Answer 2

Because its small size.  and its enviroment is

endemic—that is found nowhere else on earth. A single calamitous event, such as a hurricane, earthquake, or disease epidemic, could wipe out the entire population at one time. This also increases liklyhoods of inbreeding and thus genetic problems.

all because they are only in that one single spot and that one single enviroment.

Answer 3

human development destroys habitat.

Answer 4

Human development destroys habitat.  This is the reason almost every endangered species on the planet is endangered.  Also, in Hawaii...when the birds are forced to lower elevations due to habitat destruction, they are bitten by mosquitoes that transmit avian malaria to them.  These mosquitoes cannot live in high elevations and used to never come in contact with these birds, but now that the birds have no where to go but down..it has become an epidemic.  There are also many non-native plants and animals (feral pigs, mongoose, etc.) that affect the bird population negatively as well.

Also, birds are not hunted for feathers in Hawaii..that would be a violation of the Migratory Bird Treaty Act and the Endangered Species Act.  Birds being killed for feathers stopped decades ago in the US.  It is illegal to even pick up a wild birds feather off the ground, let alone hunting birds for them.
