Today we woke up anchored in the middle of a caldera of the main extinct volcano that formed this old island. Tower Island is located north of the equatorial line and therefore sits away from the wind and cold-water currents that bade the southern and western archipelago; this has resulted in Galapagos hawks never having settled here. Therefore short-eared owls have evolved into the apex predator of this island, hunting for storm petrels in broad daylight. Adaptations that lead to speciation.
