SPONSORED ADVERTISEMENTS

General

Iiwi: A medium-sized honeycreeper, vibrant red plumage overall with black wings and tail. Wings show contrasting white patch on inner secondaries. Salmon-colored bill is long and decurved. Sexes are similar. Legs and feet are pink. Juveniles have ivory or light brown bills and black-tipped, green-yellow to a mustard-yellow feathers that fade to yellow as they age, wings and tail are dark gray with tawny to white feather edgings; tertials are pale gray in place of the adults' white; may show some red on scapulars or face.

Range and Habitat

Iiwi: Large colonies exist on the islands of Hawaii, Maui, and Kauai, common in wet forests at high elevations. There are fewer than 50 individuals on the lower elevation islands of Oahu and Molokai, and they are now extinct from the island of Lanai. These birds prefer to keep hidden among the leaves.

Breeding and Nesting

Iiwi: The peak breeding season is between February and June. Both sexes aid in the construction of the nest. Two to four white eggs with reddish brown marks are laid in a cup nest of twigs, ferns and lichens built in the crown of the ohia tree. The female incubates the eggs for 14 days. The chicks fledge 21 to 24 days after hatching.

Foraging and Feeding

Iiwi: They feed mostly on the nectar of the Ohia flower, but will also take other nectar and insects from the understory. They are very aggressive, and will chase away smaller species from their feeding trees. They forage mostly in the mid and upper strata of the forest canopy, never on the ground. Most moisture is obtained from nectar, but they also take water from leaf surfaces and flowers.

Vocalization

Iiwi: Song is an unusual collection of whistles, the sound of balls dropping in water, the rubbing of balloons together, and the squeaking of a rusty hinge.

Similar Species

Iiwi: Apapane has a shorter, less curved black bill, is a more crimson color, and has white undertail coverts and lower abdomen.
