Bar-breasted Honeyeater

Tiny gray insectivore of scrubby areas in the southwest U.S. and northern Mexico. Breeding males show a black cap with a thin white eyering; nonbreeding males have a thin black line over the eye. Females lack any black on the head. Note tail pattern from below: mostly black with bold white spots. Prefers dry, scrubby habitats such as desert washes, where pairs flit around in the low bushes. Listen for harsh scolding calls. Compare with Blue-gray Gnatcatcher, but note Black-tailed often looks drabber brownish-gray, and has much more black on the underside of the tail.

A large fruit-dove from Sulawesi. Very pale gray head has a diagnostic red mask that extends onto the nape as a black band. Juveniles duller, with subdued mask, and lack band on nape. Upperparts green in central and north Sulawesi, gray in the south. Underparts largely pale gray, with dark markings on the undertail. A montane species found in singles and pairs within the understory and canopy. Voice is a short, clipped “whoOP," often becoming slightly louder at the end.

Fairly large and thickset petrel of offshore tropical and subtropical waters across the Pacific; not seen from mainland. Plumage is highly variable (white-bodied and white-headed, dark-headed, or wholly dark), but all types have a white flash on the wingtip, including diagnostic white feather shafts on upperwing, which enhance this petrel’s resemblance to jaegers and skuas. Indeed, sometimes Kermadec Petrels chase and pirate other petrels, as do jaegers and skuas. Herald Petrel is very similar, but is smaller and slimmer with a longer and more tapered tail, and lacks white shafts on upperwings.
