濒危丹顶鹤是最具文化标志性、最受野生动物游客追捧的物种之一。在这里，我们调查了游客的存在如何影响鹤在碱蓬湿地觅食的警惕行为。黄河三角洲莎草/芦荟栖息地，中国。我们发现，在野生动物游客的存在下，鹤的警戒频率和持续时间都显着增加。鹤类警觉频率的增加只发生在多角鹤中。两种生境的警戒时间没有显着差异。在两个栖息地，鹤的警戒性随着距离野生动物游客的增加而下降，最小的干扰距离触发了300 m处的鹤的高度警惕。野生动物游客的存在可能是对觅食鹤的一种干扰，但与栖息地有关。塔勒普。澳大利亚的植被主要是对鹤的视觉障碍，导致它们增加警惕行为的频率。我们的发现对保护在黄河三角洲越冬的迁徙丹顶鹤种群具有重要意义，并有助于为游客管理提供信息。
The Endangered Red-crowned Crane (Grus japonensis) is one of the most culturally iconic and sought-after species by wildlife tourists. Here we investigate how the presence of tourists influence the vigilance behaviour of cranes foraging inSuaeda salsasalt marshes andS. salsa/Phragmites australismosaic habitat in the Yellow River Delta, China. We found that both the frequency and duration of crane vigilance significantly increased in the presence of wildlife tourists. Increased frequency in crane vigilance only occurred in the much tallerS. salsa/P. australismosaic vegetation whereas the duration of vigilance showed no significant difference between the two habitats. Crane vigilance declined with increasing distance from wildlife tourists in the two habitats, with a minimum distance of disturbance triggering a high degree of vigilance by cranes identified at 300 m. The presence of wildlife tourists may represent a form of disturbance to foraging cranes but is habitat dependent. TallerP. australisvegetation serves primarily as a visual obstruction for cranes, causing them to increase the frequency of vigilance behaviour. Our findings have important implications for the conservation of the migratory red-crowned crane population that winters in the Yellow River Delta and can help inform visitor management.
