Collared Crow

<em>Corvus torquatus</em> is a corvid in the family Corvidae that has not been formally evaluated under current IUCN Red List criteria. Historically, <em>Corvus torquatus</em> was treated as a valid species encompassing what is now often recognized as <em>Corvus pectoralis</em>, and the two names have been used synonymously in some taxonomic treatments. The relationship between these taxa reflects ongoing revisions within corvid systematics. <em>Corvus torquatus</em> is associated with aerial, terrestrial, and aquatic environments within its recorded range. Corvids generally exhibit complex social behavior, tool use, and omnivorous dietary habits. Specific diet, population estimates, population trend, and biological measurements for <em>Corvus torquatus</em> as a distinct entity are not documented in the available records. Biological traits of this species remain poorly documented in the scientific literature. Its conservation status has not been formally assessed, and the taxonomic status of this name relative to <em>Corvus pectoralis</em> warrants clarification in future systematic reviews.
