African birds of prey show signs of population collapse, researchers say
African raptors that hunt during the day face an extinction crisis, with populations decreasing among dozens of species of birds of prey, researchers said in a study published Thursday.
Researchers used data from the last 40 years to analyze the populations of 42 of the country’s 106 raptor species, they wrote in the journal Nature Ecology and Evolution. Nearly 90% of the studied species experienced population declines.
“Africa is at a crossroads in terms of saving its magnificent birds of prey,” Dr. Darcy Ogada, one of the study’s authors, said in a press release. “In many areas we have watched these species nearly disappear.”
population growth among major areas, with the population in sub-Saharan Africa projected to double by 2050, according to the United Nations.
It’s not just Africa facing declining populations of birds. In a 2019 study, scientists said that the U.S. and Canada have lost 29% of their bird populations — amounting to nearly 3 billion birds. That same year, scientists warned that worldwide, 1 million species of plants and animals were at risk of extinction.
