Physical charateristics

The male has a grey face, a black throat and a band of large black spots across its white breast. The back shows large buff spots, the tail is brownish with a white tip and there are 3 distinct buffy-white wing-bars as well as buffy tips to the tertials. It has a semi-concealed white dorsal patch which can be seen in the 4th photo. The legs are pinkish and the iris greyish. The female is similar but has a white throat with black malar stripe, has buff wing-markings and is mostly ochraceous below.

Range

South America : Amazonia

Habitat

It is found in the undergrowth of humid forest where it is usually found foraging within 3 metres of the ground.

Reproduction

The nest is a thick, messy, fungal rhizomorph and rootlet cup (with much dead leaf debris attached) slung between two horizontal branches arising from the main trunk of small saplings. The two sides of the nest were attached to branches. Nests are often situated at or near the bottom of 3?5 m deep depressions and 0.75?8 m from small streams. Clutch 1-3 eggs, this differs geographically, incubated by both parents, with only female at night. Both care and feed the young, which fledge after 12-13 days.

Feeding habits

It is usually foraging within 3 metres of the ground. It is not normally found with mixed flocks nor does it follow antswarms as a rule. Feeds on insects, mostly spiders and beetles, often in small related family groups. Dart sallies and perch-gleans for prey.

Conservation

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
Spot-backed Antbird status Least Concern
