Bar-crested Antshrike Thamnophilus multistriatus

A shy bird typically found in thickets and forest edges. Stout bill with hooked tip, like other antshrikes. Male is barred black and white all over, very similar to Barred Antshrike but with barred crown (not solidly dark). Female has rufous cap and upperparts and is entirely barred black and white below. Most often seen in pairs moving furtively through dense vegetation; can be difficult to get a clear view. Restricted to western Colombia. Listen for its accelerating song, similar to Barred Antshrike but with less explosive ending.
