The Western Tropfenameisenwürger ( Thamnophilus atrinucha ), Syn. Thamnophilus punctatus atrinucha , one within the family of Antbirds (Thamnophilidae) to the genus of Thamnophilus .
The species occurs in Central America from Belize and Eastern Guatemala , Costa Rica , Panama to Ecuador , Colombia , Peru and Venezuela .
The distribution area includes moist tropical primary and secondary forest , and forest edges up to 1500 m height.
The Latin additional species comes from the Latin ater 'black' and the Latin nuchus 'neck' .
The species used to be considered a subspecies (Ssp.) Of the spotted wool back ( Thamnophilus punctatus ) and called Thamnophilus punctatus atrinucha .
features
The bird is medium-sized, has a small hook at the tip of the beak, the male is slate gray with a black crown, the tail dark with white tips, the female brown with a maroon crown. Both have white spots on the tail and elytra . Young birds already look like adult birds after two months, but can be distinguished by behavior and vocalizations. If only briefly sighted , the species can be confused with the dark gray ant catcher ( Cercomacroides tyrannina ), which is also found in the same habitat , but has a slimmer beak without hooks and less white on the wings.
Geographic variation
The following subspecies are recognized:
- T. a. atrinucha Salvin & Godman , 1892, nominate form - South Belize and Northeast Guatemala to Northwest Peru and Venezuela
- T. a. gorgonae Thayer & Bangs , 1905 - Gorgona Island
voice
The call is described as a rolling nasal sequence emphasized on the last note and as similar to the tie ant strangler ( Thamnophilus doliatus ).
Way of life
The food consists mainly of insects , which are often sought in mixed hunting communities in the thicket. When migrating ants swarms , the shrike can be found on its periphery.
The nest is created in the undergrowth, there is no defined breeding season. The species is monogamous with long lasting pair ties.
Hazardous situation
The stock is not considered to be at risk ( least concern ).
