The Breeding Bird Survey

The Breeding Bird Survey is a systematic effort to monitor bird populations across North America. Volunteers and scientists count birds at fixed routes during the breeding season, providing important data on species presence, abundance, and trends over time. This information helps track how bird populations are changing, which can indicate the health of ecosystems and the impact of environmental factors. By collecting consistent, long-term data, the survey supports conservation efforts, informs policy decisions, and enhances our understanding of bird ecology.
