As I have mentioned before, most of the animals in the Galápagos are very tame and regard human visitors with indifference or curiosity instead of fear. This mockingbird investigated our stuff while we played on the beach.
It is probably a Hood Mockingbird (Hood is the English name for Española Island), which are notorious for their interest in tourists.
These birds are endemic to the island, meaning they are only found here; but they are of course closely related to the several other species of mockingbirds on other islands. Its distinctive identifying feature is its long, curved beak.
