The Great Backyard Bird Count, a global initiative launched 30 years ago, mobilizes birdwatchers around the world to observe and report on bird populations, providing crucial data to advance environmental research and conservation efforts.

Why it matters

By engaging the public in scientific monitoring, the bird count helps fill critical data gaps and track the health of ecosystems, which are under increasing threat from climate change, habitat loss, and other human impacts.

The details

The annual four-day event encourages anyone with basic birding skills to count and report the birds they see, creating a snapshot of avian populations across continents. This crowdsourced data informs scientific studies on migration patterns, population trends, and the impacts of environmental changes on birds.

  • The 2026 Great Backyard Bird Count took place from February 18-21.
  • The event has been held annually since its launch in 1998.
