A recently-published report has revealed widespread declines in U.S. birds in all habitats except one.
On this page, we examine the key findings of the report, and take a closer look at 10 US bird species identified as “tipping-point” birds – species that have suffered significant decline in their population in the last 50 years.
How many of these ten birds have you seen recently? Have you noticed a decline in their numbers - or in the numbers of any other species? Let us know in the comments section.
