Red-breasted Chat
Granatellus venustus
Easily overlooked, warblerlike bird of tropical forest in lowlands and foothills of west Mexico and extreme western Guatemala. Hops around, mainly at low levels in tangled understory, often fanning and waving around its rather long, white-edged tail. Male is striking, with red breast and bold black-and-white head pattern. Female-plumaged birds are seen more often and can be puzzling, but note buffy face and breast with a dark beady eye, mostly grayish upperparts, and white-edged tail.
Identification
The red-breasted chat is 14.5 to 16 cm (5.7 to 6.3 in) long; 12 specimens weighed between 10.2 and 11.4 g (0.36 and 0.40 oz). The adult nominate male's upperside is mostly bluish gray. Most of the face is black, though it has a broad white supercilium, and there is a black band across the chest. The chin, throat, sides, and flanks are white; the chest, lower breast, belly, and vent area are vermilion. The adult female's upperparts are slate gray. Most of its face is shades of buff and gray. Its breast and belly are buff and the vent area salmon pink.<p>The immature male's head and upperparts are similar to those of the adult but with less black. The throat and underparts are whitish with a pink wash to the rear. The immature female is similar to the adult.
Taxonomy
The genus Granatellus was traditionally placed in family Parulidae, the New World warblers. Studies of DNA sequences in the early 2000s resulted in its being moved to its present family. The red-breasted chat and the other two members of its genus, gray-throated chat (G. sallaei) and rose-breasted chat (G. pelzelni) form a superspecies.<p>The red-breasted chat has two subspecies, the nominate Granatellus venustus venustus and G. v. francescae.

Range and habitat
The nominate red-breasted chat is endemic to western Mexico. It is found year-round from Sinaloa south to the Isthmus of Tehuantepec and from there into interior Chiapas and possible into northern Guatemala, though there are no records there. It also occurs inland to Morelos along the Balsas River. G. v. francescae is restricted to Islas Marías off Nayarit. It primarily inhabits thorn forest and scrubby woodland and can be found in the understory of secondary forest and other heavy growth. In addition, the species has been reported in evergreen swamp forest inland of mangrove swamps and along rivers. In elevation it generally ranges from sea level to 1,200 m (3,900 ft) though locally it occurs as high as 1,600 m (5,200 ft).

Behavior
Little is known about the red-breasted chat's foraging habits or diet. It is assumed to eat insects and other arthropods.<p>The red-breasted chat breeds in the wet season, from May to September. Its nest is a cup made of Spanish moss and other fibers lined with finer material. The clutch size is two to four. Females alone incubated the nests but both sexes provided food to nestlings.<p>The red-breasted chat's song is a repeated "variable, fairly sweet warble" [1]. Its call is a repeated "wet plek or plik" [2].

Cape Grassbird
Sphenoeacus afer
A chunky, streak-backed warbler with a rusty head and wings, a ragged rufous tail, and black moustache stripes. It avoids woodland and trees, preferring rank areas with long grass, scrubby edge, and wet heathland (fynbos). It hops and clambers through dense brush and thickets, then flies low on rapidly-beating wings in labored flight to the next bush, immediately diving into cover. But it will also perch on prominent tall shrubs, like proteas, and sing its melodious tinkling jumbled song that starts softly and gets progressively louder. It also has a distinctive flat mewing “meeeeep” call. The Moustached Grass-Warbler is similar to the Cape Grassbird, but it has a plain unstreaked back, a broad black tail, and a pale eye.
Black-faced Antbird
Myrmoborus myotherinus
Short-tailed antbird of forest understory. Both sexes have black face. Males are gray with white wingbars; females are brown above, buffy below, with cream wingbars and a white or buffy throat. Forages singly or in pairs low in the undergrowth of mature forest. Usually inhabits more mature forest than similar White-browed Antbird, but there is some overlap. Note differences in facial pattern; males lack the white eyebrow and females lack the orange eyebrow seen on White-browed Antbirds. Female Black-faced Antbirds also have browner underparts than White-browed. Listen for an even-paced series of 5–7 whistles that is slightly higher in the middle. In the southern part of its range, these whistles are pure-toned; in the north, they are harsher.
Chocolate Boobook
Ninox randi
A medium-sized owl of lowland and foothill forest and edge. Dark brown on the upperparts and head, with white underparts thickly streaked with reddish-brown. Face grayish and eyes yellow. Occurs together with several other boobook species, but Chocolate is much larger, with plain brown wings and more demarcated streaking on the chest. Voice is also different: a series of identical, medium-pitched “boop!” notes.
