North American Bird Decline Accelerates
New research shows bird populations across North America are declining faster each year.
35 Years Of Data Analyzed
Scientists studied 261 bird species using survey data collected from 1987 to 2021.
Nearly Half Of Species Declining
About 47% of studied bird species show significant population declines.
Agricultural Hotspots Identified
The fastest bird declines appear in regions with intensive farming activity.
Three Major Decline Regions
California, the Midwest and the Mid-Atlantic show the fastest population losses.
Farming Practices Linked To Decline
Heavy pesticide and fertilizer use may harm bird habitats and food sources.
Food Sources Are Disappearing
Many birds rely on insects. Pesticides reduce insect populations they depend on.
Climate Change Adds Pressure
Rising temperatures are also linked to accelerating bird population losses.
Even Common Birds Affected
Many widespread bird species are declining, not just rare ones.
Birds Support Ecosystems
Birds help control pests, spread seeds and maintain ecosystem balance.
Conservation Can Slow The Decline
Experts say better farming practices and habitat protection could help birds recover.
