Japanese Bush Warbler
Horornis diphone
A small, plain brown warbler of dense undergrowth. Note the narrow dark line through eye and the narrow white line above the eye. Occurs in forest understory, dense shrubland, bamboo thickets, and forest edges. Usually secretive and hard to see well, but males sometimes sing from an exposed perch. Song is a long introductory tone followed by a rapid warble, “uuuuuu-guisu,” from which the Japanese name is derived. Introduced to the Hawaiian Islands where it occurs on all of the main islands.

Jameson's Snipe
Gallinago jamesoni
Chunky snipe of very high elevations in the Andes. Plumage has a complicated pattern of brown, buff, and black; note extensive barring on underparts and thick, drooping bill. Might be confused with Noble Snipe, but does not have a white belly. Compared to Imperial Snipe, it is smaller and lacks the warm, cinnamon coloration. Jameson’s Snipe inhabits paramo grasslands and stunted forest near tree line. Shy and rarely encountered unless flushed, when it gives a burst of sharp, abrupt “kek” notes.
Sargasso Shearwater
Puffinus lherminieri
Small black-and-white shearwater with relatively long tail and somewhat rounded wings. Usually flies low to the water with fluttering wingbeats, but in strong winds it can fly with high wheeling arcs. Undertail coverts are typically dark, but this can be very difficult to see in the field. Compare with Manx Shearwater, which is larger with longer, more pointed wings, light undertail coverts, and a darker face. Found over warm tropical waters, especially around floating mats of Sargassum weed. Often seen singly or in pairs but can gather in loose flocks, sometimes loafing with other shearwater species.
Purple Finch
Haemorhous purpureus
Males suffused with raspberry red, especially on head and breast. Compared to House Finch, males lack distinct streaks on sides and are overall more colorful, especially on back and wings. Females and first-year males have contrasty head pattern with pale eyebrow and darker cheek; also note well-defined streaks on sides. Breed in coniferous or mixed forests. Winters in a wider variety of habitats with trees. Visits feeders.
