Breeding landbird point counts (DP1.10003.001)

This data product contains the quality-controlled, native sampling resolution data from NEON's breeding landbird sampling. Breeding landbirds are defined as “smaller birds (usually exclusive of raptors and upland game birds) not usually associated with aquatic habitats” (Ralph et al. 1993). The breeding landbird point counts product provides records of species identification of all individuals observed during the 6-minute count period, as well as metadata which can be used to model detectability, e.g., weather, distances from observers to birds, and detection methods. The NEON point count method is adapted from the Integrated Monitoring in Bird Conservation Regions (IMBCR): Field protocol for spatially-balanced sampling of landbird populations (Hanni et al. 2017; http://bit.ly/2u2ChUB). For additional details, see protocol [NEON.DOC.014041](http://data.neonscience.org/api/v0/documents/NEON.DOC.014041vF): TOS Protocol and Procedure: Breeding Landbird Abundance and Diversity and science design [NEON.DOC.000916](http://data.neonscience.org/api/v0/documents/NEON.DOC.000916vB): TOS Science Design for Breeding Landbird Abundance and Diversity.

本数据集产品包含经过质量管控、保留原生采样分辨率的国家生态观测网络（National Ecological Observatory Network, NEON）繁殖陆地鸟类采样数据。繁殖陆地鸟类的定义为“通常不包含猛禽与高地猎禽的小型鸟类，且一般不与水生栖息地相关联”（Ralph等，1993）。本繁殖陆地鸟类定点计数数据集产品提供6分钟计数周期内观测到的所有个体的物种识别记录，同时包含可用于构建可检测性模型的元数据，例如天气状况、观测者与鸟类的距离以及检测方法。

NEON定点计数方法改编自《鸟类保护区域综合监测（Integrated Monitoring in Bird Conservation Regions, IMBCR）：陆地鸟类种群空间平衡采样野外规程》（Hanni等，2017；http://bit.ly/2u2ChUB）。如需更多详细信息，请参阅规程文档《NEON.DOC.014041》（http://data.neonscience.org/api/v0/documents/NEON.DOC.014041vF）：陆地观测系统（Terrestrial Observation System, TOS）规程与流程：繁殖陆地鸟类丰度与多样性，以及科学设计文档《NEON.DOC.000916》（http://data.neonscience.org/api/v0/documents/NEON.DOC.000916vB）：陆地观测系统繁殖陆地鸟类丰度与多样性科学设计。
