'I'iwi

Drepanis coccinea

The 'I'iwi is a large, nectarivorous honeycreeper (~6 in in length). They are brilliant scarlet with black wings and tail. Their bill is long, deeply decurved, and peach-colored. Immature are dull yellow with black spots. Bills are dusky brown at first and becomes brightly colored with age.

Habitat & Behavior

Often found in flowering ʻōhiʻa lehua, māmane, and 'ākala. Slow and deliberate in movements, keeps to the interior of leafy branches, rarely in the open. Wings produce an audible flutter in flight.

Voice: An almost infinitely varied repertoire of creaks, whistles, gurgles, and reedy notes often joined into a halting song. Some random calls sound like a child playing with a rusty harmonica. A loud rusty-hinge call diagnostic. May give humanlike whistles, or imitate other native birds.

Distribution & Conservation

Endemic to the main Hawaiian islands in native forests above 600m. Common to abundant on Hawai'i, Maui and Kaua'i, rare or almost none existent on Moloka'i, Oʻahu, and Lana'i.

Though the species remains common in some areas the 'I'iwi has seen the most drastic population decline of any Hawaiian honeycreeper in recent decades. With few exceptions the species is vanishing from nearly all parts of its former range. The USGS recently published an analysis of population trends for the species and found that <1% of individuals live outside of Hawai'i island and east Maui. You can view their report here

In 2016, US Fish and Wildlife Service (USFWS) proposed that the 'I'iwi be protected under the Endangered Species Act as a threatened species. The review was initiated by a petition filed with USFWS in 2010 by the Center for Biological Diversity and Dr. Tony Povilitis. Iiwi are highly susceptible to avian malaria and are in a decline island wide. Creating more high elevation forest that is ungulate and mosquito free will help protect the birds.
