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.
Identification
The lesser ground cuckoo is 25 to 28 cm (9.8 to 11 in) long. Males weigh about 58 to 66 g (2.0 to 2.3 oz) and females about 56 to 76 g (2.0 to 2.7 oz). Females are somewhat paler than males but otherwise do not differ. They have a slightly decurved bill with a blackish brown maxilla and an orange mandible. Their face is intricately patterned, with a bright yellow ring around the eye with bare blue skin behind it and thin black lines surrounding the area, a short indistinct whitish stripe above the eye, and cinnamon ocracous cheeks. Adults of the nominate subspecies have a grayish brown crown, an olive brown nape and back, a sooty blackish lower back and rump, and olive brown uppertail coverts. Their tail is mostly olive brown with a purplish bronze gloss and buff to whitish tips on top and light grayish brown on the underside with dull blackish bands near the end of the outer feathers. Their underparts from chin to vent are cinnamon ochraceous. Immatures are similar to adults but duller and do not have the pale tips and blackish bands on the tail.<p>Adults of subspecies M. e. mexicanus are larger and paler than the nominate, with somewhat grayer upperparts and underparts tending to ochraceous buff or pale buff, but a darker underside to the tail.

Range and habitat
The nominate subspecies of lesser ground cuckoo is found from southern Mexico south through Guatemala, El Salvador, Honduras, and Nicaragua into Costa Rica. M. e. mexicanus is found on the Pacific slope of western Mexico between Sinaloa and the Isthmus of Tehuantepec. The species inhabits semiarid to arid landscapes including the interior and edges of woodlands, thorn forest, secondary forest, and savanna. Those in southwestern Mexico are almost exclusively found in thorn forest.

Bald Parrot
Pyrilia aurantiocephala
A most remarkable parrot with an entirely bare orange head and nape. Note the bright orange shoulder patch and in flight the red underwings. Occurs in humid forests, including those on white-sand forests. In flight gives nasal, high-pitched “skee-skee-skee” notes.
Spot-backed Antwren
Herpsilochmus dorsimaculatus
Small canopy antwren with a long, graduated tail. Males are largely gray with a black crown and a bold white eyebrow; the black spots on the back can be difficult to see. Females have a buff forehead and breast sides, with the black crown spotted white. Inhabits humid lowland forest and seasonally flooded forest in some regions. Almost invariably seen accompanying canopy mixed-species flocks. The song is a somewhat deep trill that slightly ascends and then descends: “wiwiwurrrrr.”
Reunion White-eye
Zosterops olivaceus
An unusual white-eye with dark plumage and a long, curved bill. Olive-green above and gray below with a broad white eye-ring. Found on the island of Reunion in humid forest, mostly at middle and high elevations. Vaguely similar to Reunion Gray White-eye, but easily separated by the white eye-ring and the olive-green back. Gives a warbling song and a variety of calls including a short, accelerating series of chipping notes.
