The wing-banded wren (Microcerculus bambla) is a species of bird in the family Troglodytidae. It is found in Brazil, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. [2]
The wing-banded wren was described by the French polymath Georges-Louis Leclerc, Comte de Buffon in 1779 in his Histoire Naturelle des Oiseaux from a specimen collected in Cayenne, French Guiana. [3] The bird was also illustrated in a hand-colored plate engraved by François-Nicolas Martinet in the Planches Enluminées D'Histoire Naturelle that was produced under the supervision of Edme-Louis Daubenton to accompany Buffon's text. [4] Neither the plate caption nor Buffon's description included a scientific name but in 1783 the Dutch naturalist Pieter Boddaert coined the binomial name Formicarius bambla in his catalogue of the Planches Enluminées. [5] The wing-banded wren is now one of four species in genus Microcerculus that was introduced by the English naturalist Osbert Salvin in 1861. [6] [2] The genus name is from the Ancient Greek mikros meaning "small" and kerkos meaning "tail". The specific epithet bambla is a homophone from the French bande blanche meaning "white band". [7]
Three subspecies are recognized: [2]
A holotype of Wing-banded Wren Cyphorinus albigularis Sclater (Proc. Zool. Soc. London. pt. 23, 1855, p. 76, pl. 88). An adult male is held in the vertebrate zoology collection of National Museums Liverpool at World Museum, with accession number NML-VZ D4925. The specimen was collected in Panama by A. de Lattre. The specimen came to the Liverpool national collection via the 13th Earl of Derby collection which was bequeathed to the people of Liverpool in 1851. [8]
The wing-banded wren is 11.5 cm (4.5 in) long and weighs 17 to 19 g (0.60 to 0.67 oz). Adults of the nominate subspecies have a blackish-brown crown, upperparts, and tail. The upperparts have obscure dusky markings and the tail has obscure darker brown bars. Its dark chocolate-brown wing shows a broad white band when closed. It face is dark brown, the chin and throat gray, the chest gray-brown with dark tips on the feathers, and the belly and flanks a purer brown than the chest. The belly and flanks have faint bars. The juvenile's underparts appear scaly and it does not have the white wingbar. The upperparts of M. b. caurensis are a brighter rufous than the nominate's and it does not have the dusky markings on the back and breast. M. b. bambla is similar to caurensis but has a paler throat. [9]
The subspecies of wing-banded wren are found thus: [2] [9]
The wing-banded wren inhabits lowland rainforest, both those with a dense understory and more open ones. It appears to require a wet understory with many rotting logs. In Venezuela it mostly ranges from sea level to 1,100 m (3,600 ft) but can be found as high as 1,500 m (4,900 ft). [9]
The wing-banded wren forages on and very near the ground, preferring to explore rotten logs and other woody detritus. Unlike other members of its genus, it seems to only rarely forage in leaf litter. Its diet is mostly arthropods but it has also been seen carrying tiny frogs to a nest. [9]
Two wing-banded wren nests have been described. Both were found in late March in French Guiana and each held a well-grown nestling being fed by both parents. Both nests were about 2 m (6.6 ft) above ground in a cavity in an arboreal termite nest. The cavities were probably excavated by a yellow-billed jacamar (Galbula albirostris). [9]
The wing-banded wren's song is "a beautiful series of 3–6 clear, pure high-pitched notes separated by short pauses", sometimes extended by a "long, sustained glissando". Its call note is "a sharp metallic 'click'". [9]
The IUCN has assessed the wing-banded wren as being of Least Concern. [1] Though it does not appear to be common anywhere, it "appears to be at relatively little risk at present, as large parts of its range are very sparsely populated by human beings." [9]
The red-billed blue magpie is a species of bird in the crow family, Corvidae. It is about the same size as the Eurasian magpie, but has a much longer tail, one of the longest of any corvid. It is 65–68 cm (25.5–27 in) long and weighs 196–232 g (6.9–8.2 oz).
The white-naped woodpecker is woodpecker which is a widespread but a scarce breeder in the Indian Subcontinent. It is associated with open forest and scrub with some trees. It nests in a tree hole, laying one or two white eggs.
The diederik cuckoo, formerly dideric cuckoo or didric cuckoo is a member of the cuckoo order of birds, the Cuculiformes, which also includes the roadrunners and the anis.
The tufted coquette is a tiny hummingbird that breeds in eastern Venezuela, Trinidad, Guiana, and northern Brazil. It is an uncommon but widespread species, and appears to be a local or seasonal migrant, although its movements are not well understood.
The white-winged swallow is a resident breeding swallow in tropical South America from Colombia, Venezuela, Trinidad, and Argentina. It is not found west of the Andes. This swallow is largely non-migratory.
The pied water tyrant is a small passerine bird in the tyrant flycatcher family. It breeds in tropical South America from Panama and Trinidad south to Bolivia.
The southern white-fringed antwren is an insectivorous bird in the antbird family Thamnophilidae. It is a resident breeder in tropical South America from Colombia southeast to the Guianas and Brazil.
The greater striped swallow is a large swallow that is native to Africa south of the equator.
The buff-necked ibis, also known as the white-throated ibis, is a fairly large ibis found widely in open habitats of eastern and northern South America. It formerly included the similar black-faced ibis as a subspecies, but that species is almost entirely restricted to colder parts of South America, has a buff lower chest, and lacks the contrasting large white wing-patches.
The giant snipe is a stocky wader. It breeds in South America. The nominate subspecies G. u. undulata occurs in two distinct areas, one in Colombia, and the other from Venezuela through Guyana, Suriname and French Guiana to extreme north-eastern Brazil. The southern subspecies G. u. gigantea is found in eastern Bolivia, eastern Paraguay and south-east Brazil, and probably also in Uruguay and north-eastern Argentina.
The grey-breasted sabrewing is a species of hummingbird in the family Trochilidae.

The fulvous shrike-tanager is a South American bird in the tanager family Thraupidae. It is found in Brazil, Colombia, Ecuador, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitat is subtropical or tropical moist lowland forests.
The helmeted pygmy tyrant is a species of bird in the family Tyrannidae. It is found in Brazil, Colombia, French Guiana, Guyana, Peru, Suriname, and Venezuela. Its natural habitats are subtropical or tropical moist lowland forests and heavily degraded former forest.
