More than 500 bird species are likely to be wiped out from the face of the Earth in the next 100 years, due to climate change and habitat loss, according to a study on Tuesday.

Researchers from the University of Reading in the UK noted that the number is three times higher than all bird extinctions recorded since 1500 CE.

The study, published in the journal Nature Ecology and Evolution, reveals that the bare-necked umbrellabird, the helmeted hornbill, and the yellow-bellied sunbird-asity are the most vulnerable.
