Hispaniolan Nightjar
Antrostomus ekmani
Dark brown and buff nocturnal bird often first noted by its distinctive song, a low, burry “pit, whoo-vore?”, often given in rapid succession. Similar to migratory Chuck-will’s-widow, but plumage is darker and less buffy, and tail is tipped white in male or buff in female, though this may only be evident when seen from below. When seen from above, pale tail tip is indistinct, and helps separate it from the smaller Least Pauraque, which has a narrow and well-defined band at the end of the tail. Short wings that do not reach tail tip help distinguish it from Antillean Nighthawk. Inhabits forest and edge, and often seen along roads at night as its eyes gleam in the headlights of passing cars or the spotlights of birders. Sallies out to catch insects from the ground or a branch. Sleeps by day on the ground or a low perch. Endemic to Hispaniola. Cuban birds are now considered a separate species, Cuban Nightjar.
Identification
The Hispaniolan nightjar is 26 to 30 cm (10 to 12 in) long. The upperparts are dark brown speckled with grayish buff, pale buff, and grayish brown, and the crown has broad black streaks. The tail is brown and the three outer pairs of feathers are broadly tipped with white (male) or buff (female). The innermost pair has grayish brown chevrons. The wings are brown with spots, bars, and mottling of lighter shades. The face is tawny with dark brown speckles, the chin and throat dark brown with cinnamon speckles, the breast dark brown with large spots and smaller speckles of buffy white, and the belly and flanks dark brown with gray speckles. The Cuban nightjar subspecies endemic to Isla de la Juventud (A. cubensis insulaepinorum) is smaller, much darker, and has a shorter tail than the Hispaniolan nightjar.
Taxonomy
The Hispaniolan nightjar was originally described as Antrostomus ekmani; the genus was later lumped into genus Caprimulgus and still later restored as a separate genus. The International Ornithological Committee (IOC), BirdLife International's Handbook of the Birds of the World (HBW), and the Clements taxonomy consider it a monotypic species. The American Ornithological Society (AOS) considers it and the two subspecies of the Cuban nightjar (A. cubanensis) to be subspecies of the Greater Antillean nightjar.The species is named for Swedish naturalist Erik Leonard Ekman, who first described the species in the 19th century.

Range and habitat
The Hispaniolan nightjar is found only on the large island of Hispaniola. It is much more common in the western third of the Dominican Republic than the eastern part of that country, and is very rare in Haiti to the west of the Dominican Republic. It mostly inhabits broadleaf forests at middle elevations and shuns low elevation thorn scrub and higher elevation pine forest. In elevation it ranges up to about 1,825 m (5,990 ft).

Behavior
The Hispaniolan nightjar is crepuscular and nocturnal. Its prey is insects that it captures in flight, though whether that is during continuous flight or by sallies from a perch or the ground is not known.<p>The Hispaniolan nightjar breeds between April and July. The usual clutch of two eggs is laid directly on the ground without a nest. Both sexes are believed to incubate the eggs.<p>The Hispaniolan nightjar's song is "a rather harsh, buzzy call of one syllable" that starts with a click and rises in pitch. Its apparent disturbance call is "low-pitched, brief calls, paraphrased as quat…quat…quat…".

Other Birds
Rufous-crowned Eremomela
Eremomela badiceps
A small warbler-like bird usually seen in small groups or flocks foraging high above the ground in the forest or forest edge. Pale below with a distinct black chest band separating the white throat from the light gray belly, giving these eremomelas a distinctive “belted” appearance. Upperparts are uniformly gray except for a reddish cap and dark face. Overlaps locally with Turner’s Eremomela in the eastern part of its range, but note Rufous-crowned Eremomela’s extensive reddish cap and big, broad black chest band. Calls consist of a buzzy, sometimes multi-parted “brzrt,” as well as higher-pitched twittering calls sometimes interspersed with more whistled notes and trills.
Peregrine Falcon
Falco peregrinus
Sleek, fast-flying large falcon. Always look for a grayish back in adults, long wings that almost reach the tail tip, and powerful but slender build. Dark mark below each eye varies in shape and size. Juveniles are more heavily patterned below than adults, and can be quite brownish above. Patterning varies considerably across a wide global range, with back color ranging from pale gray in Central Asian “Red-capped” to slaty-blue across much of northern Eurasia North America, to almost black in Asian “Shaheen.” Chases prey down at high speeds with continuous powerful wingbeats. Becoming increasingly common in parts of range, especially in cities, where they can nest on tall buildings and feed on pigeons. Adaptable, and can be seen in a wide range of habitats; often encountered in areas with steep cliffs, as well as around coastal mudflats and open areas with shorebirds.
Rock Sandpiper
Calidris ptilocnemis
Plump, rock-loving shorebird with slightly droopy bill. Most often seen in nonbreeding plumage, which is fairly dark gray with heavily spotted underparts. Color of legs and base of bill varies from dull greenish to orangey. Breeding plumage shows reddish back and smudgy black belly. Juveniles show some rusty tones and have neat white fringes on wing feathers. Some variation across range; breeding population on Pribilof Islands in Alaska is larger and paler. Breeds on tundra; winters on rocky coastlines, sometimes feeding on mudflats. Typically in flocks in winter, often mixed with turnstones or Surfbird. Extremely similar to Purple Sandpiper but no range overlap.
