Chestnut-headed Nunlet
Nonnula amaurocephala
Small puffbird with a large head and bill. Uncommon and rarely encountered, restricted to a small area along the Amazon river in central-western Amazonia. Typically found in the understory of dense, shaded flooded forests. Plumage is mostly a uniform rufous-brownish, with darker brown wings and upperparts.
Identification
The chestnut-headed nunlet is 14 to 15 cm (5.5 to 5.9 in) long and weighs 15 to 16 g (0.53 to 0.56 oz). Its entire head, upper mantle, breast, and upper belly are bright rufous. Its back, wings, and tail are plain dull brown; the rump has an olive wash. The rufous upper belly grades to whitish on the lower belly. The bill is mostly black, the eye red, and the feet lead gray.
Taxonomy
The chestnut-headed nunlet is monotypic. It, the rufous-capped nunlet (N. ruficapilla), and the grey-cheeked nunlet (N. frontalis) form a superspecies.

Western Sandpiper
Calidris mauri
Small sandpiper with relatively long, droopy bill (longer on females). In breeding plumage, shows rich rufous tones on shoulders, cheeks, and crown. Nonbreeding is plain pale gray above and white below. Juveniles look pale-faced and have a bright strip of rufous feathers on the upper edge of the wings. Most similar to Semipalmated Sandpiper, which averages shorter-billed and duller grayish-brown overall. Extremely difficult to distinguish in winter; note Western is somewhat larger-headed and more front-heavy. Droopy bill might recall Dunlin, but Western is smaller and paler. Breeds on high Arctic tundra in Alaska. In migration and winter, occurs in large flocks on mudflats and beaches. Much more common in western North America; uncommon to rare on the east coast. Occurs in the winter in the U.S., unlike Semipalmated Sandpiper; regularly winters as far south as Peru, rare to Chile.

Visayan Blue-Fantail
Rhipidura samarensis
A fairly small, long-tailed bird of lowland and foothill forest on Bohol, Leyte, and Samar islands. Overall dull blue in color with a paler belly. Often pumps tail up and down. Forages in the understory for insects and often joins mixed-species flocks. Similar in size and shape to Celestial, Short-crested, and Black-naped Monarchs, but darker blue with a contrasting pale blue brow, tail, and wing patch. Song is a slightly ascending series of medium-pitched, upslurred whistled notes, increasing in volume. Also gives a nasal, buzzing “gew!”

Keel-billed Motmot
Electron carinatum
Medium-sized forest-dweller that likes to sit motionless. Mostly dull green, slightly buffier below, with black mask and breast spot. Orange forehead and blue eyebrow and chin are distinctive. Most similar to larger Lesson’s Motmot; note smaller size and face pattern. Often found singly or in pairs inside forest, usually below canopy. Never common; quite inconspicuous and can be difficult to find within its limited range. Call very similar to Broad-billed Motmot.
