The black-crested antshrike (Sakesphorus canadensis) is a passerine bird in subfamily Thamnophilinae of family Thamnophilidae, the "typical antbirds". It is found in tropical South America in Trinidad, Colombia, Venezuela, the Guianas, Brazil, and Peru.
In 1760 the French zoologist Mathurin Jacques Brisson included a description of the black-crested antshrike in his Ornithologie based on a specimen that he mistakenly believed had been collected in Canada. He used the French name La Pie-Griesche de Canada and the Latin name Lanius Canadensis. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognized by the International Commission on Zoological Nomenclature. When in 1766 the Swedish naturalist Carl Linnaeus updated his Systema Naturae for the twelfth edition he added 240 species that had been previously described by Brisson in his Ornithologie. One of these was the black-crested antshrike. Linnaeus included a brief description, used the binomial name Lanius canadensis and cited Brisson's work. This species is now placed in the genus Sakesphorus that was erected by the British ornithologist Charles Chubb in 1918.
