It is a species of bird found on the Galapagos Islands. The Galapagos Cormorant, Phalacrocorax harrisi, has lost its ability to fly. This is one of only a few cormorants that are flightless in the entire world. This species' loss of flight is an evolutionary phenomenon known as "flightlessness," and can happen on islands with fewer predators or less competition.
It has become a skilled swimmer rather than a flyer. The cormorant uses its wings to propel through the water as it hunts for fish or other marine prey. Using this adaptation, it can exploit the abundance of marine resources in the Galapagos Islands. It has reduced the size of its wings and muscle mass, which makes it unable to sustain flight.
Flightless cormorants are an interesting and unique example of species adapting to niches and environments that they find themselves in, even though it may mean losing some of the capabilities common among their family.
