Many Birds Are on the Decline
Read the full article about long-term bird declines in our magazine.
Bird numbers fluctuate for natural reasons, and that can be the explanation for changes you see in your yard from month to month. But it’s also true that many populations of bird species have been declining gradually but consistently for many years.
In September 2019, a comprehensive study of 529 bird species in the U.S. and Canada found a net loss of 2.9 billion breeding birds, or 29% of the overall population, since 1970. The research was published in the journal Science by a team of researchers led by the Cornell Lab of Ornithology.
These losses aren’t restricted to rare or threatened species. In fact, common birds have suffered the greatest losses, including beloved species like Dark-eyed Juncos (down by 168 million) and Red-winged Blackbirds (down by 92 million). Read more.
While the news is distressing, we’ve highlighted actions that governments and businesses can take to stem the losses, as well as 7 Simple Actions to Help Birds that anyone can take at home.
How to Look Up Estimates of Bird Population Trends
- The North American Breeding Bird Survey estimates population change since 1966 for most bird species in the U.S. and Canada.
- Partners In Flight maintains a Watch List. You can also refer to their full database on conservation status of North American birds.
- The 2016 State of North America’s Birds report found that over 37% are of high conservation concern.
