Akekee

The ʻakekeʻe (Loxops caeruleirostris) is a bird species in the family Fringillidae, where it is placed in the Hawaiian honeycreeper genus Loxops. It is endemic to the island of Kauaʻi where it is found in small numbers in higher elevations. Because of their similar size, shape, and unusual bill, the ʻakekeʻe and the ʻakepa (Loxops coccineus) were for some time classified as a single species. This was eventually changed, because of differences in their color, nesting behavior, and calls. https://en.wikipedia.org/wiki/%E2%80%98Akeke%E2%80%98e
