Long-term Population Trends for America’s Birds
~† Shorebirds indicator trend data has not been updated since 2019.~
- 5 Years After the 3 Billion Birds Lost Research, America Is Still Losing Birds: A 2019 study published in the journal Science sounded the alarm—showing a net loss of 3 billion birds in North America in the past 50 years. The 2025 State of the Birds report shows those losses are continuing, with declines among several bird trend indicators. Notably duck populations—a bright spot in past State of the Birds reports, with strong increases since 1970—have trended downward in recent years.
- Conservation Works: Examples spotlighted throughout this report—from coastal restoration and conservation ranching to forest renewal and seabird translocations—show how proactive, concerted efforts and strategic investments can recover bird populations. The science is solid on how to bring birds back. Private lands conservation programs, and voluntary conservation partnerships for working lands, hold some of the best opportunities for sparking immediate turnarounds for birds.
- Bird-Friendly Policies Bring Added Benefits for People, and Have Broad Support: Policies to reverse bird declines carry added benefits such as healthier working lands, cleaner water, and resilient landscapes that can withstand fires, floods, and drought. Plus birds are broadly popular—about 100 million Americans are birdwatchers, including large shares of hunters and anglers. All that birding activity stimulates the economy, with $279 billion in total economic output generated by birder expenditures.
Less bugs (food) from more pesticides and inhospitable mono-culture farm land, suburban sprawl, toxic car infrastructure and global warming are all likely contributors
