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.

行为
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".

Lafresnaya lafresnayi
This unique hummingbird is best recognized by its long decurved bill and mostly white tail (especially visible in flight). Males are mostly green with a black belly. Females are whitish or buffy below with dense green speckling. Found in high elevation forests and edges from Venezuela to Peru. Occurs from around 2,500m to 3,400m, occasionally wandering lower.

Long-legged Buzzard
Buteo rufinus
A large, long-winged buzzard which may recall a small eagle in size. Variable plumage with three color morphs. All have obvious dark carpal patches at the wrist of the wing. Juveniles lack the adult’s prominent black trailing edge to the wings. Often hunts from a prominent perch, or sits on the ground and scans for prey. A species of open steppe and desert country, sometimes in more wooded areas but always near big open spaces. Compare with similar Common and Upland Buzzards, as well as Rough-legged Hawk; note long-winged structure, size, and wings held in “V” in soaring flight.
