The breeding season of the Hawaiʻi creeper lasts from April to July, during which female birds lay one to three eggs.

It has also been found in lower elevations in areas like the common ʻamakihi and apparently handles the diseases better than other species just like it.

The other pressure is the fact that these birds are being eaten by rats which cause the populations to drop very quickly.

The nests of the Hawaiʻi creepers are low to the forest floor which leave the bird vulnerable to predators such as rats [2] The species is eaten as eggs, chicks, and even as full-fledged adults.

Now its northern population is being protected in the same area as is the ʻakiapolaʻau and other native birds: Hakalau Forest National Wildlife Refuge.
