胶囊大蟾蜍奥蒂斯迟达获得警惕的好处，从增加组的大小：他们表现出组的大小和个人扫描的百分比之间的负相关性，和组的大小和时间与至少一个人扫描的百分比之间的正相关性。警惕性和组的大小之间的关系是独立的干扰水平，但个人的警惕性较高，更接近一条道路。更大的群体规模和提供连续的高质量栖息地远离干扰，使大水牛，以减少个人的警惕性，从而可能增加投资的喂养时间和他们的生存。
Capsule Great Bustards Otis tarda gained vigilance benefits from increasing group size: they showed a negative correlation between group size and the percentage of individuals scanning, and a positive correlation between group size and the percentage of time with at least one individual scanning. The relationship between vigilance and group size was independent of level of disturbance but individual vigilance was higher closer to a road. Higher group size and provision of continuous areas of high-quality habitat away from disturbance allows Great Bustards to reduce individual vigilance and so potentially increase investment in feeding time and their survival.
