Detalhes da observação
This is a typical lowland N. a. acunhae. The bill is relatively thin and pointed with a straight (rather than convex) profile, typical for small-billed birds. Genetically, there is no distinction between lowland small-billed birds (acunhae) and upland small-billed birds ('fraseri') and the only obvious phenotypic difference is that upland birds are more yellow, while this is typically drab. (However, the color difference is likely just an effect of different diets, with upland birds eating Nemertea berries, and N. a. acunhae and N. a. 'fraseri' could be synonymized.)
