VOICE:
Barred Antshrike pair utters wide variety of songs and calls as contact sounds, such as crow-like cawing “arrrr”, a slow “hoo-hoo”, and series of 6 to 8 nasal “kyow”, rising and falling.
Song is an accelerating series of numerous “cah” or “cow”, ending with strong, nasal “graaaaa”.
When Barred Antshrike utters its song, it stretches the neck, erects its crest, and produces vibrations on its semi-fanned tail by wagging it rapidly.
HABITAT:
Barred Antshrike is common in semi-open areas such as dry forests and wooded savannahs, humid to semi-arid second growth, forest edges and thickets. Rarely seen in dense forest, it may be found from 100 to 2,000 metres of elevation.
RANGE:
Barred Antshrike is resident from southern Mexico to northern Argentina east of the Andes Mountains.
It is widespread in Brazil, but confined to the bushy edges of rivers and islands.
BEHAVIOUR:
Barred Antshrike usually feeds in mixed flocks, between low bushes and treetops. It gleans in foliage for invertebrates, catching high diversity of arthropods. They occasionally may follow army ants.
They are usually seen in pairs, at about one to six metres high, well concealed in foliage. Both mates call frequently as they move around.
Male in alert erects its crest.
FLIGHT:
