Ocellated Thrasher
Toxostoma ocellatum
Handsome and uncommon thrasher of oak scrub, thickets, and brushy woodland; endemic to interior highlands of central Mexico. Tosses leaves noisily on the ground, but is usually skulking and rarely seen unless singing. Sings year-round and at any time of day (but mainly early and late), often from a prominent perch. Note the long arched bill, pale eyebrow, brownish eyes, and bold black breast spots (like eyespots, hence the name ocellated). Curve-billed Thrasher occurs in the same areas and is more common, but has golden eyes and weak blurry spotting on breast; beware, song can be similar.
Identification
The ocellated thrasher is 26.5 to 29.5 cm (10.4 to 11.6 in) long; 14 specimens weighed 77.3 to 95.8 g (2.73 to 3.38 oz). Adults' upperparts are dark brown and have a slight olive wash. They have a dull white to buff supercilium and brown cheeks. The folded wings show two white bars and the outer tail feathers have narrow white tips. The underparts are whitish darkening to buff on the belly and brown on the flanks. The breast, sides, and flanks have bold black spots.
Taxonomy
The ocellated thrasher has two subspecies, the nominate T. o. ocellatum and T. o. villai.

Range and habitat
The nominate subspecies of ocellated thrasher is found in central Mexico from San Luis Potosí south to the states of Hidalgo and México. T. o. villai is found in southern Mexico between Puebla and Oaxaca.<p>The ocellated thrasher inhabits a variety of landscapes including arid and semi-arid scrub and the brushy understory of oak and pine-oak forests. In elevation it ranges from 1,400 to 3,000 m (4,600 to 9,800 ft).

Behavior
The ocellated thrasher forages mostly in dense vegetation, on the ground or near it. Though its diet has not been documented, it is presumed to be mostly arthropods, other invertebrates, and possibly fruit.<p>Very little is known about the ocellated thrasher's breeding phenology. Its nest is a cup made of twigs and grass sited in a bush or tree. The clutch size is believed to be two.<p>The ocellated thrasher's song is "a varied, rich warbling in which phrases are repeated two or three times", often sung from atop a bush or tree. Its calls include "a hard, slightly smacking to gruff chehk or tchehk".

Rufescent Prinia
Prinia rufescens
Small prinia with gray head, warm brown upperparts, and white underparts. Also shows white eyebrow and graduated tail with pale tips to the outer tail feathers. Note warmer brown tones and lack of strongly “vested” appearance when compared with Gray-breasted Prinia. Favors brushy or grassy edges as well as more open areas, including agricultural fields and gardens. Forages low in the vegetation, sometimes in mixed-species groups. Song is a loud, resonating “chewchewchewchewchew.”

Black-breasted Weaver
Ploceus benghalensis
Male distinctive in breeding plumage, with extensive yellow forehead and black face, nape, and upper breast. Dark brown above with blackish streaks and dirty white below. Often the black on breast can be replaced with a pale throat, forming a black necklace, partial or complete, of variable width. Non-breeding males often show a much reduced breast band with dark patches on either side. Female and juvenile are brown and white, like females of other weavers, with a buffy eyebrow above a thin, dark eye-stripe. Nests communally. Breeding song is a series of low-pitched buzzes, not as loud as Baya Weaver’s. Mostly found close to water, near tall grass and reeds.

Lesser Rhea
Rhea pennata
This flightless South American relative of the ostriches stands about 5 feet tall with a body about the size of a sheep; no similar species in its range. Rheas roam widely on open Patagonian steppe and also occur locally in open habitats of the Andes, mainly at very high elevations. Can be confiding where used to people, but in other areas wary, running strongly and quickly. Rheas occur singly or in groups, and males take care of the young. Adults have bold pale spots on the body, first-year birds are plainer overall.
