There are two endemic subspecies of owls in the Galapagos: the Barn and the Short-eared Owl.
The short-eared owl (Asio flammeus galapagoensis) has changed its night hunting behavior to eventual day hunting in order improve its catches. They are carnivorous and can prey on bigger birds than themselves such as the blue-footed boobies. In Genovesa Island, they mainly feed on storm petrels that nest between the rocks in deep caves. Here, they have learned to wait for the petrels to come in and out from the nests to catch them unaware. They are easier to be seen in islands where the Galapagos hawk is absent.
The Barn Owl (Tyto alba) is found all around the world. There are about 46 different species; the one found in the Galapagos is the smallest one. The interesting shape of its face resembles a satellite in order to focus all noises to its ears. As they fly low, they are able to hunt mammals and reptiles. This is one of the very few bird species where the female has a more attractive plumage than the male. They lay between 3 to 6 eggs, and live about 2 years.
Where to find them:
They can be found inSanta Cruz, Isabela, San Cristóbal and Fernandina; it is believed that it is now extinct on Floreana Island.
