Honeycreepers are native to the Hawaiian archipelago. Suggest how the ancestors of Hawaiian honeycreepers reached the Hawaiian Islands from the North American mainland, using the information about prevailing wind currents shown in the figure below.

A two-panel diagram illustrating the colonisation of the Hawaiian Islands from North America by ancestral finches under the influence of strong jet streams and storm winds, followed by adaptive radiation into different species like Drepanis kauaiensis and Drepanis coccinea across the islands.
