Honeycreepers are native to the Hawaiian Islands. Suggest how the ancestors of Hawaiian honeycreepers reached the Hawaiian Islands from the North American mainland, using the information about prevailing high-altitude jet streams shown in the figure below.

A two-panel map. Panel 1 shows the Pacific Ocean with North America on the right and the Hawaiian Islands on the left, with a dashed arrow representing high-altitude jet streams blowing westward. Panel 2 shows the Hawaiian Islands (Kauai, Oahu, Maui, Hawaii) with labels of different honeycreeper species: Loxops caeruleirostris on Kauai, Loxops wolstenholmei on Oahu, Loxops ochraceus on Maui, and Loxops coccineus on Hawaii.
