It was endemic to Hawaii. It became extinct due to habitat loss. It disappeared at around the same time as its Oahu cousin. DescriptionIt was a yellowish bird with a two-inch-long thin whitish-yellow bill. It had small olive green wings which it used to flit from tree to tree to look for insects like beetles and caterpillars. BehaviorIt was seen gleaning the trees in search of insects. The bill of the akialoa was also designed for more than bug extraction. The akialoa also fed on nectar in the flowers of lobelias and o’hia blossoms. Its long bill could easily fit into petals of long flowers and took pollen from flower to flower on its forehead. It was collected at several places. It was once thought to be the same species as the Maui and Oahu form, but when specimens were compared all together the scientist saw that all three were different species.{{citation needed|date=October 2015}} ExtinctionWith the loss of the trees and the flowers, the bird had no shelter or food and disappeared in 1940.[1] References1. ^1 {{IUCN|id=22728910 |title=Hemignathus obscurus |assessor=BirdLife International |assessor-link=BirdLife International |version=2013.2 |year=2012 |accessdate=26 November 2013}} External links
