摘要

战斗或逃跑的决定(即参与或逃避相互作用)是动物最重要的决定之一,发生在许多不同的生态环境中,并决定了可能导致受伤甚至死亡的激烈相遇的发生。南田凫Vanellus chilensis是南美洲最常见的鸟类之一,生活在天然草原上,但也经常出现在农村和城市地区。该物种以其典型的发声方式和侵略和领土的模式而闻名,被认为是夸张的,造成了对该物种的文化偏见。为了更好地理解物种间的竞争相互作用过程,我们使用一般线性模型验证了个体特征、环境特征和对手特征对与相互作用相关的五个不同反应变量的影响:警戒行为显示时间、攻击和逃避概率、相互作用总持续时间和每次相互作用的行为多样性指数(BDI)。尽管模型显示,对于每个响应变量,预测因子具有不同的重要性和权重,但可以注意到,年龄、繁殖状态和月份等个体特征直接影响逃避或攻击的概率,而对手物种和距离更好地解释了与相互作用相关的其他变量。结果还表明,在繁殖季节,南田凫对入侵者的反应强度和敏感性都有所增强,表现出与其他鸟类一样的自我保护和保护后代之间的权衡。

Individual features influence the choice to attack in the southern lapwing Vanellus chilensis, but the opponent type dictates how the interaction goes

The fight or flight decision (i.e., engage in or evade from an interaction) is one of the most important for animals, occurring in many different ecological contexts and dictating the occurrence of agonistic encounters that could lead to injuries or even death. The southern lapwing Vanellus chilensis is one of the most conspicuous bird species from South America, living in the natural grasslands but frequently found in rural and urban area. The species is known by its typical vocalization and its patterns of aggression and territoriality, considered exaggerated, creating a cultural prejudice towards the species. To better understand the agonistic interaction process in the species, we used general linear models to verify the influence of individual characteristics, environmental characteristics, and opponent features on five different response variables related to the interactions: the time of alert behavior display, probability to attack and evade, total duration of the interaction, and the Behavioral Diversity Index (BDI) of each interaction. Despite the models showing that for each response variables the predictors had different importance and weights, it was possible to note that individual features like age, breeding status, and month impact directly the probability to evade or attack, while the opponent species and distance better explained the other variables related to the interaction. The results also showed that the southern lapwings increase the intensity of responses and sensibility to intruder during the breeding season, displaying a trade-off between self-preservation and the protection of the offspring that is present in other bird species.

期刊介绍: acta ethologica publishes empirical and theoretical research papers, short communications, commentaries, reviews and book reviews as well as methods papers in the field of ethology and related disciplines, with a strong concentration on the behavior biology of humans and other animals. The journal places special emphasis on studies integrating proximate (mechanisms, development) and ultimate (function, evolution) levels in the analysis of behavior. Aspects of particular interest include: adaptive plasticity of behavior, inter-individual and geographic variations in behavior, mechanisms underlying behavior, evolutionary processes and functions of behavior, and many other topics. acta ethologica is an official journal of ISPA, CRL and the Portuguese Ethological Society (SPE)
