|Scientific Name:||Tachyphonus cristatus|
|Species Authority:||(Linnaeus, 1766)|
|Taxonomic Source(s):||SACC. 2006. A classification of the bird species of South America. Available at: #http://www.museum.lsu.edu/~Remsen/SACCBaseline.htm#.|
|Taxonomic Notes:||Tachyphonus cristatus (Sibley and Monroe 1990, 1993) was split into T. cristatus and T. nattereri by Meyer de Schauensee (1966) but this treatment is not followed by the BirdLife Taxonomic Working Group because while the Group accepts it is odd that nattereri, without a throat-patch, should sit adjacent to one in which the throat-patch is bolder than elsewhere, the Group feels the type should be re-examined and the possiblity of age-related or other sorts of variation should be investigated further.|
|Red List Category & Criteria:||Least Concern ver 3.1|

This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). The population trend appears to be stable, and hence the species does not approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size has not been quantified, but it is not believed to approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.

|Population:||The global population size has not been quantified, but this species is described as 'fairly common' (Stotz et al. (1996).|
Trend Justification: The population is suspected to be stable in the absence of evidence for any declines or substantial threats.
|Current Population Trend:||Stable|
