Many animals of the Galapagos Islands are known for unusual foraging behaviors, often feeding in a way not typical for the taxon in question. In 2003, an adult Lava Heron (Butoiides striata sundevalli) was observed feeding on an adult Small Ground Finch (Geospiza fuliginosa). The endemic Lava Heron had not been previously observed feeding on these finches that are common throughout the islands. The behavior could represent a valuable feeding strategy for herons in a situation where aquatic food resources are temporally unpredictable, as well as an additional mortality risk for Galapagos Finches.
