The taxonomy is highly complex and it often includes C. canivetii, C. auriceps, C. forficatus, C. assimilis, C. gibsoni and C. melanorhynchus from north-western South America and Central America as subspecies.
The Garden Emerald is classified as Least Concern. Does not qualify for a more at risk category. Widespread and abundant taxa are included in this category.
