Streaked Flycatcher
Myiodynastes maculatus
Large, streaky flycatcher, summer migrant in northern part of its range. Favors forest and edge, plantations with tall trees; lives mainly at middle to upper levels in the canopy. Told from slightly smaller and slimmer Sulphur-bellied by paler throat, lack of thick blackish moustaches, lack of strong yellow wash on belly, and bigger bill with pale pinkish base below (can be matched by juvenile Sulphur-bellied).
识别特征
The streaked flycatcher is 22 cm (8.7 in) long, weighs 43 g (1.5 oz) and has a strong black bill. The head is brown with a concealed yellow crown patch, white supercilium and dusky eye mask. The upperparts are brown with darker brown streaks on the back, rufous and white edges on the wings, and wide chestnut edges on the rump and tail. The underparts are yellowish-white streaked with brown.<p>Sexes are similar, but immature birds are brown where the adult is black. M. m. solitarius has black rather than brown streaking above and below. The streaked flycatcher is a conspicuous bird, with a noisy sqEEE-zip call.<p>It is very similar in appearance to the less widespread sulphur-bellied flycatcher. The streaked flycatcher has a heavier bill, lighter yellow belly, pink basal half of the lower mandible and creamy (not white) superciliary.

分布与栖息地
This species breeds from eastern Mexico, Trinidad and Tobago south to Bolivia and Argentina. The southern subspecies M. m. solitarius migrates to Venezuela and the Guianas from March to September during the austral winter. It is found at the edges of forests and cocoa plantations. Common across its wide range, this species is not considered threatened by the IUCN.

行为
Streaked flycatchers eat a range of food items, mostly large insects (such as cicadas, locusts and beetles), but also lizards and berries. It perches on a high watchpoint from which it sallies forth to catch insects in mid-flight or off plants using a range of aerobatic maneuvers, and occasionally gleans prey from the vegetation. The wintering southern migrants seem to include a considerable amount of fruit in their diet, for example those of Tamanqueiro (Alchornea glandulosa) which they sometimes eat in quantity; fruit are typically ripped off in mid-hover. It occasionally follows mixed-species feeding flocks, pouncing from up in the trees on prey flushed by birds in the undergrowth.<p>The nest is an open cup of twigs and grasses placed in a tree hollow or sometimes a bromeliad. The female builds the nest and incubates the typical clutch of two or three creamy-white eggs, which are marked with red-brown spots, for 16–17 days to hatching. Both sexes feed the chicks, which fledge in a further 18–21 days.

White-fronted Swift
Cypseloides storeri
Poorly known and rarely seen medium-sized swift. Very local in west Mexico and very rarely identified in the field. Like many swifts, nests behind waterfalls. Rather stocky and large-headed, with a squared tail tip. About the same size as much commoner Chestnut-collared Swift, with which White-fronted can associate. Plumage looks wholly black unless seen close in good light, when white forehead can show up. Beware, slightly larger Black Swift has similar white forehead.
Pacific Baza
Aviceda subcristata
Conspicuous medium-sized hawk with broad paddle-shaped wings that pinch in close to the body. When perched it is easily distinguished from other species by small black crest on the back of gray head and enormous yellow eyes, prominent brown stripes on white belly. Often found in suburban areas. Crashes into foliage to snatch insect prey. Has distinctive "mee-choo" call.
Orange-breasted Bunting
Passerina leclancherii
Beautiful small bunting of lowlands and foothills; endemic to west Mexico. Occurs in brushy woodland and edge, adjacent weedy fields, and open grassy areas. Often in small groups, feeding on roadside grasses and flushing up with brilliant blue flashes. Also feeds at all levels in fruiting trees and bushes. Male unmistakable: electric turquoise blue and green above; rich yellow below with a burnished orange breast. Female duller overall: greenish above and yellow below, with a bluish tail. Female brighter yellowish below than slightly larger female Painted Bunting.
