Yes, the wings of a Galapagos cormorant can be considered vestigial structures. The article mentions that the Galapagos cormorants have lost their ability to fly and their wings have become smaller and less functional. This is likely due to the fact that the cormorants' ancestor, which could fly, arrived on the Galapagos Islands and over time, the cormorants adapted to their environment and no longer needed to fly. As a result, their wings have become vestigial structures that serve little to no function for flight.
