Thrashers and Mockingbirds: Mimidae

Hood Mockingbird (nesomimus Macdonaldi): Species Accounts

Physical characteristics: Hood mockingbirds are dull white on the chest and belly and streaked or spotted gray to brown coloring on the top. The dark wing feathers appear edged off-white. They may also have darker spots on the chest. The Hood mockingbird sports a black streak across its yellow-to-brown eyes, and has a black bill and legs.

Geographic range: The Hood mockingbird is found primarily on a small island in the Galápagos known as Hood Island (also known as Espantildeola).

The Hood mockingbird uses its long, curved beak to crack open seabird eggs, such as waved albatross eggs, in order to eat their contents. (© George Holton/Photo Researchers, Inc. Reproduced by permission.)

Habitat: Hood Island is a low-lying, flat-topped island with primarily rocky terrain and sand and pebble beaches. The available vegetation is primarily scrub. Fresh water is scarce.

Diet: The Hood mockingbird is an omnivore, which means it eats animals as well as vegetation. The bird uses its long, curved beak to crack open seabird eggs in order to eat their contents. It will also drink blood from the wounds of other living or dead animals, and scavenge carrion (decaying animal carcasses).

Behavior and reproduction: During nonbreeding season, Hood mockingbirds travel in large groups of around forty to forage and defend their territories. In the months of March and April when nesting time occurs, they split off into smaller groups. The species are cooperative breeders, meaning many birds will share feeding duties for the young in a group, not just the parent birds. The typically breeding group is approximately five adult males and two or three adult females.

Hood mockingbirds and people: Because of their remote location, Hood mockingbirds don't encounter people except in the form of ecotourists and researchers. When they do come in contact with humans, they are said to be unafraid and will readily approach them and scavenge for food and fresh water if accessible.

Conservation status: The Hood mockingbird is classified as a Vulnerable species because of its limited range and the risk that dangerous weather pattern changes could affect its population. ∎
