Interesting article about the report on the State of North America’s Birds 2016 and 1 billion birds being gone from North America since 1970. It isn’t just my imagination that there are a lot fewer birds now than back when I started birding years ago.
A billion birds have disappeared from North America since 1970, and a third of bird species across the continent are threatened with extinction…
The first State of North America's Birds report finds that of 1,154 bird species that live in and migrate among Canada, the U.S. and Mexico, 432 are of "high concern" due to low or declining populations, shrinking ranges and threats such as human-caused habitat loss, invasive predators and climate change.
