The chest is forward-curving and the entire upper body is dark gray-brown, with the wings being a darker color.
The young ones are similar in appearance to the adults but they are a little bit lighter in color "with plumage fluffier, secondaries and upper wing-coverts edged with light cinnamon, bill pale; immature also like an adult, but bill horn-brown, edges of secondaries and wing-coverts paler".
This bird is not documented to do migrations and tends to stick around the drier areas and move through local regions.
[2] The chiming wedgebill species is not considered "Vulnerable" because its range is very large, and even though its population is getting smaller, the decline isn't fast enough to meet the criteria for being at risk.
Essentially, the species' range, population decline, and size are not extreme enough to be labeled as endangered or vulnerable.
