Yellow-headed Warbler
Teretistris fernandinae
A gregarious resident of dense tangles and thickets in otherwise open habitats; not found in dense forest or mangroves. The gray body contrasts sharply with its yellow head, but note that some birds have yellow on the chest as well. Prothonotary Warblers are somewhat similar, but are mostly yellow below with a green (not gray) back. Pine Warblers have a green back, white wingbars, and are usually more extensively yellow below. Song is a series of raspy buzzy notes. Call notes similar to song, but are given singularly or without pattern.
识别特征
The yellow-headed warbler is about 13 cm (5.1 in) long and weighs 6 to 18.5 g (0.21 to 0.65 oz). Its entire head is yellow, with an olive tinge on the crown and nape. Its upperparts are gray and its underparts a lighter grayish white.
分类信息
The yellow-headed warbler shares its family and genus with the Oriente warbler (T. fornsi). They were originally placed in the New World warblers (Parulidae) but phylogenetic studies of nuclear and mitochondrial DNA led to reassessment of several genera and in 2017 the Cuban warblers were moved to their own family. Their closest relatives are the four members of family Spindalidae, the yellow-breasted chat (Icteria virens), and the New World blackbirds of family Icteridae.<p>The yellow-headed warbler is monotypic.

分布与栖息地
The yellow-headed warbler is found in far western mainland Cuba, Isla de la Juventud (Isle of Pines), and the nearby Cayo Cantiles. It inhabits all available forest types as long as they have a relatively undisturbed understory, and also scrubby thickets in drier areas. In elevation it ranges from lowlands to high mountains.

行为
The yellow-headed warbler is a year-round resident throughout its range.<p>The yellow-headed warbler forages from the ground to the forest mid-level, gleaning rocks and foliage for insects and other invertebrates. It is also believed to take small lizards. It often forages in flocks.<p>The yellow-headed warbler's breeding season is from March to July, with eggs laid in April and May. It makes a cup nest of grass, rootlets, and other plant fibers and usually places it fairly low in a bush, vine, or sapling. The clutch size is two or three eggs. The incubation period and time to fledging are not known.<p>The yellow-headed warbler's song is "a series of buzzy grating notes interspersed with sweeter, more musical notes". Its calls include "a rapid, high-pitched, staccato chattering" and "various other buzzy and grating notes".

Transvolcanic Jay
Aphelocoma ultramarina
Rather large, blue-and-gray jay of highland pine and pine-oak forest endemic to highlands of central Mexico; occurs in transvolcanic belt from Volcánes de Colima in the west to Volcán Orizaba in the east. Typically travels in wide-ranging flocks of 5–25 birds, mainly at middle to upper levels in trees. Appreciably larger and broader-winged than Woodhouse's Scrub-Jays, with plainer plumage (lacks dark mask, whitish eyebrow, and partial dark collar of Woodhouse's Scrub-Jay). Noisy calls carry well.
Short-tailed Parrot
Graydidascalus brachyurus
Medium-sized, uniformly bright green parrot with a short tail. Note the indistinct black eye-line, the dusky bill, and the darker green flight feathers; other parrots have more colorful plumage and longer tails. Inhabits seasonally flooded forest along large rivers, occasionally venturing into adjacent urban areas.
Andean Goose
Oressochen melanopterus
This chunky white-and-black goose is often common and conspicuous on Andean bogs and lakeshores; usually in pairs or small groups and can be confiding in areas where not hunted. Note the small pink bill and pink legs; sexes alike but the male is larger. Local overlap in Andes of central Chile with Upland Goose. Male Upland Geese have a black bill and legs, and dark barring on body. Like the other species in this genus, males give high wheezy whistles whereas females grunt and bray.
