Bare-legged Owl
Margarobyas lawrencii
A charming owl with large dark eyes, bushy white or buff eyebrows, and a buffy mustache. At night hunts woodlands or open areas with large trees; during the day roosts in tree cavities or caves. Its song is a distinctive accelerating soft “hoo-hoo-hoo-hoo-hoo…” that has a “bouncing ball” rhythm; occasionally gives a screech. No similar species within its range.
Identification
The bare-legged owl is relatively small, measuring 20–23 cm (8–9 in) long, and weighing about 80 g (2.8 oz). Its name comes from its featherless green-yellow legs, similar to those of the burrowing owl. These owls have dark brown eyes, no ear tufts, a cream-colored facial disk, and brown rictal bristles. The upperparts of these birds are largely brown to slightly rufous in colour. Their wing feathers have white barring, and there are white spots on their shoulder and scapular feathers. The underparts are gray- to yellow-white, with some brown streaking and occasionally even cross-barring on the sides and breast.<p>Juvenile bare-legged owls have similar plumage colors to adults, but have fewer white spots.
Taxonomy
The bare-legged owl was described in 1800 and for a time, it was considered the same species as the Puerto Rican owl. However, it was later determined to be its own species by George Newbold Lawrence in 1868. It has variously been placed in the genera "Noctua", Gymnoglaux, and Gymnasio. The American Ornithological Society moved it to the genus Otus in 1998. However, in 2003, they moved the bird back to the genus Gymnoglaux based on physical and vocal differences between the bare-legged owl and typical screech-owls. Finally, in 2008, the genus Margarobyas was proposed, as it was found that Gymnoglaux was a junior synonym of Gymnasio.<p>There is one possible subspecies: M. l. exsul, found in western Cuba and the Isla de Juventud. It is supposedly differentiated by a darker brown color and more spots, although this subspecies is not generally recognized.<p>Margarobyas comes from the Greek margarites, a pearl, and byas, an owl. This name was given as a reference to Cuba's status as the "Pearl of the Antilles." The species name, lawrencii, is in honor of George Lawrence.

Eurasian Kestrel
Falco tinnunculus
Small falcon with distinctive male plumage: gray head, rusty back, gray tail with broad black tip. Female is brownish above, with barring on the back, wings, and tail. Note rather pointed wingtips (unlike rounded wings of Accipiter hawks), and distinct dark spotting on the breast. Inhabits open and lightly wooded country, farmlands, grasslands, and heathlands; often seen over grassy areas beside roads and at airports. Perches on wires and posts, and typically hunts by hovering, at times fairly high overhead. Very similar to Lesser Kestrel.
Yellow-bellied Sapsucker
Sphyrapicus varius
Striking and unmistakable in most of range; the only sapsucker in eastern North America. Long, solid white wing patch helps distinguish it from Downy and Hairy Woodpeckers. Adult male has red cap and throat; females are similar but with white throat; juveniles are messy brownish-gray overall. The namesake yellow belly can be difficult to see and is sometimes almost absent. Often looks disheveled, especially in fall and winter. Compare with the extremely similar Red-naped Sapsucker, which barely overlaps in range. Note male Yellow-bellied has complete black border around red throat patch, and the white markings on the back are more extensive and messy. Occurs in almost any wooded habitat, breeding in the boreal forest across Canada and wintering as far south as Costa Rica. Like other sapsuckers, drills rows of sap wells into tree bark. Listen for irregular drumming (like morse code) and various nasal calls.
Chestnut Wood-Quail
Odontophorus hyperythrus
This chickenlike bird is bright rufous on the face and underparts and brown above. Female similar to male but rufous more restricted to the upper breast with contrasting gray belly. Also note slight crest, stout bill, and some bare gray skin around the eye. Uncommon in cloud forest of western Colombia. Shy and difficult to see; stays in small groups on the forest floor and rarely comes out in the open. Listen for rollicking whistled song, similar to other wood-quail.
