Although 'I'iwi are still fairly common on most of the Hawaiian islands, it is rare on O'ahu and Moloka'i and no longer found on L?na'i. It is thus exposed to harmful low elevation disease organisms and high mortality This migration also makes it hard to assess the total populations on the islands. Based on the rather limited information available up-to-date, some individuals defend Metrosideros polymorpha (ōhiʻa lehua trees, also referred to as ōhi‘a trees) with plenty of flowers.

USGS wildlife biologist Paul Banko is studying Iiwi diet on the refuge to help determine what plants would host more of the food resources that Iiwi eat. Their diet consists Scientists take the lead. [10] They are most abundant in mesic to wet forests at higher elevations.[11]. ‘I‘iwi live in native forests where nectar is plentiful. ʻIʻiwi was formerly classified as a near threatened species by the IUCN, but recent research has proven that it is rarer than previously believed. ‘I’iwi predominantly feed on nectar, and are regularly seen in flowering ‘ōhi’a trees.

They can hover much like hummingbirds to drink the nectar from the flowers. Also known as the “Scarlet Honeycreeper”, the ‘i‘iwi is a passerine bird which belongs to the family of the Hawaiian honeycreepers. Consequently, it was uplisted to Vulnerable status in 2008.
