Habitat spatial distribution, seasonal variation, and activity patterns influence changes in vertebrate assemblages over time. Terrestrial birds play major roles in the dynamics of tropical forests, but there are few effective methods to study these species due to their cryptic coloration and elusive behavior. We used camera‐trap data collected during 16 mo (February 2017–June 2018) to describe the terrestrial avifauna in southeastern Peru, assess to what extent the composition of terrestrial avifauna changes among seasons and across two major habitats (terra firme and floodplain forests), and determine daily activity patterns of terrestrial birds. We used overlap analyses to examine temporal co‐occurrence between ecologically similar and sympatric species. Camera traps recorded 16 species, including eight species in the family Tinamidae. Capture rates were highest for Pale‐winged Trumpeters (Psophia leucoptera; Psophiidae) and Gray‐fronted Doves (Leptolila rufaxilla; Columbidae). Species composition did not differ between habitats or seasons, and capture rates between habitats only differed for White‐throated Tinamous (Tinamus guttatus). Overlaps of activity patterns were high between ecologically similar species and species found in terra firme habitats (White‐throated Tinamous and Cinereous Tinamous, Crypturellus cinereus) and in both habitat types (Pale‐winged Trumpeters and Gray‐fronted Doves). Low numbers of captures of possibly locally rare or less abundant species hindered a complete analysis of spatial and seasonal patterns of terrestrial bird assemblages. We suggest a greater sampling effort and greater spatial replication to better understand the spatial and seasonal dynamics of the terrestrial avifauna. Further studies that assess the mechanisms that allow the coexistence of sympatric tinamous would be valuable, both in our study area and elsewhere. The use of camera traps in long‐term monitoring projects proved to be an effective tool for monitoring terrestrial birds, identifying cryptic and often rare animals to species level, and providing valuable ecological information at species and community levels.

亚马逊西南部陆生鸟类的组装结构和动力学：相机陷阱案例研究

栖息地的空间分布，季节变化和活动模式会影响脊椎动物组合随时间的变化。陆生鸟类在热带森林的动态中起主要作用，但是由于它们隐蔽的色彩和难以捉摸的行为，因此几乎没有有效的方法来研究这些物种。我们使用在16个月（2017年2月至2018年6月）期间收集的相机陷阱数据来描述秘鲁东南部的陆生动物群，评估季节和两个主要生境（硬地和泛滥森林）中陆生动物群的组成变化程度，并确定陆生鸟类的日常活动方式。我们使用重叠分析来检查生态相似物种和同胞物种之间的时间共现。相机陷阱记录了16种，其中包括Tinamiidae科的8种。白鳞;; so科）和灰鸽子（Leptolila rufaxilla；哥伦比亚）。栖息地或季节之间的物种组成没有差异，并且栖息地之间的捕获率仅对于白喉的Tinamous（Tinamus guttatus）有所不同。在生态相似的物种和在坚硬的栖息地中发现的物种之间的活动模式重叠很高（白喉的Timinous和Cinereous Tinamous，Crypturellus cinereus）和两种栖息地类型（苍翅小号手和灰鸽子）。少量捕获可能是当地稀有或数量较少的物种阻碍了对陆生鸟类群落空间和季节模式的完整分析。我们建议进行更大的采样工作和更大的空间复制，以更好地了解陆地鸟类的空间和季节动态。在我们的研究领域和其他地方，进一步评估允许同胞共鸣的机制的研究将是有价值的。事实证明，在长期监测项目中使用相机陷阱是监测陆生鸟类，从物种水平识别隐性和稀有动物的有效工具，并在物种和社区水平提供有价值的生态信息。
