[3] They forage on native plants including ʻōhiʻa, koa, pilo, alani, ʻōhelo, kōlea, pūkiawe, and ʻōlapa.

[4] Maui ʻalauahio can be seen at Hosmer's Grove at Haleakalā National Park and Polipoli Springs State Recreation Area.

[1] The species is also limited to higher elevations due to its high susceptibility to avian malaria, with a 75% mortality rate after exposure to an infected mosquito bite.
