在丛林乌鸦（乌鸦macrorhynchos）的脚使用行为的偏侧性进行了研究。侧化的一致性也验证了两种不同的行为进行比较。一个是抓鸟嘴，另一个是拿食物。在13名受试者中，11名受试者的抓喙和12名受试者中的10名受试者的食物保持中发现了显著的偏侧性。足使用偏侧性的偏倚在足受试者中并不常见，表明没有人群水平的偏倚。然而，一个显着数量的足科目（10 12）谁在这两种行为进行了测试，表现出一致的偏侧性，无论行为的差异。这些结果表明，丛林乌鸦有很强的个人水平的侧化在脚的使用行为。(c)2005 Elsevier B.V.保留所有权利。
Laterality of foot-use behaviour was examined in jungle crows (Corvus macrorhynchos). Consistency of laterality was also verified in comparison with two different behaviours. One was beak-scratching, and another was food-holding. Significant bias of foot-use laterality was found in I I of 13 tested subjects for beak-scratching and in 10 of 12 tested subjects for food-holding. Bias of foot-use laterality was not common among footed subjects, suggesting no population-level bias. However, a significant number of footed subjects (10 of 12) who were tested in both behaviours showed consistent laterality irrespective of behavioural differences. These results suggest that jungle crows have strong individual-level laterality in foot-use behaviour. (c) 2005 Elsevier B.V. All rights reserved.
