Tropical Royal Flycatcher
Onychorhynchus coronatus
Uncommon, medium-sized, overall warm brown flycatcher of humid tropical forest in lowlands. Note the hammerhead crest—very rarely fully raised to reveal spectacular, flame-red fan with violet-blue-black tips. Otherwise looks rather flat-headed. Also note the long bill, and pale cinnamon rump and tail. Usually found as singles or pairs in mid-levels of dense forest, where flutters actively after insects. Nest is a straggly mass of dead vegetation up to 3 feet long that hangs from the tip of a branch, often along streambeds. Often detected by single squeaky calls; rarely-heard song variable across range. Occurs from Mexico to Brazil.
识别特征
The tropical royal flycatcher is approximately 12.5 to 18 cm (4.9 to 7.1 in) long and weighs 9.7 to 21 g (0.34 to 0.74 oz). It has an erectile fan-shaped crest. In the nominate subspecies O. c. coronatus it is red with blue tips in the male and yellow or orange in the female. The sexes' plumages are otherwise alike. Adults have a broken buffy eye ring and a faint buffy streak on the cheek. Their upperparts are dark brown with narrow black and buffy bars on the lower back. Their rump and tail are cinnamon-rufous that is browner towards the end of the tail. Their wings are dark brown with small buff spots on the tips of the coverts and tertials. Their throat is whitish, their breast warm buff with narrow black bars, and their belly plain warm buff. Their iris is various shades of brown, their maxilla dark brown to blackish, their mandible horn to yellowish or orange, and their legs and feet dull yellow or orangish.<p>Subspecies O. c. castelnaui is very like the nominate, though slightly smaller and with less barring on the back. O. c. mexicanus is the largest subspecies. Its upperparts are not as dark as the nominate's, its tail more rufous, its chin and throat white, and its breast has less barring. O. c. fraterculus is slightly smaller than mexicanus, with a paler cinnamon rump and tail and even less barring on the breast. O. c. occidentalis is about the same size as fraterculus. It is mostly bright buffy brown, with a pale tawny tail and an unmarked breast. The male's crest is more red than the nominate's orange, with black tips.

The tropical royal flycatcher was formally described in 1776 by the German zoologist Philipp Statius Müller under the binomial name Muscicapa coronata. Müller based his account on a hand-colored illustration of the "Tyran hupé de Cayenne" that had been engraved by François-Nicolas Martinet. The specific epithet is from Latin coronatus meaning "crowned". The tropical royal flycatcher is now placed together with Atlantic royal flycatcher in the genus Onychorhynchus that was introduced in 1810 by the German naturalist Gotthelf Fischer von Waldheim.<p>For many years the IOC considered the Amazonian royal flycatcher and three other royal flycatcher taxa to be separate species. In 2024 the IOC combined ("lumped") the northern, Amazonian, and Pacific royal flycatchers as this article's single species, the tropical royal flycatcher, and left the Atlantic royal flycatcher (O. swainsoni) unchanged.<p>Other taxonomic systems differ in their treatment of the royal flycatchers. BirdLife International's Handbook of the Birds of the World (HBW) retains the four-species treatment that IOC abandoned. Through 2022 the Clements taxonomy treated the northern, Amazonian, Pacific, and Atlantic taxa as a single species, the royal flycatcher. In 2023 Clements split the Atlantic from it and renamed the remainder the tropical royal flycatcher, achieving somewhat earlier the same two species as the 2024 IOC change. However, Clements places them in family Oxyruncidae, rather than in Tityridae like the IOC.<p>The North American and South American Classification Committees of the American Ornithological Society (AOS) recognize one royal flycatcher, just as Clements did until 2023, but place it in family Onychorhynchidae. The South American committee is seeking a proposal for reevaluation of the taxa.<p>The IOC and Clements recognize these five subspecies of the tropical royal flycatcher:<p>Subspecies O. c. mexicanus and O. c. occidentalis have sometimes been treated as separate species.

分布与栖息地
The subspecies of the tropical royal flycatcher are found thus:<p>The tropical royal flycatcher inhabits humid lowlands, both primary evergreen and second growth forests. It is a bird of the lower levels and midstory, often along streams and in seasonally flooded várzea forest. In elevation it ranges from sea level to 1,200 m (3,900 ft) in much of Central America and Colombia though lower in Costa Rica. In Brazil it occurs below 1,000 m (3,300 ft), in eastern Ecuador below 400 m (1,300 ft), and in western Ecuador below 600 m (2,000 ft)

Gray Tinamou
Tinamus tao
Very large chicken-like bird, widespread across the Amazon basin, but nowhere common. Distinguished from other tinamous by entirely gray plumage with fine black barring on the upperparts and some white speckling on the head. Gray Tinamou is also larger than other large species such as Great and White-throated Tinamous. Favors areas of upland forest and is most often encountered by voice, a single, short hollow whistle given at long intervals.
Olive-backed Foliage-gleaner
Automolus infuscatus
Dark brown foliage-gleaner of mature rainforest understory. Warm dark brown body, with a clean whitish throat patch and reddish brown tail. Does not have prominent reddish brown in the wings like many other foliage-gleaners do; the clean whitish throat, plain face (without a strong eyebrow) and habit of foraging low are other good distinguishing features to tell it apart from other foliage-gleaners. Primarily found in the understory of mature rainforest. Listen for its song, a musical trill with stuttered introductory note, “ch-trrrrrrrr”, similar to that of Chestnut-crowned Foliage-gleaner from denser secondary growth habitats, but slightly lower and with a more distinct introductory note.
Ultramarine Grosbeak
Cyanoloxia brissonii
Stunning dark blue bird with a huge bill. Male is mostly deep cobalt with paler highlights on the shoulder and eyebrow and a darker patch around the eye. Female is rich reddish-brown overall. Found singly or in pairs in scrubby wooded habitats, often near water. Can be skulky, preferring to forage in dense thickets. Occurs mostly in southeastern South America, with disjunct populations in Venezuela and Colombia. Compare with Blue-black Grosbeak, which doesn’t overlap much in range and is typically found in heavier forest.
