Four In Five Bird Species Cannot Tolerate Intense Human Pressures

Researchers found that 78% of the world’s bird species do not thrive in the most modified human-dominated environments and are also most likely to have declining populations.

Most people believe they are good neighbors, but most wild plants and animals would disagree. A new study by an international team of scientists has found that humans and their environmental modifications can have significant negative impacts on populations of flora and fauna β€” even those that live far from human-occupied areas. The study’s collaborators came to this conclusion by assessing populations of bird species across a variety of landscapes, from pristine habitats to human-dominated environments.

β€œThreatened species, and species with declining populations, are less tolerant to breeding in human-dominated habitats,” said the lead author of the study, community ecologist Emma-Liina Marjakangas, who currently is a postdoctoral researcher at Aarhus University where she studies how human-induced changes in ecological networks affect bird communities.

Currently, 14% of the world’s 11,000 bird species are threatened with extinction.
