Distribution
South America: found only in Peru and Ecuador where found west of the Andes and in the Marañón valley.
Taxonomy
Moved from genus Sakesphorus to genus Thamnophilus.[1][2][3]. shumbae split by some authorities as Maranon antshrike.
Subspecies
Two subspecies are recognized:
- T. b. bernardi:
- T. b. shumbae:
- North-central Peru (Río Marañón drainage in Cajamarca and Amazonas). Compared with nominate, male with more white on face and smaller dark throat patch but (perhaps) darker upperparts. Female is paler than nominate and almost white below. It has a brighter rufous crown[7].
Some authorities recognize two additional subspecies, piurae and cajamarcae.
Habitat
Dry forests, dry and moist shrubland.
Behaviour
The Collared Antshrike presents as a species leading an existence that doesn't really stand out very much.
They tend to conduct their food search closer to the ground staying from the ground up to 10 meters / 30 feet above the ground in areas that could be described as thick and/or matted.
While they are prone to living within a particular area, there is no documentation presently available to their doing anything, in particular, to augment being territorial.
They are usually found in pairs but are sometimes in with flocks of other species.
Diet
Finds its food in vines and other tangles, mostly low over or occasionally on the ground. Food consists of invertebrates and occasionally may take vertebrates or fruit.
Breeding
The nest is made from dead grass and stems. It's a deep cup-shaped, loosely woven structure. So loosely woven as to a viewer may see what's inside when looking at it from the exterior.
Into this nest is laid 2 or 3 off-white eggs marked with shades of brown. The female is typically the one incubating the eggs for a period of a couple of weeks, on average.
