Malagasy Palm Swift

Cypsiurus gracilis

A very slender gray-brown swift with a long, deeply forked tail that is often held closed, making it look needle-like and pointed. The erratic flight pattern, with frequent direction changes and rapid wingbeats on long, scythe-shaped wings, is distinctive. Less gregarious than other swifts; usually found in pairs or small flocks, and association with other swallows and swifts is usually only fleeting. Forages over a wide variety of habitats with palms, including savanna, coastal scrub, towns, villages, cultivated areas, forest edge, and clearings, from sea level up to 1100 meters of elevation, preferring lowlands. Nests and roosts in palms, especially Hyphaene, Bismarckia, and coconut palms. Gives a high-pitched, metallic “tre-tit-tit-tit-tit-tit-tit-tit” call, solitarily or in unison with others. Separated from other swifts by its longer and thinner tail. Further separated from the larger Madagascar Swift by its much weaker and more fluttering flight.

Olive-naped Weaver

Olive-naped Weaver

Ploceus brachypterus

A medium-sized, pale-eyed weaver in which males and females are distinctly different, but both are colorful. Note olive-green back and nape and slender black mask through the eye. Male has a black throat and cinnamon-brown blush around the face. Found in woodland, thick scrub, moist savanna, gallery forest, and forest clearings and edge. Usually alone or in pairs. Vocalizations are typical of weavers: “chet” notes and a sizzling, “radio static” song. Formerly treated as the same species as Black-naped Weaver, under the name “Black-necked Weaver.”

Eastern Paradise-Whydah

Eastern Paradise-Whydah

Vidua paradisaea

The breeding male is buff, chestnut, and black with a 21-centimeter tail that is laterally flattened with both short bulging feathers and long, tapering dagger-like feathers. The female and non-breeding male have a strongly contrasting black-and-white head, including a characteristic dark bill and a double “C” pattern under the ear. The males aggressively hold territories, but small groups forage together in dry and moist savanna. After breeding, they flock with other seedeaters. This whydah gives dry chip calls and imitates the calls of the Green-winged Pytilia, which it parasitizes. The Broad-tailed Paradise-Whydah differs from the Eastern Paradise-Whydah as follows: the breeding male has a shorter broader tail; the non-breeding male and female have a paler bill and a plainer facial pattern.

Olive Honeyeater

Olive Honeyeater

Lichmera argentauris

A nondescript sparrow-sized songbird with a slender, downcurved bill. Entirely olive-green above and uniform pale gray below, but note head pattern, which includes a prominent whitish smudge on the cheeks and dull bare skin below the eye. Juvenile has a pink facial patch. Singles, pairs, or groups inhabit scrubland, wooded areas, and coconut plantations in lowlands. Confined to islets in the Moluccas and to West Papua, where it is readily identified by its head pattern. Harsh, squeaky vocalizations include “tchew” and “grrt” notes and “chi-witchoo” or “witch-oo” phrases.
