Hematologic parameters were studied in giant Canada geese (Branta canadensis maxima), mallard ducks (Anas platyrhynchos platyrhynchos) and various species of diving ducks at seasinal intervals throughout the year. Highest values for packed cell volume, hemoglobin content and erythrocyte counts were found in the winter and pre-nesting periods. Mean corpuscular volume and mean corpuscular hemoglobin varied inversely with these values.
在全年不同季节对加拿大黑雁（Branta canadensis maxima）、绿头鸭（Anas platyrhynchos platyrhynchos）以及各种潜水鸭的血液学参数进行了研究。红细胞压积、血红蛋白含量和红细胞计数的最高值出现在冬季和筑巢前期。平均红细胞体积和平均红细胞血红蛋白含量与这些值呈相反变化。
