... here is yet another very important "Citizen Conservation Biologist Survey" collecting much needed data ... for your consideration.
Every summer thousands of expert birders hit the road—not just for fun, but for science! 🚗📊
Over 2,500 volunteer birders take part in the North American Breeding Bird Survey (BBS)—a massive, continent-wide effort led by the U.S. Geological Survey Eastern Ecological Science Center, in partnership with Environment and Climate Change Canada and the Mexican National Commission for the Knowledge and Use of Biodiversity, to monitor bird populations across North America.
Here’s how it works:
🌄 Volunteers skilled in bird ID spend five early-morning hours driving a 25-mile route.
🛑 They stop roughly every ½ mile, or 50 times along the way.
⏰ At each stop, they count every bird they see or hear for exactly 3 minutes.
📍Each route is surveyed once per year—rain or shine, bugs or… bugs!
These data points might sound small, but together they build BIG science. With over 4,800 survey routes located across the continental U.S, Canada and northern Mexico, these BBS data have:
📉 Revealed major declines in North American birds: data from BBS helped document the loss of 3 billion birds in North America since 1970 and are used extensively in the State of the Birds Reports.
🌳 Informed national conservation policy and land-use planning.
📚 Fueled 800+ scientific publications.
A huge thank-you to the dedicated volunteers who help us understand and protect North America’s bird populations. Your commitment makes all the difference. 👏
