Marble-faced Bristle-Tyrant

Rare, endangered, and poorly known hummingbird restricted to mangroves and adjacent scrubby areas along the Colombian coast. Male has sapphire underparts extending from throat all the way to belly, and lacks the distinct hood typical of the more common Sapphire-throated Hummingbird. Female’s plumage is not known with certainty, but likely resembles female Sapphire-throated Hummingbird, which has white central underparts bordered by green flanks, and white tail tips.

Small, noisy woodpecker, common in a variety of forested habitats including urban parks. The body is largely olive-green and heavily barred, including the tail. Note two white stripes above and below the eye and a pale throat. Males have a red crown that is lacking in females.

A large gadfly petrel with a pale white head and a distinctive dark eye-patch. Back is pale gray with darker outer wings, creating an “M” shape on the back. Look for stout black bill and pinkish-colored feet. Breed on Antipodes and Auckland Islands in the New Zealand region and also on subantarctic Indian Ocean and Macquarie Islands. Forages between the subantarctic and Antarctic convergence zones. Three similar species: Soft-plumaged Petrel is smaller with gray-brown head and band on upper breast; Gray Petrel is larger with a smaller, darker head, a pale green bill, and a long neck; and pale morph Kermadec Petrel is smaller, lacks an eye patch, has darker upperparts, and shows white patches under the wing.
