The white-flanked ant hatchers ( Myrmotherula axillaris ) belong to the genus Myrmotherula within the ant bird family (Thamnophilidae) .
The species is widespread and occurs in Central and South America from El Salvador and Honduras to the Amazon basin and Bolivia , Ecuador , western Colombia and Peru .
The distribution area includes moist undergrowth in the mountain foothills of the eastern Andes , in the western Amazon basin up to 1800 m altitude.
The Latin additional species refers to the armpit .
Until recently, that was silvery edge Antwren ( Myrmotherula luctuosa ) as conspecific viewed.
features
The species is 9 to 10 cm tall and weighs between 5 and 9 g. It is the only one with strong white flank spots with otherwise dark plumage. Since the bird often flaps its wings nervously, these spots are a striking distinguishing feature. The male is dark gray with a white interscapular spot, wings and tail are blackish, the control feathers have a gray border, the wing-coverts and tail feathers have white tips. The throat, chest and underside are black, the sides are eponymous white. The female is olive-brown on the upper side with a yellow-brown sheen on the trunk, wings and tail are dark brown with light cinnamon-colored edges, the sides of the head are pale-spotted olive-brown, the underside yellow-brown with olive-brown flanks. Young birds look like the females, but the wings are mixed yellow-brown, the underside gray to white.
Geographic variation
The following subspecies are recognized:
- M. a. albigula Lawrence , 1865 - Southeast Honduras to western Colombia and western Ecuador
- M. a. melaena ( PL Sclater , 1857) - Northwest Amazonia
- M. a. heterozyga J. T. Zimmer , 1932 - Eastern Peru and Western Brazil
- M. a. axillary ( Vieillot , 1817), nominate form - Venezuela, Guayana , Trinidad and eastern Amazon basin in Brazil to northeastern Bolivia
- M. a. fresnayana ( d'Orbigny , 1835) - southeastern Peru and northwestern Bolivia
voice
The singing consists of a quick succession of abrupt tones, relatively deep, clearly sloping and louder at the beginning, then slowing down.
Way of life
The food consists mainly of small insects and spiders , which are hunted in pairs, often in mixed hunting communities at a height of 2 to 5 m.
The nest consists of leaves placed on a fork of a branch. The breeding season in Costa Rica is between March and July, in Panama between March and August, in French Guiana between July and December and between February and March, in Ecuador between February and October, in Peru between September and November and in Brazil between June and December.
