Dusky Long-tailed Cuckoo
Cercococcyx mechowi
A dark brownish-gray cuckoo with an unusually long tail and barred underparts. Found in the understory and at middle levels of humid forest at low and middle elevations. Shy and retiring, most easily found by voice. Very similar to Olive Long-tailed Cuckoo and best separated by voice, but also identified by darker upperparts, broader barring on the underparts, and richer rufous on the undertail. There are two main vocalizations: a quick series of three rising whistles, and a long, rapid series of whistles that slows and falls slightly toward the end. In the far western part of the range, the three whistles are slow and each one is progressively higher in pitch; elsewhere, the whistles are fast and identical.
Identification
The dusky long-tailed cuckoo is about 33 cm (13 in) long and weighs 50–61 g (1.8–2.2 oz). The head, nape and upperparts are dark brown, washed sooty-grey and with a purple-blue iridescence. The wings are dark brown, with buff and white spots. The underparts are white, with blackish-brown bars, and the vent is buff. The tail is long and graduated. The eyes are dark brown, the beak is greenish-black and the feet are yellow. The male and female are alike. The juvenile bird has a blackish throat and rufous bars on its upperparts. The nestling's skin is black, and it has a yellow rump and pale feet.
Taxonomy
The species was described by Jean Cabanis in 1882. It is monotypic. The specific epithet mechowi honours Friedrich Wilhelm Alexander von Mechow, a Prussian explorer. The name occidentalis for a population with different songs is a nomen nudum.

Range and habitat
This cuckoo has a discontinuous distribution and is found in Angola, most of Cameroon, the Central African Republic, Republic of the Congo, Democratic Republic of the Congo, Equatorial Guinea, Gabon, Tanzania, and Uganda. Populations west of the Bakossi Mountains, in northwestern Cameroon, Ghana, Guinea, Ivory Coast, Liberia, Nigeria, Sierra Leone, and Togo, are now considered a distinct species, the whistling long-tailed cuckoo (C. lemaireae) due to their differing calls. Its habitat is forests, preferring ones with dense undergrowth and lianas. It also occurs in tall secondary forests and forests along rivers.

Other Birds
Snowy Plover
Anarhynchus nivosus
Small, pale plover with broken collar. In breeding plumage, black ear patch is distinctive. Thin black bill separates from other small plovers at all times of year. Also note relatively long, grayish legs. Typically uncommon. Found on sandy beaches on the coast and inland; usually singly or in small loose flocks. Larger numbers gather at key sites after breeding in summer and fall. Quickly darts around searching for invertebrates in the sand.
Ladder-tailed Nightjar
Hydropsalis climacocerca
Large nightjar of tropical lowlands, often found near waterways. Sandy brown with indistinct light markings and a fairly long tail; in flight, males show large white wedges on outer tail feathers. Roosts during the day in vegetation along the edges of oxbow lakes and rivers and forages around sandbars and river edges at night. Does not call often, but occasionally gives soft chirping calls in flight.
Northern Bobwhite
Colinus virginianus
Small and rotund with intricate brown, black, and white patterning. Some striking variation in plumage across range. Most males, including those in the eastern U.S., have bold black and white head pattern and heavy white spotting on belly. In Mexico, males can be entirely cinnamon-colored below and have a fully black head; some might have a white eyebrow or a dark chest band. Females are more consistent throughout range: look for buffy throat and eyebrow. Pairs or small groups are found in scrubby fields and brushy woods. Usually on the ground, but occasionally perches in trees when singing. The only quail native to the eastern U.S., where populations are declining sharply. Listen for distinctive “bob-WHITE!” whistle.
