Explanation:

Great hornbill which was earlier categorised as “Near Threatened”. It is now “Vulnerable” due to high hunting pressure coupled with habitat loss and deforestation. Vulnerable (VU) species is a species which has been categorised by the IUCN as likely to become endangered unless the circumstances threatening its survival and reproduction improve. It is therefore considered to be facing a high risk of extinction in the wild.

Where as the criteria of species numbers have decreased, or will decrease by 80% within three generations is applicable to Critically Endangered (Cr) of IUCN threatened species.
