Greenfinch numbers in Britain have dropped by 67% since 1979, putting the species at risk of extinction due to disease spread at feeders.
Nearly half of the 261 species studied showed big enough losses in numbers to be statistically significant and more than half of those declining are seeing their losses accelerate since 1987, according to Thursday's journal Science. The study is the first to look at more than the total bird population by examining the trends in their decrease, where they are shrinking the most and what the declines are connected to.
Between 1940 and 2020, the average body mass of birds in 10 Indigenous and local communities on three continents declined by up to 72%. For the Indigenous communities who were interviewed, birds often hold immeasurable symbolic and ceremonial significance. Thus, ritual dances, songs, and place names are at risk of being lost in the face of this loss of biodiversity.
'Today's Red List update, launched at the IUCN Congress in Abu Dhabi, shines a light on both the urgent challenges and the powerful possibilities before us,' said Dr Grethel Aguilar, IUCN Director General.
