This hummingbird lives in the Atlantic Forest of South America. Males raise a purple-blue crest during courtship, while females lack the crest and are green and grayish-white. It feeds on nectar and insects.
Males have a long purple-blue crest, yellow-green upperparts, and a deep purple-blue patch from throat to belly. Females lack the crest and dark underpart patch and are green above and grayish-white below.
It uses forest understory, scrub, riparian vegetation, and farms with remaining woody cover. Males sing and display their crests at leks along forest edges. It feeds on nectar and insects.
