Rose-throated Becard
Pachyramphus aglaiae
Rather chunky, big-headed bird with a bushy crest. Male varies from pale gray (in drier areas) to dark slaty gray (in rainforest); pink throat patch absent in darkest rainforest birds. Female also variable, but always has bushy blackish cap. Young male looks like female with variable pink on throat. Widespread in tropical and subtropical areas in Middle America, also locally in the highlands. Favors woodland and forest edge, but also found in brushy fields, hedgerows, and most habitats with a scattering of larger trees; often at fruiting trees. Feeds rather sluggishly, often craning its head back and forth deliberately.
识别特征
The most distinguishing characteristics of this bird is the rose-colored neck bib found in adult males. Males are mostly gray in color, with a contrasting darker upperside and a pale gray underside. Males also show a black crown. Females are mostly brown in color, with a rusty brown upper side, and a pale buffy underside. The crown is a dark gray, not nearly as stunning as the males. Its usual call is a mournful "seeeeuuuwww".[citation needed]
分类信息
The classification of the rose-throated becard was long controversial, with taxonomists arguing either that it was a cotinga or a tyrant flycatcher. However, genetic evidence indicates that it is in a separate family altogether.

分布与栖息地
Rose-throated becards usually occur in riparian areas of pine-oak woodlands and evergreen forest. They breed from south-easternmost Arizona and extreme southern Texas of the United States to western Panama. Breeding is local and sporadic in the US, and becomes more regular in Mexico. Birds are normally permanent residents, but birds found in the United States generally migrate for the winter.

行为
Most breeding activity runs from May to July, but the season may be delayed at high elevation. They make a domed, pendulous nest that hangs from a high tree branch. Three to six eggs are laid, with great variation in color including off-white, light purple, olive, and pinkish. Eggs have scrawling, spotted, markings at the larger end.<p>The becard feeds primarily on insects, which it will glean from the vegetation, but captures some in flight as well. They will also take berries and seeds.

Savanna Nightjar
Caprimulgus affinis
Well-camouflaged nightbird, usually encountered roosting on gravel riverbeds, open areas in grasslands, rooftops, or roadsides. Sometimes found in small loose flocks when roosting. Fairly well adapted to urban life in some parts of its range and often found in towns and city edges. Intricately patterned gray-brown with less white than other nightjars; only males have a fairly small white patch on the wing near the tip. Most often detected by its distinctive, high-pitched, burry “chree-ik” song, repeated over and over.
Cinnamon Flycatcher
Pyrrhomyias cinnamomeus
Bright rufous flycatcher of the Andean subtropical zone. Fairly small size, entirely cinnamon underparts, brown back, and bright rufous wing patch render this species distinctive. Usually found in pairs, perched conspicuously at the edge of the cloud forest. Sexes alike. Voice is also a good way to detect this species: listen for the sputtering, slightly descending trill. The subspecies found in Venezuela and northern Colombia is even brighter cinnamon than its southern counterparts, especially on the back and wings.
Yellow-bellied Chat-Tyrant
Silvicultrix diadema
Small flycatcher found in subtropical and temperate zones of the Andes from Venezuela to Peru. Like most chat-tyrants, has a very bold eyebrow. Yellow-bellied is the only chat-tyrant that looks mostly yellow and is especially bright on the belly and throat. Note rufous wingbars. Singles or pairs are typically found in the understory of cloud forest and edges, especially near bamboo, but can be inconspicuous.
