Deaths occurred between 21 and 158 days after confinement and were associated with infections of </span><i>Aspergillus fumigatus</i><span>, </span><i>Escherichia coli</i><span>, </span><i>Staphylococcus</i><span> sp., </span><i>Streptococcus</i><span> sp., </span><i>Klebsiella</i><span> sp., </span><i>Enterobacter</i><span> sp., and </span><i>Plasmodium</i><span> sp. Infection and mortality was believed to result from reduced resistance associated with confinement. Fourteen canvasbacks released onto large ponds survived throughout the period during which the penned birds died.</span></p></div>
