Found in northern Peru, the marvelous spatuletail is a species of hummingbird inhabiting secondary forests and montane scrublands. They are sexually dimorphic as the males are bigger and have longer feathers. While both males and females exhibit green, white and bronze colours on their feathers, only males have blue crest feathers and turquoise gorgets. Their diet consists mostly of honey and flowers. They are threatened by habitat loss due to illegal logging and agricultural expansion.
