Tanagers (Thraupidae)

Cherrie's Tanager (Ramphocelus costaricensis) - HBW 16, p. 188

French: Tangara du Costa Rica German: Cherrietangare Spanish: Tangara Costarricense

Taxonomy: Ramphocelus costaricensis Cherrie, 1891, Pozo Azul, Costa Rica.
Often treated as conspecific with R. passerinii, but recent DNA studies suggest that the two 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 vocal differences only minor; further evaluation of these taxa is desirable. Monotypic.

Distribution: Pacific slope of Costa Rica from Puntarenas (C & S regions) and NE Central Valley S to W Panama (Chiriquí and Veraguas).
