Blue-Chested Hummingbird

Hummingbird

Trochilidae

General appearance

Hummingbirds are small, vibrant birds with iridescent feathers. They are most noticeable for their quick, darting flying style and ability to hover in mid-air. Colors range widely, including greens, blues, purples, reds, and whites, often with a metallic sheen. They possess a long, thin beak perfect for sipping nectar from flowers.

Male vs female

Males are typically brighter and more colorful than females, often with a ‘gorget’ or patch of bright, iridescent throat feathers that females lack. Female hummingbirds have softer, muted coloration for camouflage when nesting. Males are also slightly smaller on average.

Juvenile

Juvenile hummingbirds resemble their mothers in colouring to stay camouflaged. They lack the iridescent throat patch of adult males. As they mature, juvenile males begin to develop more vibrant feathers, particularly on their throats, and by their first winter, most will have at least a few bright feathers indicative of their gender.

How to tell the Hummingbird from the Blue-Chested Hummingbird

Visual differences

The Blue-Chested Hummingbird is visibly smaller, weighing 0.13-0.17 oz and measuring 2.8-4.3 inches, compared to the typical hummingbird range of 0.06-0.85 oz and 2-10 inches. It displays a metallic green upper body and a dark green to blue lower body, with distinct white tail spots. Both sexes have similar coloration, though males have more vibrant blue chests. In contrast, general hummingbird species exhibit broader color variations, including reds and purples, with brighter, more colorful males and typically muted females. Both feature long, thin beaks suited for nectar feeding.

Key differences and behavior

Hummingbirds, a diverse group with over 350 species, including the Blue-chested Hummingbird, exhibit distinct behaviors. Hummingbirds are highly migratory, inhabiting various climates from rainforests to deserts. In contrast, Blue-chested Hummingbirds, found in Central and South America, are short-distance migrants and prefer humid lowland forests. Both feed primarily on nectar, but when nectar is scarce, Blue-chested Hummingbirds fiercely defend feeding territories. Hummingbirds perform elaborate courtship displays, with males leaving post-mating and females solely responsible for nesting. Both species construct small nests, but Blue-chested Hummingbirds use lichens for camouflage. At feeders, both enjoy sugar-water but match their preferences to natural nectar sources. In terms of social behavior, Blue-chested Hummingbirds occasionally form leks, singing in groups to attract mates, highlighting their slightly more communal nature compared to the solitary-focused general hummingbirds.
