. I do so by comparing the difference in yearly return rates as well as foraging trip durations of 100 individuals injected with a subcutaneous transponder only, and 100 that have both transponders and a stainless steel flipper band.
