Why the Hawaiian honeycreepers are endangered species to extinction.

Due to climate change mosquitoes on the Hawaiian islands manage to go to higher altitudes pushing the habit of the birds that have nowhere to go. Also the insects give disease to the birds such as avian malaria.

The Hawaiian honeycreepers have evolved from a group of Eurasian birds. The remarkable about them is that with storms the Eurasian birds (rosefinches) managed to irrupt the remote islands of Hawaii, some died during the trip from Asia but some survived.

The Polynesians introduced rats, chickens, pigs and dogs, hunted and converted habitat for agriculture. Also the introduction of foreign birds and the hunting of the honeycreepers for their feathers from native Hawaiians were reasons to decrease their numbers.

Most of the species of honeycreepers are seeds and nectar eaters but of specific trees that have been destroyed by introduction of goats and pigs.

Lobelia plants have evolved to be pollinated by the honeycreepers and about a quarter of these plants are now extinct.

Other honeycreepers feed on insects that depend on forests that have been removed.

The moral lesson of these endangered to extinct birds is that million of years of evolution in remote areas can be vanished in a few years because of human intervention. The forests have been cut down for wood or agricultural reasons without letting enough space for the birds. The events that happened on the past are recognised today as wrong which means that the remaining forests in our ear must have a chance to increase again by better management. Most of the people should know areas of forests close to where they live and should be aware not to have any more reduction or even better they should go into manage these green areas so as to increase habitat for rare species. A loss in biodiversity is a loss of value on earth and this has effects on humans by making life more average and more sad.
