Which Backyard Birds Are Declining in Your State? 59 Years of Data

Across the United States, 23 of 50 common backyard birds have clearly declined since 1966, and 11 have clearly increased, according to our analysis of the U.S. Geological Survey’s newest Breeding Bird Survey results. The losers are mostly the birds of open yards and farm edges: house sparrows, grackles, blackbirds, starlings and towhees. The winners are feeder regulars: nuthatches, wrens, woodpeckers, titmice, bluebirds and cardinals. Below is what changed nationally and a state-by-state table for 49 states.

The short version

  • House sparrows are down almost everywhere: clearly declining in 41 of the 47 states with enough data, and rising in none.
  • Blackbirds are falling: red-winged blackbirds are clearly down in 33 states, common grackles in 32 and European starlings in 30.
  • Feeder birds are winning: the red-bellied woodpecker, Carolina wren and white-breasted nuthatch are clearly up in 20 or more states each and clearly down in none.
  • Hardest-hit state: Oregon, where 16 of 27 backyard birds with reliable data are clearly down and only one is clearly up.

Where these numbers come from

The North American Breeding Bird Survey is a volunteer count run in the U.S. by the USGS. Each June, observers drive fixed roadside routes and count every bird they see or hear at 50 stops. USGS scientists turn those counts into a yearly trend for each species in each state. We used the 2026 release, covering 1966 to 2025, and kept only the estimates USGS rates as reliable: at least 14 routes, enough birds and enough precision (no data-quality warning). “Clearly up” or “clearly down” means the trend’s 95% credible range sits entirely above or below zero, using USGS’s own significance flag.

Two limits matter. This is a June count, so it tracks birds that nest in a state, not winter visitors at your feeder. And a trend shows how much a bird changed, not why.

*Change since 1966 is our calculation: the yearly trend compounded over 59 years. Treat it as a rough size of the change. The Eurasian collared-dove, a non-native bird that spread across the country after the 1980s, is up more than tenfold and left out of this table.

Backyard bird trends in every state

For each state, the table counts how many of our 54 backyard birds have reliable USGS data there, how many are clearly down or clearly up since 1966, and the biggest mover each way. Hawaii is not part of the survey’s core results, and Rhode Island has too few routes for a reliable estimate.

Which birds we counted as backyard birds

We used 54 species that commonly nest in U.S. yards, parks and neighborhoods or visit feeders: cardinals, jays, robins, doves, finches and goldfinches, chickadees, titmice, bushtits, woodpeckers and flickers, nuthatches, wrens, mockingbirds, catbirds and thrashers, bluebirds, sparrows, starlings, blackbirds, cowbirds and grackles, orioles, hummingbirds, phoebes, swallows and martins, waxwings, crows, grosbeaks, towhees, scrub-jays and Steller’s jays, buntings and collared-doves. Not every species lives in every state, so each state’s count is different.

How we built this page

  • Source file: BBS_Core_Trends_1966-2025.csv from the USGS ScienceBase data release (doi:10.5066/P1OSNSFC), state rows and the United States row.
  • Reliable data only: rows with a blank USGS credibility code (at least 14 routes, at least 1 bird per route, enough precision).
  • “Clearly up/down” = the USGS significance field (95% credible interval excludes zero).
  • Change since 1966 = (1 + yearly trend) to the 59th power, minus 1; gains over tenfold are shown as “more than 10 times as many.”
