Also, many birds live in places that are hard to reach, where people don't often get a chance to observe and count them. The number of species doubled because of wrong counting of species as well as the discovery of more species. Owls are generally territorial birds to an extent that they may not give up their homes even when faced with danger. There are fewer than 1,000 living adults of this species so the Cambodian government has set up a special conservancy to protect the birds.
