Tanagers (Thraupidae)

Scarlet-rumped Tanager (Ramphocelus passerinii) - HBW 16, p. 187

French: Tangara à croupion rouge German: Passerinitangare Spanish: Tangara Terciopelo
Other common names: Passerini’s/Song Tanager

Taxonomy: Ramphocelus Passerinii Bonaparte, 1831, Cuba; error = Guatemala.
Often treated as conspecific with R. costaricensis, but recent DNA studies suggest that they can be regarded as separate species. DNA studies indicate that both are monophyletic and, although levels of divergence within the two taxa (0·1%, 0·6%) are much less than divergence between them (1·8%), this level of interspecific divergence is lower than that between most species of tanager (c. 2·4–4·0%); also, visual differences between the two are minimal (involving mainly females), and only minor vocal differences have been demonstrated; further evaluation of these taxa may be requir..
