摘要

Chaco Chachalaca(Ortalis canicolis)是一种正在衰退的新热带鸟类,我们目前对其自然历史的了解非常有限。在这里,我们首次评估了被动声学监测与自动信号识别软件相结合在监测Chaco Chachalaca中的效用,描述了该物种在昼夜和季节循环模式中的发声行为,并提出了一种声学监测协议,以最大限度地减少发声活动率估计中的误差。我们在巴西潘塔纳尔的三个地点记录了一个完整的年度周期。99%的监测天数都检测到了该物种,证明这项技术是检测该物种存在的可靠方法。Chaco Chachalaca在白天和晚上都很活跃,但其昼夜活动模式在0500至0900之间达到峰值。根据声音活动的季节变化,巴西潘塔纳尔Chaco Chachalaca的繁殖季节似乎发生在旱季的最后几个月,声音活动在8月至10月之间达到峰值。我们的结果可以指导未来的调查,无论是使用传统调查还是声学调查来检测该物种的存在,还是使用被动声学监测来评估种群丰度的变化,为此,记录器应在野外放置至少九天,以获得对该物种发声活动的低误差估计。我们的研究结果表明,作为实地研究的补充工具,被动声学监测可能有助于监测其他螃蟹,这是一个有几个不愿意人类存在的濒危物种的家族。

Passive Acoustic Monitoring of Chaco Chachalaca (Ortalis canicollis) Over a Year: Vocal Activity Pattern and Monitoring Recommendations
Chaco Chachalaca (Ortalis canicollis) is a declining Neotropical bird, for which our current knowledge about its natural history is very limited. Here, we evaluated for first time the utility of passive acoustic monitoring, coupled with automated signal recognition software, to monitor the Chaco Chachalaca, described the vocal behavior of the species across the diel and seasonal cycle patterns, and proposed an acoustic monitoring protocol to minimize error in the estimation of the vocal activity rate. We recorded over a complete annual cycle at three sites in the Brazilian Pantanal. The species was detected on 99% of the monitoring days, proving that this technique is a reliable method for detecting the presence of the species. Chaco Chachalaca was vocally active throughout the day and night, but its diel activity pattern peaked between 0500 and 0900. The breeding season of Chaco Chachalaca in the Brazilian Pantanal, based on seasonal changes in vocal activity, seems to occur during the last months of the dry season, with a peak in vocal activity between August and October. Our results could guide future surveys aiming to detect the presence of the species, both using traditional or acoustic surveys, or to evaluate changes in population abundance using passive acoustic monitoring, for which recorders should be left in the field for a minimum period of nine days to obtain a low-error estimate of the vocal activity of the species. Our results suggest that passive acoustic monitoring might be useful, as a complementary tool to field studies, for monitoring other cracids, a family with several threatened species that are reluctant to human presence.
