The Flightless Cormorant is a unique species of bird found exclusively on the Galapagos Islands.

It’s one of the most remarkable animals there, as it’s the only known cormorant that has lost its ability to fly due to evolutionary pressures in this isolated environment.

The Flightless Cormorant has an impressive wingspan and strong webbed feet for swimming, but these adaptations are not enough for flight.

Its diet consists mainly of fish caught from coastal waters near its nesting sites, which it dives into with great skill and agility despite being unable to take off from land or water.

The Mangrove Finch is a species of bird belonging to the Darwin’s finch group from the Thraupidae family, which are endemic in Galápagos Islands.

It was formerly found on Fernandina and Isabela, but recent surveys have failed to detect them on Fernandina.

Unfortunately it has been classified as critically endangered with only an estimated population of 2 due its decreasing habitat caused by human activities such as deforestation for agricultural purposes and grazing livestock.

The destruction of their natural habitats also increases vulnerability towards introduced predators like rats or cats that can hunt these birds easily since they don’t have experience dealing with them yet.
