Yellow-eyed Junco
Junco phaeonotus
This distinctive sparrow is common in open montane woodland usually dominated by pine. Primarily a Mexican species, barely enters U.S. Much like Gray-headed and Red-backed subspecies of Dark-eyed Junco but with staring yellow eye and rufous back usually extending onto wings. Otherwise pale gray, darkest around the eye. Bill half black, half yellow. White outer tail feathers like Dark-eyed Junco. Forages on the ground, but perches higher when singing. Song has a similar ringing tone to Dark-eyed Junco, but usually with several distinct sections of chips and trills.
Taxonomy
The yellow-eyed junco was formally described in 1831 by the German naturalist Johann Georg Wagler from a specimen collected in Mexico. He introduced a new genus, Junco, and coined the binomial name Junco phaeonotus. The genus name is from Latin iuncus meaning "rush". The specific epithet combines the Ancient Greek phaios meaning "dusky" or "brown" with -nōtos meaning "-backed".<p>Four subspecies are recognised:

Olive-backed Pipit
Anthus hodgsoni
Small pipit with a greenish-brown back and heavily streaked breast and belly that is often seen in loose flocks or in pairs. Note the distinctive facial pattern: broad pale lines surrounding the eye and a dark ear patch. Prefers more forested areas than other pipits, though will also forage in fields and scrubby edges. Can be tolerant of human activity and is not uncommon in rural areas and city parks in parts of their range. Calls are high-pitched “tseep’s,” often with a buzzy quality. Song is a beautiful series of warbling trills, whistles, and rattles.
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.
Green-throated Mango
Anthracothorax viridigula
Large, dark hummingbird found in coastal regions and along large rivers. Use caution eliminating the more widespread Black-throated Mango, which often occurs in the same habitats; female-plumaged birds in particular may not be safely separable. Found in mangroves, abandoned plantations, swampy forests, and urban areas, often at higher levels in flowering trees, where it feeds on nectar and hawks for tiny flying insects. In proper light, green throat of male is diagnostic. Tail color is useful if bird can be studied at length; Green-throated’s tail is mostly purple, with brownish central tail feathers (tail of Black-throated is more chestnut, but subject to variation depending on light).
