[email protected] 21 22 Running head: GIZZARDS AND GRITS OF WILD CRANES 23 2 24 ABSTRACT. We analyzed the gizzards, and grits retained in the gizzards of 41 25 cranes that migrated to the Izumi Plain during the winter of 2015/2016 and died 26 there, either due to accident or disease. These included 31 Hooded Cranes (Grus 27 monacha) and 10 White-naped Cranes (G. vipio). We determined body weight, 28 gizzard weight, total grit weight and number per gizzard, and size, shape, and 29 surface roundness of the grits. Average gizzard weights were 92.4 g for Hooded 30 Cranes and 97.1 g for White-naped Cranes, and gizzard weight positively correlated 31 with body weight in both species.
