Birdfinding.info ⇒  Locally common in several parts of its large range.  On Jamaica consistent sites include Rocklands Bird Sanctuary, Windsor, Stewart Town, Marshall’s Pen, Hardwar Gap, and Green Castle Estate in Robin’s Bay.  In the D.R., it can be found west of Barahona on Santa Elena Road and along the lower part of Alcoa Road.  In Mexico, consistent sites include San Blas (Nayarit), El Cielo Biosphere Reserve (Tamaulipas), Palenque (Chiapas), and Xocén Reserve (Yucatán).  Central American sites where it is often found include: Tikal National Park in Guatemala; the Negroman area in Belize; Cuero y Salado Wildlife Refuge and Blue Harbour Tropical Arboretum (on Roatán Island) in Honduras; and Isla Juan Venado and Montibelli Reserves in Nicaragua.

Northern Potoo

Nyctibius jamaicensis

Tropical lowlands of Middle America and the West Indies.

Inhabits various wooded and semiopen habitats, including tropical forests, mangroves, savannas, agricultural land, and settled areas.  Typically feeds at woodland edge or in forest canopy.

In Middle America, occurs in lowlands and foothills of both slopes from Mexico (Sinaloa and Nuevo León) south to northern Costa Rica, including all of the Yucatán Peninsula, Cozumel, and the Honduran Bay Islands (Utila, Roatán, and Guanaja).

In the West Indies, resident on Cuba, Jamaica, Hispaniola and Gonâve Island.  Its presence on Cuba was confirmed only in the 1990s, and the extent of its distribution there is not fully understood, but it has been recorded from several areas in both the west and the east.  On Jamaica, it is widespread in diverse habitats, including forests, towns, hotel grounds, golf courses, and open agricultural land, where it uses fenceposts and utility poles as hunting perches.  On Hispaniola, it is known mainly from the foothills of the Sierra de Bahoruco and the east-central Dominican Republic, but probably occurs more widely in areas that are not well surveyed.

There are records of vagrants from the smaller islands Desecheo and Mona, west and east of Hispaniola, which indicates a propensity for dispersal over water and helps explain its presence on so many islands.

Identification

A large potoo that varies widely in color and pattern.  Some are mostly gray mixed with black and white; others have variable amounts of brown and rusty highlights.

The upperparts are especially variable.  In general, they are heavily mottled for camouflage and have narrow but distinct black latitudinal streaks, especially on the head and back.  Most individuals show dark “braces” or rows of blackish blotches on the sides of the back, and a warmer shade of brown on the wing coverts.

The underparts are less variable than the upperparts, usually pale gray overall and finely mottled with thin black streaks.  Most have a necklace or bib of black blotches on the upper chest, often distributed irregularly.

Voice.  Typical call is a drawn-out, guttural croak, BAAAAAAAAAH, usually followed by a brief series of one to four quicker, inflected grunts or yips:

The long croak is highly consistent across numerous individuals recorded in many parts of its range.  In contrast, the grunts or yips vary widely in number, length, tone, inflection, etc., but these differences do not appear correlated with particular populations.  Just within Jamaica, for example, the available recordings of these sounds vary widely.

Also gives sharp, raspy alarm calls.

Cf. Common Potoo.  Northern and Common Potoos occur near one another in Nicaragua and Costa Rica.  They are essentially identical by sight but vocally distinct.  Northern’s primary call is a long guttural croak, whereas Common’s is a smooth, mournful series of descending whistles.

Cf. Great Potoo.  Northern and Great Potoos overlap from Chiapas to Costa Rica and resemble one another both visually and vocally.  Both have guttural calls, but Northern typically gives a long, even-toned croak that is usually followed by much shorter bursts, whereas Great barks repeatedly and its voice is smoother and more resonant.

Visually, Great is larger and proportionately larger-headed, but both are large and large-headed, so this difference is not always obvious.  The key difference is in the upperparts, where Northern is mottled and streaked, whereas Great is typically pale and finely vermiculated.  Young Northern Potoos are also very pale—but usually more ghostly whitish than Great Potoo, with contrasting black streaks.

Notes

Polytypic species consisting of five recognized subspecies: lambi (western Mexico), mexicanus (eastern Mexico to Nicaragua), costaricensis (Nicaragua and Costa Rica), jamaicensis (Jamaica), and abbotti (Hispaniola and Gonâve).  The newly discovered Cuban populations have not been ascribed to any of the recognized subspecies.

The mainland and West Indian subspecies seem inherently likely to be distinct forms or multiple species based on their geographical separation, but they lack clear, consistent differences in voice or appearance.  On most characteristics, variability within subspecies appears to swamp any variability among them—so apart from location, there does not appear to be any characteristic that enables identification of a Northern Potoo at the subspecies level.
