Velvety black tyrant
species of bird

The velvety black tyrant (Knipolegus nigerrimus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is endemic to Brazil.
Taxonomy and systematics
The velvety black tyrant was formally described in 1818 as Muscicapa nigerrima, placing it in the Old World flycatcher family. It was later transferred to genus Knipolegus, which was erected in 1826 with the blue-billed black tyrant (K. cyanirostris) as the type species.
The velvety black tyrant's taxonomy is unsettled. The IOC and BirdLife International's Handbook of the Birds of the World assign it two subspecies, the nominate M. n. nigerrimus (Vieillot, 1818) and M. n. hoflingae (Frederico Lencioni-Neto, 1996). The Clements taxonomy does not recognize hoflingae, treating the species as monotypic.
This article follows the two-subspecies model.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Velvety black tyrant”, the useful work is to connect “species of bird” to the records capable of establishing context and consequence.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Oct 5, 2025. The linked authority identifier is Q1269863. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1818, 1826 and 1996.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
