The subspecies' vocalizations fall into two groups, T. m. melanocrissus through T. m. granadensis and T. m. semifasciatus through T. m. major. The first, found in Central America and mostly west of the Andes, may represent a separate species from the other, which are found east of the Andes. In addition, differences within the members of each group may not be significant enough in some cases to warrant subspecies status. == Description == The great antshrike is a large…
