Range
South America : Colombia to East Brazil and North Argentina
Habitat
It is found in the undergrowth and near the ground in humid forest and seems to be quite a shy bird.
Reproduction
The nest is a lined cup of twigs low in a tree or bush. Two to three reddish-blotched green-blue eggs are laid and incubated by the female alone for 12-13 days.
Feeding habits
The White-necked Thrush mainly feeds on or near the ground on invertebrates, and will follow army ant swarms. It also takes some fruit and berries. `
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.
The White-necked Thrush is distributed from Mexico through Colombia and northern South America with a disjunct population in eastern and southern Brazil and adjoining areas of Paraguay and Argentina.
Migration
Sedentary throughout range.
