The Breeding Bird Atlas 2 (BBA2)

The Breeding Bird Atlas 2 (BBA2) is a comprehensive survey that maps where birds breed across a specific region, often over multiple years. By collecting data from birdwatchers and researchers, it identifies the distribution, abundance, and changes in breeding populations. The goal is to improve understanding of bird habitats and inform conservation efforts. BBA2 builds on earlier surveys, providing updated information crucial for protecting bird species and their environments. Ultimately, it helps scientists and policymakers make informed decisions to preserve avian biodiversity.
