Taxonomy and systematics
The giant antshrike was described by the French ornithologist
Description
The giant antshrike is the largest antbird, 27 to 35 cm (11 to 14 in) long and weighing 100 to 155 g (3.5 to 5.5 oz). The species exhibits significant
Distribution and habitat
The giant antshrike has a disjunct distribution. The nominate subspecies is separate from the others. It is found from southern Espírito Santo and southwestern São Paulo states in southeastern Brazil south to central Rio Grande do Sul and into northeastern Argentina's Misiones Province. Subspecies B. c. excubitor is found only in western Santa Cruz Department in central Bolivia. B. c. argentina is found in southern Bolivia's Santa Cruz, Chuquisaca and Tarija departments, in northwestern Argentina's Jujuy, Salta, and Tucumán provinces, and in western Paraguay's Boquerón and Presidente Hayes departments.[5][6][7]
The giant antshrike inhabits landscapes that vary geographically, though in all it favors the understorey to mid-storey. In the
Behavior
Movement
The giant antshrike is presumed to be a year-round resident throughout its range, though local movements in response to bamboo die-off are likely.[5]
Feeding
The giant antshrike feeds on a variety of large insects and other
Breeding
The giant antshrike's breeding season appears to vary geographically but is generally within October to December. It makes a large messy cup nest of plant fibers and leaves, typically in a branch fork among dense vegetation about 1.5 to 3 m (5 to 10 ft) above the ground. The usual clutch is two eggs, which are whitish with darkish and reddish markings. The incubation period, time to fledging, and details of parental care are not known.[5]
Vocalization
The giant antshrike's song is a "series that starts with a short trill and continues with a fast series of notes that increase in strength and pitch, leveling out and decelerating at the end".[6] Its calls include a "long, raspy, downward-inflected snarl, often repeated rapidly, and a short even series of abrupt loud notes".[5]
