本文报道了一项野外实验，旨在调查空中捕食者的初步发现和野生笑鸽作为不同大小群体的成员取食时的逃逸反应。结果表明，在一定的范围内，大群群比小群群有更高的概率发现接近的捕食者。讨论的重点是炎热干旱国家中鸽子的群居习性，重点是在水坑前成群。
The paper reports on a field experiment designed to investigate the initial detection of an aerial predator and the escape response by wild laughing dovesStreptopelia senegalensiswhile feeding as members of flocks of different size. Results indicate that, within certain limits, a large flock has a higher probability of detecting an approaching predator than a small flock. Discussion centres on the gregarious habits of doves in hot arid country, focusing on flocking at water holes.
