The North American Breeding Bird Survey (BBS) is a large-scale, long-term monitoring program designed to track the status and trends of North American bird populations.

The Breeding Bird Survey (BBS) is a standardized and one of the rare long-term databases of ecological communities. The BBS permits us to understand long-term changes in North American bird communities, such as their responses to climate change (migration phenology), overall diversity trends (indicators of the effect of habitat loss or alteration), and better understand ecological interactions over long time scales. Breeding data may be influenced by climate change.

繁殖鸟类调查（Breeding Bird Survey，BBS）是一项标准化的、极为稀有的长期生态群落数据库之一。该调查使我们得以探究北美鸟类群落的长期动态变化，例如它们对气候变化的响应（迁徙物候）、整体多样性变化趋势（可作为栖息地丧失或改变影响的指示指标），并深化对长时间尺度下生态相互作用的认知。该调查的繁殖数据可能受到气候变化的影响。
