Information AboutWhite-flanked Antwren |
The White-flanked Antwren, ''Myrmotherula axillaris'', is a Passerine Bird in the Antbird family. It is a resident breeder in tropical Central and South America from El Salvador and Honduras south to Bolivia and southern Brazil , and on Trinidad . This is a common and confiding bird of primary and second growth forest, usually found in small groups. The female lays two purple-marked white eggs, which are incubated by both sexes for 16 days to hatching, in a small plant fibre and dead leaf cup nest low in a tree or shrub. The White-flanked Antwren is typically 10.7 cm long, and weighs 8.1 g. The adult male has dark grey upperparts, black underparts, and black wings with bars of white spots. The flanks and underwings are white. The female and immature male have brown upperparts, yellowish-buff underparts and weakly barred rufous wings. Her flanks and underwings are white, much like the male. Males of the distinctive western race ''M. a. melaena'' have black upperparts and underparts, and the female is darker than nominate ''M. a. axillaris''. The White-flanked Antwren feeds on small Insect s and other Arthropod s taken from twigs and foliage in the lower branches of trees. It has a ''queep'' whistle followed by a trilled ''trrrrrr''. ''M. a. melaena'' has a two note call, ''naa-who'' and a whistled descending ''pee pee pee-pee-pee-pee-pee-puu-puu'' call. Given the differences in plumage and vocalisations, the two forms may possibly be different species. References
