Iiwi
Drepanis coccinea
The adult ʻiʻiwi is mostly scarlet, with black wings and tail and a long, curved, salmon-colored bill used primarily for drinking nectar. The contrast of the red and black plumage with surrounding green foliage makes the ʻiʻiwi one of Hawaiʻi's most easily seen native birds. Younger birds have golden plumage with more spots and ivory bills and were mistaken for a different species by early naturalists. Observations of young birds moulting into adult plumage resolved this confusion. Along with the Hawaiʻi Mamo, ʻiʻiwi were used in the feather trade. Voice: The ʻiʻiwi has a complex and varied song, which has been compared to the sound of whistles, balls dropping in water, the rubbing of balloons together, and the squeaking of a rusty hinge. Both sexes have been observed to mimic other bird calls.

Spot-crowned Euphonia
Euphonia imitans
The spot-crowned euphonia is about 10 cm (3.9 in) long and weighs about 14 g (0.49 oz). It is a small euphonia with a stubby bill. The species is sexually dimorphic. Adult males have a bright yellow forehead; the patch extends to the rear of the eye and is speckled with black. The rest of their crown and their face, nape, throat, chest, and upperparts are steely blue-black. Their upperwing coverts are a slightly glossy blue-black. Their flight feathers are dusky with a blue-black tinge and white bases on the inner webs of most feathers. Their tail is dusky with a blue-black tinge. Voice: The spot-crowned euphonia "produces rolling, buzzy utterances". Its song "typically consists of a note or phrase repeated 5–8 times, followed by abrupt shift to another series; some songs are clear sweet warbles, others chaffy or wheezy and dry, e.g. chip a cheer weet; chip tuck tuck; wee churee-cha..., and so on". A song bout may last up to 30 minutes.
