Festive Coquette

Is a minute hummingbird species measuring between 7.5 and 8.5 cm in total length and weighing roughly 3 grams. The taxon displays pronounced sexual dimorphism in plumage ornamentation and chromatic patterns. The adult male features a prominent, short forehead crest of glittering emerald-green, flanked by elongated cheek tufts that are iridescent green tipped with distinct whitish spots. Its dorsal region exhibits a warm bronzy-green hue, interrupted on the lower back by a conspicuous transverse creamy-white band. The throat shines with brilliant green iridescence, merging into a dusky or blackish abdomen. In contrast, the adult female lacks both the erectile cranial crest and the elaborate cheek plumes; she possesses a faint whitish malar streak, a pale throat heavily spotted with dark discs, and a whitish breast washed with buff. The bill is short, straight, and measures around 13 mm, showing a reddish-pink base with a sharp black tip.

Geographical distribution: Is predominantly endemic to the coastal and montane belts of southeastern and eastern Brazil, closely tied to the remnants of the Atlantic Forest biome. Its range extends across the states of Bahia, Espírito Santo, Minas Gerais, Rio de Janeiro, São Paulo, Paraná, and Santa Catarina. Marginal and historical occurrences have been cited in extreme northeastern Argentina within the province of Misiones, representing potential vagrants or low-density peripheral populations in contiguous riverine corridors.

Habitat: Occurs predominantly within the canopy and subcanopy of humid lowland evergreen forests, moist montane forest interiors, mature secondary woodlands, and clearings rich in flowering vines. It generally ranges from sea level up to elevations of around 1000 meters. The species also colonizes shaded agricultural plots, flowering tree plantations, and ecotonal forest borders where rich epiphytic communities provide suitable microhabitats.

Feeding: Employs an opportunistic nectarivorous and insectivorous diet. It gathers floral nectar by visiting scattered blossoms, showing an affinity for plants belonging to the families Fabaceae (notably Inga species), Bromeliaceae, Rubiaceae, and Myrtaceae. To satisfy vital protein and amino acid needs, it regularly catches aerial micro-invertebrates by hover-hawking or gleaning small spiders, gnats, and minute wasps directly from the underside of leaves and bark crevices.

Behavior: Operates primarily as a low-density trapliner, traversing established circuits between scattered floral resources rather than defending feeding territories against larger dominant hummingbirds. Its flight is notably slow and deliberate while hovering, frequently shifting with lateral swaying motions that closely mimic large sphingid moths or bees. Individuals perch quietly on exposed, leafless twigs in the upper canopy to rest, survey surrounding patches, and preen their ornate feathers.

Nesting: Nest construction, incubation, and brood rearing are undertaken exclusively by the solitary female. She weaves a diminutive, cup-shaped structure utilizing fine plant down, silk cotton, and tree-fern fibers, bound together resiliently with spider webs. The exterior wall is decorated with lichens and bits of bark, rendering it virtually invisible against tree boughs. The typical clutch comprises two white elliptical eggs. Incubation lasts approximately 13 to 14 days, and the female broods and feeds the nestlings via regurgitation for about 20 to 22 days until fledging occurs.

Conservation status: Is currently evaluated as Near Threatened (NT) on the global Red List maintained by the International Union for Conservation of Nature (IUCN). The primary driver of its population decline is the ongoing deforestation, extensive fragmentation, and habitat degradation that plagues the Atlantic Forest due to logging, urbanization, and agricultural expansion.
