The number of birds living in tropical forests has plummeted by up to 90 percent in just 40 years, according to new research.

Conservationists described the decline as “concerning” after finding that the vast majority of species studied in a Panamanian rain forest had seen declines in numbers of at least 50 percent between 1977 and 2020.
