Chestnut-capped Foliage-gleaner
Clibanornis rectirostris
Large foliage-gleaner with startling yellow eyes and a long bill and tail. Rather uniform rufous above and paler below. Found in gallery forests near water, mostly foraging on the ground or understory, sometimes with mixed-species flocks. The call is a very loud cackling “ka-ka-ka karaka ka-ka-ka” with some rattling noises interspersed.

The henna-capped foliage-gleaner is 20 to 21 cm (7.9 to 8.3 in) long and weighs 44 to 51 g (1.6 to 1.8 oz). It is a largish furnariid with a long almost straight bill. The sexes have the same plumage. Adults have a chestnut face with a light rufous moustacial area. Their crown is chestnut that becomes a slightly paler reddish chestnut collar and a rich ochraceous brown back and rump. Their uppertail coverts are chestnut. Their wings are mostly dark rufous and their tail chestnut. Their throat is pale rufous that becomes slightly darker on their breast and belly. Their flanks are darker rufescent brown and their undertail coverts reddish-rufous.Their iris is sulphur-yellow, their bill dark gray with a paler base to the mandible, and their legs and feet grayish.

行为
The henna-capped foliage-gleaner is a year-round resident throughout its range.<p>The henna-capped foliage-gleaner feeds on arthropods. It forages mostly by itself or in pairs and is thought to occasionally join mixed-species feeding flocks. It is mostly terrestrial and gleans its prey from the ground and leaf litter.<p>The henna-capped foliage-gleaner is assumed to be monogamous. It makes a nest of dry grass and leaves in a tunnel it excavates in an earthen bank. Nothing else is known about its breeding biology.<p>The henna-capped foliage-gleaner's call is a "dry, cackling 'kjep -kjep - -". Its song is like the call "but accelerating to a rattle, in total lasting 2-3 sec."

White-browed Crombec
Sylvietta leucophrys
Small, virtually tailless warbler of montane forest. The facial pattern is distinct, with a rufous-brown cap and eye-stripe and a contrasting white eyebrow and throat. Found in thick areas of montane humid forest, especially tangled undergrowth and vines. Sometimes joins mixed-species flocks. The song is a quiet series of up-and-down twitters. Chapin’s Crombec is very similar, but White-browed is easily separated by its broad white eyebrow.
Semipalmated Sandpiper
Calidris pusilla
Small, grayish-brown sandpiper. Typically shows relatively short, blunt-tipped bill, but this varies across the breeding range: western populations are shortest-billed, eastern populations are longest, and females have longer bills than males! Also note blackish legs, although they can appear dull gray or greenish. In breeding plumage, fairly pale grayish brown, sometimes with brighter rusty cap and cheek. Nonbreeding is plain gray above and white below. Juveniles have attractive scaly pattern on upperparts, and variable coloration: usually grayish with some buffy areas, occasionally brighter rufous. Most similar to Western and Least Sandpipers. Western averages slightly larger and longer-billed, with brighter rufous on breeding adults and juveniles; nonbreeding birds paler but extremely similar to Semipalmated. Least Sandpiper is darker and browner. Breeds on high Arctic tundra. Migrates to South America for the winter; very rarely lingers in the U.S. past November, unlike Western Sandpiper. Usually found in flocks, sometimes in very large numbers. Prefers open mudflats, but also found in marshes and beaches.
Tinian Monarch
Monarcha takatsukasae
Mostly rusty-red below and around the face, with a gray cap and a brownish back. Tail black with white tips, and wings have clear white double wingbars. Undertail white. Found in any forested habitat and dense scrub. Song is a short whistled “tee-tee-wheeeooo.” Common calls include mostly low rasping and scolding.
