Veracruz Wren
Campylorhynchus rufinucha
Large wren occurring locally in a small area on the Gulf Coast of Veracruz. Usually found in small groups, less often in pairs. Mainly found in semi-dry scrubby habitats. Note boldly barred wings and tail and rufous back and nape patch. Only large wren in range. Often detected by its marvelous loud song, often given by multiple birds at once, which consists of various nasal and whistled notes, with some harsh elements mixed in.
识别特征
The adult Veracruz wren has a blackish crown, lores, and eyestripe and a white supercilium. Its nape and back are chestnut and the shoulders have black and white streaks. Its tail is gray-brown with darker bars and a white tip. Its chin and throat are white, the chest pale buff with brown spots, and its belly a darker buff with faint blackish bars on the flanks. The juvenile is similar but its supercilium is buffy white, the back a duller cinnamon, and the markings on the back less distinct.
分类信息
What is now the Veracruz wren was previously treated as one of eight subspecies of rufous-naped wren (that carried the binomial Campylorhynchus rufinucha). A 2009 publication proposed that Campylorhynchus rufinucha (sensu lato) be split into three species and the International Ornithological Committee (IOC) accepted the splits. Because the binomial C. rufinucha (sensu stricto) had scientific priority, it received the new English name Veracruz wren. What had been C. r. humilis was elevated to species status as Sclater's wren and the other six subspecies became subspecies of C. capistratus, the rufous-backed wren.<p>BirdLife International (BLI) has implemented the split but retains the English name rufous-naped wren for C. rufinucha. However, the North American Classification Committee of the American Ornithological Society (NACC/AOS) and the Clements taxonomy have not accepted the split as of early 2021.

Western Kingbird
Tyrannus verticalis
Fairly large yellow-bellied flycatcher; common and widespread in western North America. Rather pale gray head with weakly contrasting whitish throat and breast, and lemon-yellow belly. Also look for black tail with white edges (but this can be difficult to see, especially when worn). Found in open habitats with tall shrubs and trees, often perched up conspicuously on a telephone wire or fence post. Compare especially with Cassin’s Kingbird, which is darker and more contrasting on the head. Winters in large numbers south to Costa Rica, often gathering in large loose groups during migration.
Surucua Trogon
Trogon surrucura
Often draws attention to its presence by its song: an ascending sequence of “kwa” notes, similar to Green-backed Trogon, but faster. Two subspecies occur in Brazil, Paraguay, and northeastern Argentina with limited geographical overlap that vary in the color of the breast and eyering; the southern one has a red belly and eyering, while the northern one has a yellow belly and eyering. The males of both subspecies have a violet-blue head and breast, a green back, and a white undertail. Females have a dull gray breast and the undertail is gray with white tips. Found in the middle to upper levels of forests and woodlands.
White-fronted Wattle-eye
Platysteira albifrons
A cute and dumpy black, gray, and white flycatcher-like bird with striking red eye-wattles and white wing-stripes. The sexes differ: male has a broad black chest band and dark gray upperparts; female has completely white underparts and is duller gray above. Juvenile browner, lacking eye-wattles. Pairs are resident, flitting around the middle canopy of dry thickets, gallery forest, and mangroves in coastal northwest Angola and the adjacent Democratic Republic of Congo. Calls include a repeated grating “grrrrt-grrrt-grrrt” interspersed with clicks and buzzing notes, similar to other wattle-eyes. Black-thrated Wattle-eye marginally overlaps in the north of White-fronted Wattle-eye’s range, but it differs by the male being darker above and lacking white above the bill, and by the female having a brown throat.
