摘要

大多数鸟类的物候特征都与当地气候条件密切相关,即使在气候季节性较弱的热带栖息地也是如此。为了更好地了解热带留鸟的物候,以及同一地点不同物种之间的物候差异,我们在新加坡的四个录音站连续收集了两年约 7 万小时的录音,并使用九个定制的机器学习分类器来确定九种留鸟的发声物候。我们发现一些物种的歌唱活动具有明显的季节性,而其他物种则没有。原生森林物种的歌唱是季节性的。与此相反,过去几十年才在新加坡有繁殖种群的物种,其鸣唱活动似乎全年都是季节性的或不可预测的。过去 100 年的城市化和栖息地改造改变了新加坡的物种组成,这似乎影响了鸟类群落的物候动态。目前还不清楚是什么导致了这两类物种在物候学上的差异,但这可能是由于偏好食物的季节性可用性不同,也可能是由于新建立的种群可能需要几十年的时间来适应当地的环境条件。我们的研究结果突显了人为生境改造除了改变物种群落外,还可能扰乱热带地区物候周期的方式。

Acoustic phenology of tropical resident birds differs between native forest species and parkland colonizer species
Most birds are characterized by a seasonal phenology closely adapted to local climatic conditions, even in tropical habitats where climatic seasonality is slight. In order to better understand the phenologies of resident tropical birds, and how phenology may differ among species at the same site, we used ~70 000 hours of audio recordings collected continuously for two years at four recording stations in Singapore and nine custom‐made machine learning classifiers to determine the vocal phenology of a panel of nine resident bird species. We detected distinct seasonality in vocal activity in some species but not others. Native forest species sang seasonally. In contrast, species which have had breeding populations in Singapore only for the last few decades exhibited seemingly aseasonal or unpredictable song activity throughout the year. Urbanization and habitat modification over the last 100 years have altered the composition of species in Singapore, which appears to have influenced phenological dynamics in the avian community. It is unclear what is driving the differences in phenology between these two groups of species, but it may be due to either differences in seasonal availability of preferred foods, or because newly established populations may require decades to adjust to local environmental conditions. Our results highlight the ways that anthropogenic habitat modification may disrupt phenological cycles in tropical regions in addition to altering the species community.
