1. The use of detection dogs to effectively monitor bird and bat fatalities at wind farms is becoming increasingly popular. All studies to date agree that dogs outperform human searchers at finding bird and bat carcasses around wind turbines; however, it remains unclear how characteristics of the carcass and environmental conditions during the search may influence detection.
2. We investigate the effect of carcass size, vegetation characteristics and weather conditions on the probability of detecting a carcass, for both dogs and humans, using data from the monitoring program of a wind farm in Spain.
3. A generalized linear mixed model reveals a high performance of dogs (~80% detection rate), with no clear influence of any of the variables analysed. Humans, on the contrary, were markedly affected by the size of the carcass and to some extent, by the vegetation structure. Humans performed poorly at detecting small carcasses (~20% detection rate), more so in closed vegetation.
4. Synthesis and applications. Our results provide evidence that dogs perform with high success rates at detecting bird and bat carcasses of different sizes under a wide range of environmental conditions. Humans, by contrast, were very poor at detecting all but the largest carcasses in open areas. We find the use of detection dogs at wind farms to be a robust and cost‐effective alternative to using human searchers, most notably, when the focus is on the monitoring of fatalities of small, rare or inconspicuous species in closed vegetation.

使用狗和人类搜寻者影响风电场detection体检测的因素

1. 在风电场中使用检测犬有效监测鸟类和蝙蝠的死亡变得越来越普遍。迄今为止的所有研究都认为，狗在风力涡轮机周围发现鸟类和蝙蝠尸体的性能优于人类搜索者。然而，尚不清楚搜索过程中the体的特性和环境条件如何影响检测。
2. 我们使用西班牙一家风电场的监测计划中的数据，研究了size体大小，植被特征和天气状况对狗和人发现car体概率的影响。
3. 广义线性混合模型显示了狗的高性能（〜80％的检测率），而对任何已分析变量的影响均不明显。相反，人类受到the体大小的明显影响，并且在某种程度上受到植被结构的影响。人类在检测小car体方面表现不佳（约20％的检出率），在封闭的植被中则更是如此。
4. 综合与应用。我们的结果提供了证据，表明在广泛的环境条件下，狗在检测大小不同的鸟类和蝙蝠尸体方面具有很高的成功率。相比之下，人类在空旷地区除了发现最大的尸体外，都无法发现所有尸体。我们发现，在风电场使用检测犬是替代人类搜索者的强大且具有成本效益的替代方法，最值得注意的是，当重点是监视封闭植被中小的，稀有或不起眼物种的死亡时。
