Golden-cheeked Woodpecker
Melanerpes chrysogenys
Common in tropical lowlands of west Mexico, where it is endemic. Found in woodlands, coconut plantations, gardens, and semi-open areas with taller trees, including towns and villages. Often noisy and conspicuous; calls include a sneezy "cháco cháco." Golden wash to cheeks is inconspicuous, but big black eye patch is diagnostic among similar "ladder-backed" woodpeckers. Male has flame-red crown patch and female has pale grayish crown.
识别特征
The golden-cheeked woodpecker is about 19 to 22 cm (7.5 to 8.7 in) long and weighs 55 to 88 g (1.9 to 3.1 oz). The sexes' plumage is alike except for their head pattern. Adult males of the nominate subspecies have a whitish forehead, a red crown, and a yellow-gold nape and hindneck. Adult females have the same whitish forehead but a grayish-buff crown and an orange-red nape. In both sexes a wide black area surrounds the eye. Their upperparts are barred black and white; the black is widest on the rump and uppertail coverts. Their flight feathers are black with white bars throughout. Their tail is black with white bars on the central pair of feathers and progressively more white on each pair out from them. Their lores and under the eye are deep golden-yellow and their cheeks, chin, and throat are golden-buff. Their underparts are mostly gray-brown to brownish-buff with a strong olive-yellow wash and a yellowish orange patch on the central belly. Their lower flanks and undertail coverts are grayer with dark bars. Their bill is longish and black, their iris is reddish to orange-brown, the bare skin around the eye blackish, and the legs green-gray. Juveniles have grayer or browner upperparts with less contrasting barring than adults, and paler and grayer underparts with a strong yellow cast and obscure bars. Both sexes have red on their crown but females less than males and often more black. Subspecies M. c. flavinuchus is slightly larger and duller than the nominate, has less yellow on its face and yellow instead of red on its hindneck, and has grayer underparts.

分布与栖息地
The nominate subspecies of golden-cheeked woodpecker is found in western Mexico between Sinaloa and Nayarit. M. c. flavinuchus is found from Jalisco in west central Mexico south along the coast to Oaxaca and east to Puebla. The species inhabits the interior and edges of mesophytic to xeric forest and more open landscapes like patches of forest, savanna with trees, and plantations. In elevation it ranges from sea level to about 1,500 m (4,900 ft).

行为
The golden-cheeked woodpecker is a year-round resident throughout its range.<p>The golden-cheeked woodpecker feeds both on insects like ants and adult and larval beetles, and also on fruits and seeds. It forages on trees from their middle to upper levels, singly or in pairs, and gleans, probes, and pecks for its food.<p>The golden-cheeked woodpecker's breeding season is from May to July. It excavates its nest hole in a tree or cactus. Nothing else is known about its breeding biology.<p>The golden-cheeked woodpecker makes a variety of vocalizations including a "nasal 'ki-di-dik'", a "loud, nasal 'cheek-oo, cheek-oo, cheek-oo, keh-i-heh-ek'" and a "softer 'keh-i-heh' or 'kuh-uh-uh'."

White-throated Fantail
Rhipidura albicollis
A distinctive fantail, all dark except for a white throat and a short white eyebrow. The tail, often fanned, is a shade darker with white tips to all tail feathers except the central pair. Juvenile is like adult, but with reduced white on face and brownish edges to the dark body feathers. Gives very harsh contact calls. Song is a musical phrase of 6-7 notes that ascends first and then descends. Found in a wide range of wooded habitats, from dense forest to forest edge and gardens, from lowlands up into the mountains.
Gurney's Eagle
Aquila gurneyi
A large raptor which soars over lowland and foothill forest and disturbed areas. A dark, stately eagle with long wings, long tail, pale patches at the base of the flight feathers. The wings are held flat in flight and feathers are ‘fingered’ at the wing tips. Similar to Wedge-tailed Eagle, with which it doesn’t normally co-occur, but Gurney’s Eagle has a long, rounded tail rather than a wedge-shaped tail. Call described as a high-pitched downslurred note.
Stripe-backed Bittern
Botaurus involucris
Very small, striped buffy heron of wetlands and lake edges with dense reeds and rushes. Boldly striped back pattern is distinctive. In flight shows contrasting broad rusty trailing edge to wings. Usually seen as single birds hidden in reeds or making short flights low over reeds or across patches of open water. Clambers easily and stealthily; hunts from perches over water, where sits patiently before stabbing at fish. Mostly silent.
