Crimson-collared tanager
species of bird

The crimson-collared tanager (Ramphocelus sanguinolentus) is a species of bird in the family Thraupidae, the tanagers and allies. It is found from Mexico to Panama.
Taxonomy and systematics
The crimson-collared tanager was formally described in 1831 with the binomial Tanagra (Tachyphonus) sanguinolentus. In 1850 Charles Lucien Bonaparte transferred it to the genus Ramphocelus that had been erected in 1805. In 1873 Philip Sclater and Osbert Salvin erected the genus Phlogothraupis with sanguinolentus as its sole member. As of September 2026, the most recent lists by major taxonomic systems assign it to Bonaparte's Ramphocelus. However, it appears to be less closely related to the other members of the genus than they are to each other.
The specific epithet sanguinolentus is from the Latin sanguis, which means blood.
The crimson-collared tanager has two subspecies, the nominate R. s. sanguinolentus (Lesson, 1831) and R. s.

Why this record matters
“Crimson-collared tanager” is worth following because a concise public description often conceals a longer documentary argument. Here, Crimson-collared, tanager and species provides the most credible route into that argument.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 15, 2026. The linked authority identifier is Q1589936. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1831, 1850, 1805 and 1873.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
