The green-crowned plovercrest, also black-breasted plovercrest or simply plovercrest, is a species of hummingbird in the "emeralds", tribe Trochilini of subfamily Trochilinae. It is endemic to Brazil.
Region
Atlantic Forest of southeastern Brazil
Typical Environment
Occurs in the Atlantic Forest biome, particularly along montane and foothill zones where flowering shrubs and trees are abundant. It frequents forest edges, secondary growth, bamboo thickets, riparian corridors, and clearings, and occasionally shaded gardens near forest. The species favors dense understory with reliable nectar resources. It may shift locally following flowering peaks, sometimes descending to lower elevations seasonally.
Altitude Range
300–1600 m
Climate Zone
Subtropical
Ease of Keeping
Beginner friendly: 1/5
This small hummingbird is notable for the male’s flamboyant, erectile green crest used in courtship displays and territorial posturing. It is highly dimorphic: females lack the bold crest and black breast of males. Despite its tiny size, it is fiercely territorial at rich nectar sources. It is often seen at forest edges and can visit shaded gardens within Brazil’s Atlantic Forest region.
Temperament
territorial and active
Flight Pattern
short rapid wingbeats with agile hovering
Social Behavior
Males defend nectar sources vigorously and perform display flights, often showing the erected crest. Courtship involves hovering displays and chases; nesting is a small cup of plant fibers and spider silk placed on a slender branch or fork. The female alone incubates and cares for the young.
Migratory Pattern
Partial migrant
Song Description
Gives thin, high-pitched buzzes and tinkling notes, especially during display. Also produces sharp chips while foraging and chasing intruders.
Plumage
Male with iridescent green upperparts, striking erect green crest, and contrasting black throat and breast with pale gray underparts; tail often with white tips. Female lacks the tall crest, shows green upperparts, grayish-white underparts with faint mottling, and a more subdued facial pattern.
Diet
Primarily feeds on nectar from flowering shrubs, trees, and understory plants, probing repeatedly and defending rich patches. Supplements nectar with small arthropods captured by hawking or gleaning from foliage, providing essential protein. It tracks seasonal blooms and may shift territories to follow peak flowering.
Preferred Environment
Feeds along forest edges, clearings, and secondary growth where floral resources are concentrated. Often visits flowering bromeliads, vines, and shrubs in the mid-story and understory, and may use shaded gardens adjacent to forest.
