Lanceolated Monklet
Micromonacha lanceolata
Small puffbird, always rare in the middle levels of lowland and foothill forest. Typical puffbird shape: rotund with a large flat head and thick hooked bill. Brown above and white below with heavy blackish streaking. Unlikely to be mistaken. Easy to overlook as it perches quietly, often around a clearing or edge within forest. Usually single or in pairs, occasionally associating with a mixed-species flock. Listen for rising whistled calls.
识别特征
The lanceolated monklet is 13 to 15 cm (5.1 to 5.9 in) long and weighs 19 to 22 g (0.67 to 0.78 oz). It is entirely warm brown with scale-like buffy markings above. It has white bristles around the base of the large bill, and white "whiskers", which are actually tufts of feathers. Its lores and a half ring behind the eye are white. The wings and the top side of the tail are dark brown and the tail's underside is gray. Most of its underparts are white with heavy black streaks; the center of the belly is unstreaked and the vent area has an ochre tinge.
分类信息
The lanceolated monklet is the only member of its genus, and the only bird called a "monklet". It has no subspecies, though the population in Costa Rica and western Panama has been discussed as possibly being one.

分布与栖息地
The lanceolated monklet is found in several disjunct areas. One is the Caribbean slope in Costa Rica and into west central Panama. Another extends from west central Colombia south to west central Ecuador. The largest area includes eastern Ecuador, southern Colombia, western Brazil, and eastern Peru. It is also found in a few locations in Bolovia. It inhabits a variety of landscapes including the edges and natural clearings of primary and mature secondary forest, small forest patches, shade coffee plantations, and lowland and montane evergreen forest. It tends to occur in the mid- and upper vegetation levels. In elevation it mostly occurs between 300 and 1,500 m (980 and 4,900 ft) but can be found as high as 2,100 m (6,900 ft).

行为
The lanceolated monklet hunts from a perch, typically 4 to 8 m (13 to 26 ft) above the ground, and sallies from it for its insect prey. Its diet also includes berries. It sometimes follows mixed-species foraging flocks.<p>One lanceolated monklet nest was in a chamber at the end of a 40 cm (16 in) long tunnel in an earthen bank. The clutch of two white eggs was laid on dry leaves.<p>The lanceolated monklet's song is "1–5 high, thin, plaintive rising whistles, 'sewee ... sewee sewee-sewee-sewee’swee’swee', each slightly higher than preceding one". Its contact call is a "thin, high-pitched 'tsip tsip'".

Least Grebe
Tachybaptus dominicus
This wee little grebe is dark gray overall with paler fluffy bum. The face is dark in breeding plumage; paler with a whitish throat in nonbreeding plumage. Also note piercing yellow eye and thin, sharply pointed bill. Compare with Pied-billed Grebe, which is larger, browner, and thicker-billed. Widespread throughout Middle and South America; very limited range in the U.S. Found in marshy ponds, often with extensive vegetation. Usually seen singly or in pairs, sometimes in small groups. Frequently dives underwater.
Lesser Greenlet
Pachysylvia decurtata
Small plain vireo of tropical forest and woodland in lowlands. Usually stays fairly high in trees and likely to be overlooked unless its rather tuneless, monotonously repeated song is learned. Identified by a combination its gray head (in Mexico and Central America) with a diffuse whitish eyering; whitish underparts with a yellowish wash on the sides; and plain olive upperparts. Head of birds from eastern Panama to South America is olive, with a whitish eyering.
Damara Tern
Sternula balaenarum
A very small, short-tailed tern of coastal waters. It often flies slowly on rapidly-beating wings with its head angled downwards, before hovering and plunge-diving to catch small fish. When breeding, it has a complete black skull cap and bill; when not breeding the front of the forehead turns white. It breeds on barren gravel plains and dunes but is most frequently encountered foraging over estuaries, lagoons, and near shore. Its strident “tsit-tsit” call is higher-pitched than those of other terns. In non-breeding plumage, the very similar Little Tern has contrasting paler rump and tail, while Damara Tern’s back, rump, and tail are all the same shade of pale gray.
