Evolutionary and Ecological Relationships

Clearly the closest relative of Amazilia violiceps is A. viridifrons, which ranges from central Oaxaca and central Guerrero south to Chiapas. It is thus apparently partially sympatric with A. violiceps and cannot be considered conspecific on the basis of present knowledge.

The only possible hybrids so far reported involving this species are two birds, an adult male and a probable young female. The male, originally described as a new species (Cyanomyia salvini), was later believed to represent a possible hybrid involving Cynanthus latirostris (Bent, 1940). Later it was interpreted as simply an extreme example of A. v. ellioti (Friedmann et al., 1950), but Phillips et al. (1964) evidently regarded it as a hybrid with the broad-billed hummingbird. No identification could be made on the second specimen.

Ecological relationships between this species and other hummingbirds or plants are still unstudied.
