Hawaiʻi creeper is able to climb up and down trees. It uses its short, sharp beak to probe bark for insects residing underneath. If available, it will sip nectar from koa ("Acacia koa") or ōhia lehua ("Metrosideros polymorpha"). The breeding season of the Hawaii creeper lasts from April to July, during which female birds lay one to three eggs. Nests are hidden in a tree cavity or built on a high branch in either a koa ("Acacia koa") or a ōhia lehua ("Metrosideros polymorpha"). Eggs hatch after around thirteen days. The Hawaii creeper was put on the endangered species list in 1975;
ʻApapane Lānai. Apapane generally feed on nectar from flowers, preferably from the "ōhia lehua" ("Metrosideros polymorpha") tree. These birds are mainly found in "koa" ("Acacia koa") and "ōhia lehua" forests where the flower count is high. Although primarily nectarivorous, the diet of a grown apapane also includes a variety of insects like grasshoppers, caterpillars and bugs of all sorts. The breeding season is from January through July. The nest of the apapane is usually placed in the crown of a "ōhia lehua" ("Metrosideros polymorpha"); nests have been found in tree cavities and lava tubes as well as in the top of
