Rufous-bellied Chachalaca
Ortalis wagleri
Noisy, long-tailed game bird of tropical forest and edge, usually found in small groups. Endemic to west Mexico. Most often detected by its raucous song, which carries well. Feeds on ground and also high in trees, where runs along branches; eats fruit. For a big bird, can be surprisingly hard to see (wary in areas where hunted), and slips away from view quite easily. The dark rusty belly and tail tips are diagnostic. Inland from Puerto Vallarta, may hybridize with West Mexican Chachalaca.

Olivaceous Greenlet
Hylophilus olivaceus
A small, vociferous vireo of east Andean cloud forest. Yellow underparts and crown, pale eye, and pinkish bill help separate it from other species in range. Usually stays high in the trees and sometimes follows mixed-species flocks. Sings frequently, belting out a squeaky and sometimes monotonous series of notes such as “twee-twee-twee…” or “soowe-soowe-soowe …”
Lesser Ground-Cuckoo
Morococcyx erythropygus
Furtive and rarely seen, but loud song carries well and sounds like a referee’s whistle being blown faster and then slower. Inhabits brushy dry woodland in tropical lowlands, where most of the time it walks stealthily on the ground. When alarmed it usually freezes offering good views—if you are lucky. Note the boldly colored turquoise and yellow skin around the eye and the warm buffy or cinnamon-colored underparts.
Speckled Spinetail
Thripophaga gutturata
Fairly small, long-tailed reddish-and-tan bird. Light brown body, with reddish tail, wings, and crown, and prominent fine black spotting in the face and breast. Usually forages singly or in pairs in the midstory of mature or secondary rainforest, often with mixed-species flocks. Tail appears very reddish, even from below; smaller than similar foliage-gleaners, which are often present in the same flocks. Its song is an often overlooked, even-paced series of very high notes.
