About the Blackish-gray Antshrike

The blackish-grey antshrike (Thamnophilus nigrocinereus) is a species of bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in Brazil, Colombia, French Guiana and Venezuela. The blackish-grey antshrike was described by the English zoologist Philip Sclater in 1855 and given the binomial name Thamnophilus nigrocinereus. It has these five subspecies:

T. n. cinereoniger Pelzeln, 1868 T. n. kulczynskii (Domaniewski & Stolzmann, 1922) T. n. nigrocinereus Sclater, PL, 1855 T. n. tschudii Pelzeln, 1868 T. n. huberi Snethlage, E, 1907 Some authors treated Castelnau's antshrike (T. cryptoleucus) as a subspecies of the blackish-grey antshrike, but that approach was not widely accepted. They are now considered sister species. Some authors suggest that some of the current subspecies might be better treated as species.

The blackish-grey antshrike is 15 to 17 cm (5.9 to 6.7 in) long and weighs 28 to 32 g (0.99 to 1.1 oz). Members of genus Thamnophilus are largish members of the antbird family; all have stout bills with a hook like those of true shrikes. This species exhibits sexual dimorphism. Adult males...
