Rufous Motmot
Baryphthengus martii
Large forest-dweller that likes to sit motionless. Head and breast rufous-orange with black mask and breast spot. Green back and long tail. Most similar to smaller Broad-billed Motmot; note larger size, rufous chin, and more extensive rufous on belly. Often found singly or in pairs inside forest, usually below canopy. Listen for deep hooting call, “woo-doop”, sometimes given as a single call or sometimes as ongoing hooting laughter.
识别特征
The rufous motmot is the second-largest member of its family. The male of the nominate subspecies is 42 to 47 cm (17 to 19 in) long and weighs 146 to 160 g (5.1 to 5.6 oz). The female weighs 153 to 173 g (5.4 to 6.1 oz). Male and female B. m. semirufus weigh 185 to 193 g (6.5 to 6.8 oz) and 170 to 208 g (6.0 to 7.3 oz) respectively. Adults are mainly cinnamon-rufous, with a black face mask and central breast spot, green wings and sides, a greenish-blue lower belly, and dark blue tail and flight feathers. The tail is very long, and that of B. m. semirufus but not the nominate has a bare-shafted racket tip. The bill and legs are black. Young birds are paler and duller than adults, and lack the tail rackets and black breast spot.
分类信息
The rufous motmot and rufous-capped motmot (Baryphtengus ruficapillus) are the only two species in their genus, and have sometimes been treated as conspecific and apparently form a superspecies. The rufous motmot has two recognized subspecies, the nominate Baryphthengus martii martii and B. m. semirufus. In the early 20th century, B. m. martii was classified in its own genus, Urospatha. Later, the Nicaraguan and Costa Rican populations were considered to be a third subspecies, B. m. costaricensis, but it was decided they were part of B. m. semirufus. The binomial commemorates the German botanist and explorer Carl Friedrich Philipp von Martius.[citation needed]

分布与栖息地
The nominate subspecies of rufous motmot occurs in the western Amazon Basin in southeastern Colombia through eastern Ecuador and Peru to northern Bolivia, and east into western Brazil. The range of B. m. semirufus is separate from that of the nominate. It occurs from eastern Honduras through the Caribbean slopes of Nicaragua, Costa Rica, and Panama, and continues on the Pacific slope of Panama into northwestern Colombia and western Ecuador. In elevation it ranges from near sea level to 1,250 m (4,100 ft) in Costa Rica and to 1,400 m (4,600 ft) in Panama and Ecuador. In Peru it can be found locally to 1,600 m (5,200 ft) but more generally to 1,300 m (4,300 ft).<p>The rufous motmot inhabits humid lowland evergreen primary forest and also secondary forest. It prefers tall forest, especially along rivers and streams, but avoids dense foliage.

行为
The rufous motmot is omnivorous. It has been documented eating many types of fruit, adult insects and their larva, arachnids including crustaceans, and small fish, lizards, and frogs.<p>The rufous motmot's breeding and nesting phenology has few reported details. It is assumed to nest in deep burrows in earthen banks like other motmots. The clutch size and eggs are undescribed. <p>The rufous motmot's song has been described as "hoos, hoots, or hoops" [1]. It is sometimes answered by a low owl-like hoop hoop huhuhuhuhuhu [2]. An agitation call is a dry chatter [3].

Undulated Antshrike
Frederickena unduliger
Magnificent dark antshrike of mature upland rainforest. Has a large head with a crest and strongly hooked bill. Males are slaty gray with fine black barring; females are tawny orange with fine black barring. Larger than most other antshrikes and antbirds in its range. Forages singly or in pairs in open understory, and seems to be somewhat rare throughout its range. Its song is a gradually rising series of low whistles given at a steady pace.
Apical Flycatcher
Myiarchus apicalis
Medium-sized, dull flycatcher without many distinguishing features; typical of the genus Myiarchus. This species is restricted to Colombia, where it is found in dry woodland and scrubby habitat below 1700m. Generally brownish above with pale gray throat fading to lemon yellow belly. Crown is fairly dark brown. Look especially for the pale tips on the tail feathers to separate from similar species. Listen for dry ‘whit’ calls.
Bryan's Shearwater
Puffinus bryani
Smallest known shearwater. Tiny, black and white shearwater with rapidly fluttering wingbeats and an entirely white face. Little is known about this species, though it differs from the very similar Rapa Shearwater by having a black undertail, shorter tail and being paler grayish black.
