Man is responsible for this become extinct by 1,430 species of birdsaccording to new research published in the journal Nature communication.

Specialists believe that almost all of these extinctions occurred due to a series of man-made factorsranging from hunting and consuming birds to destruction of habitat and the introduction of invasive species. Most of these birds have become extinct since the end of the last century ice age.

This number of bird species represents approx 12% of the total over the past 126,000 years. The figure doubles current estimates and includes species that disappeared before written records even existed.

“Our study shows that the human impact on bird diversity is much greater than previously recognized,” study author Rob Cooke, an ecological modeler at the UK Center for Ecology and Hydrology, said in a statement.

“Humans have rapidly destroyed populations birds due to habitat loss, overexploitation and the introduction of rats, pigs and dogs that attack bird nests and compete with them for food,” the specialist said. “We show that “Many species became extinct before written records were made and left no traces; they have disappeared from history.”

According to the article, The extinction rate of bird species is more difficult to study than that of other living organisms because of their delicate bones. For that reason, most previous studies have focused only on extinctions over the past 500 years, based on data on current species.

This study examined fossil records on islands such as Fiji, Hawaii, New Zealand and other islands in the western Pacific Ocean, and examined documentary sources.

Most of the extinctions have occurred since the beginning of the Holocene and the end of the late Pleistocene, about 11,700 years ago, just after the end of the last ice age. And 55% of these extinctions had not yet been discovered. (JO)
