摘要

捕食风险可能会影响鸟类的觅食行为。然而,有关家养鸟类感知捕食风险从而调整觅食行为的能力的研究却很少。在这项研究中,我们测试了在呈现雀鹰(Accipiter nisus)、家猫(Felis catus)和人类的标本和声音后,家养虎皮鹦鹉(Melopsittacus undulatus)是否感知到捕食风险,以及这是否会反过来影响它们的觅食行为。当受到视觉或声音刺激时,虎皮鹦鹉在麻雀鹰、家猫和人类处理下的进食潜伏期明显长于对照组。虎皮鹦鹉对声音刺激的反应比对视觉刺激的反应更强烈,它们对雀鹰的叫声表现出最长的进食潜伏期和最少的进食次数。此外,虎皮鹦鹉对人声的取食潜伏期和取食次数都比对雀鹰或家猫叫声的取食潜伏期和取食次数要短。我们的研究结果表明,虎皮鹦鹉可能会通过视觉或声音信号来识别捕食风险,并相应地调整其捕食行为。

Do domestic budgerigars perceive predation risk?

Do domestic budgerigars perceive predation risk?

Predation risk may affect the foraging behavior of birds. However, there has been little research on the ability of domestic birds to perceive predation risk and thus adjust their feeding behavior. In this study, we tested whether domestic budgerigars (Melopsittacus undulatus) perceived predation risk after the presentation of specimens and sounds of sparrowhawks (Accipiter nisus), domestic cats (Felis catus), and humans, and whether this in turn influenced their feeding behavior. When exposed to visual or acoustic stimuli, budgerigars showed significantly longer latency to feed under sparrowhawk, domestic cat, and human treatments than with controls. Budgerigars responded more strongly to acoustic stimuli than visual stimuli, and they showed the longest latency to feed and the least number of feeding times in response to sparrowhawk calls. Moreover, budgerigars showed shorter latency to feed and greater numbers of feeding times in response to human voices than to sparrowhawk or domestic cat calls. Our results suggest that domestic budgerigars may identify predation risk through visual or acoustic signals and adjust their feeding behavior accordingly.

期刊介绍: Animal Cognition is an interdisciplinary journal offering current research from many disciplines (ethology, behavioral ecology, animal behavior and learning, cognitive sciences, comparative psychology and evolutionary psychology) on all aspects of animal (and human) cognition in an evolutionary framework. Animal Cognition publishes original empirical and theoretical work, reviews, methods papers, short communications and correspondence on the mechanisms and evolution of biologically rooted cognitive-intellectual structures. The journal explores animal time perception and use; causality detection; innate reaction patterns and innate bases of learning; numerical competence and frequency expectancies; symbol use; communication; problem solving, animal thinking and use of tools, and the modularity of the mind.
