Caatinga Cacholote
Pseudoseisura cristata
Unmistakable. Large ovenbird with uniform cinnamon plumage, bushy crest, and yellow eyes. Occurs in dry forests (caatinga) and scrub, often near human habitations. Mostly forages on the ground. Builds a large thorny stick nest. Sings in a duet: the male emits an accelerating series which finishes in a rattle, and the female gives continuous buzzy “zjeep” notes.
识别特征
The Caatinga cacholote is 25 to 26 cm (9.8 to 10 in) long. It is a large, crested, furnariid with a long bill. The sexes have the same plumage. Adults are mostly bright reddish-rufous that is somewhat paler on their underparts. Their flight feathers have fuscous tips and the ends of the tail feathers lack barbs. Their iris is yellow. Juveniles have a shorter crest than adults, with some dusky streaks or bars on the face and underparts and a bluish gray iris.
分类信息
The Caatinga cacholote is monotypic. However, what is now the grey-crested cacholote (P. unirufa) was previously considered a subspecies of it. The two-subspecies P. cristata was then called the rufous cacholote. The two taxa were split following the data in a paper published in 2000. Confusingly, and contrary to the suggestion of the 2000 paper's authors, the South American Classification Committee of the American Ornithological Society and the Clements taxonomy call P. unirufa the rufous cacholote.

分布与栖息地
The Caatinga cacholote is found in eastern Brazil in an area bounded roughly by eastern Maranhão, Paraíba, and central Minas Gerais. It inhabits the woodlands and scrub of the Caatinga biome and also tropical deciduous forest. Away from areas of dense human population it is common around dwellings. In elevation it ranges from 50 to 500 m (160 to 1,600 ft).

行为
The Caatinga cacholote is a year-round resident throughout its range.<p>The Caatinga cacholote feeds on arthropods and plant material. It usually forages in pairs and usually on the ground, where it probes and digs for its prey.<p>The Caatinga cacholote's breeding season has not been defined. Though the species is believed to be mostly monogamous, several observations of breeding pairs included up to four apparent adults, all of whom provisioned nestlings. It is not known if the helpers are related or not to the primary pair. Its nest is a mass of thorny sticks that is typically twice as long as it is wide, placed in a tree fork or on a utility pole. An entrance tunnel near its top leads to an inner chamber lined with pieces of bark and snake skin. One nest in Ceará incorporated a large number of anthropogenic materials including razor blades, a fork, plastic items and fragments, paper, and barbed wire. The clutch size, incubation period, time to fledging, and further details of parental care are not known.<p>The Caatinga cacholote typically sings in duet. One bird, thought to be the male, "gives a long series of well-spaced, very loud, piercing 'tjew' notes". The presumed female replies with "a series of 15–35 well-spaced buzzy 'zjeep' notes". The species' call is "a single 'chuk' ".

White-tailed Trogon
Trogon chionurus
This yellow-bellied trogon is fairly common from Panama to western Ecuador. Males have a dark head and breast with deep indigo iridescence, an iridescent turquoise or purplish back, and a plain white undertail. Females are grayer on the head and breast with a barred undertail that has large white tips on the tail feathers. Note the pale blue eyering. Compare with Gartered Trogon, which has a yellow eyering and different undertail pattern (barred with white tips on males, more black on females). Found singly or in pairs in forests, edges, and gardens up to around 1,000 m. Listen for accelerating series of “pow” notes and purring calls.
Puff-throated Bulbul
Alophoixus pallidus
A large crested bulbul of tropical forests, usually found in the canopy foraging on berries. Body is a light yellow-green, while the wings, tail, and crown are brown. “Puff” of the white throat is slight and not an obvious feature. In the northwestern part of its range, it overlaps with the similar White-throated Bulbul, which has a more scraggly crest, more extensive white on the throat and face, and olive-green wings. Chatters with explosively harsh and barking quality; groups can be very loud and cacophonous.
Yellow-collared Chlorophonia
Chlorophonia flavirostris
This brightly colored bird is found in a limited stretch of the humid foothills and subtropical zone in western Colombia and Ecuador. The male is mostly lime green with a bright yellow belly and collar wrapping around the back of the neck. Note the salmon-colored bill and legs, pale eye, and chestnut markings on the sides of the neck. Females are duller and less sharply dressed than males, but still mostly green with a yellow belly. Can be found in pairs or flocks, usually high in the canopy, where they blend in with the foliage. Often seen around fruiting trees or clumps of mistletoe. This species undergoes erratic seasonal movements, so it can be common in an area but then disappear for months. Listen for the plaintive, high-pitched “teew” calls.
