Scaly-breasted Hummingbird

Identification

The Scaly-breasted Hummingbird is a small emerald hummingbird measuring 11.5 to 13 cm in length and weighing approximately 8 to 10 grams. Males and females share identical plumage, though females possess a noticeably longer bill. Most subspecies display a mostly black bill with a pink base on the mandible, with the exception of P. c. roberti, which has an entirely black bill.

Plumage varies subtly among the six recognized subspecies. The nominate subspecies P. c. cuvierii, the smallest and palest form, is predominantly bronzy green with a grayish buff belly. The feathers of the underparts have distinctive buffy edges that create a characteristic scaly appearance—the feature that gives this species its common name. The tail is mostly bronzy, with white tips on the outer two or three tail feather pairs. Other subspecies show darker throats, variations in belly coloration, and differences in tail patterning, with P. c. saturatior representing the largest and darkest form.

Range & Habitat

The Scaly-breasted Hummingbird is distributed across Central America and into South America, with populations found in Mexico, Guatemala, Belize, Honduras, Nicaragua, Costa Rica, Panama, and Colombia. Different subspecies occupy distinct geographical areas, from the Caribbean slope of southeastern Mexico through Central America to the Pacific slopes and lowlands of Panama and northern Colombia.

This species favors semi-open to open landscapes and actively avoids the interior of closed forest. It inhabits dry forest, forest edges and clearings, gallery and humid forest, mangroves, secondary forest, scrublands, and gardens. The species typically occurs from the understory to mid-strata levels, though it also forages in the canopy at forest edges. It is primarily found at low elevations but occurs locally at elevations as high as 1,200 meters in Costa Rica.

Behaviour & Diet

The Scaly-breasted Hummingbird is predominantly sedentary but makes local movements to track flowering events. It feeds on nectar from a variety of flowering trees, shrubs, and bromeliads, foraging both by hovering and by perching on larger blooms. The species is notably aggressive, actively defending flowering patches and dominating smaller hummingbird species at food sources. Beyond nectar, it supplements its diet with arthropods, capturing prey both through hawking and by gleaning insects from vegetation.

Breeding occurs during the rainy season, from May through December in Guatemala and May to January in Costa Rica. Males gather at leks to display for females. The female constructs a distinctive cup nest from plant down and spiderweb, decorating the exterior with moss and lichen. The nest is typically positioned as a saddle on a horizontal branch 2 to 8 meters above the ground in a small tree. The female incubates a clutch of two eggs for 17 to 19 days, with fledging occurring 22 to 29 days after hatching. The species produces a loud, variable, continuous warble composed of chips, sharp squeaks, and short trills, with additional vocalizations including a high-pitched descending trill during chases and various other calls.

Best Time & Places to See It

The Scaly-breasted Hummingbird is considered uncommon to locally common throughout its range. The rainy season, from May through January depending on location, offers the best opportunity to observe this species, particularly during breeding season when males are most vocal and active at leks. The species occurs in several protected areas across its range, making these reserves reliable destinations for viewing.

Since different subspecies occupy distinct regions, visitors should target specific areas: the Caribbean slope of Central America for P. c. roberti, the Pacific slope of Costa Rica for P. c. maculicauda, and Panama and Colombia for the remaining subspecies. Look for this species in semi-open habitats with flowering shrubs and trees, particularly in secondary forest, forest edges, and cultivated gardens where flowering plants attract feeding birds.

Photography Tips

Photograph the Scaly-breasted Hummingbird in its preferred semi-open habitats where flowering trees and shrubs provide both subjects and natural perches. Early morning light works well for capturing the subtle iridescence of the bronzy-green plumage and the distinctive scaly pattern of the underparts. Position yourself near flowering plants or bromeliads where the species forages to capture hovering shots and perched feeding behavior.

The species' aggressive territorial behavior can be advantageous for photography; males actively defend flowering patches and will return repeatedly to the same feeding sites. Focus on capturing the longer bill of females and the subtle plumage differences among subspecies if working in areas where multiple forms occur. Use fast shutter speeds to freeze wing motion during hovering, and pay particular attention to the white-tipped tail feathers, which are a key field mark against the darker bronzy plumage.
