Hummingbird or Rufous-Tailed Hummingbird?
Here's how to tell the difference
Hummingbird
Rufous-Tailed 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.

Amazilia tzacatl
General appearance
The Rufous-Tailed Hummingbird measures roughly 10 to 12 cm in length. Primarily bright green, it flaunts a reddish-brown and slightly forked tail, from which it gets its name. A white spot behind each eye adds to its allure. Its bill is straight and noticeably reddish in color.
Male vs female
Males and females are indistinguishable by plumage, both boasting the same vibrant green and reddish-brown tones. However, females may be slightly larger in size. During mating seasons, males perform impressive airborne displays to appeal to females.
Juvenile
Juvenile Rufous-Tailed Hummingbirds sport similar coloration to their adult counterparts, making them difficult to distinguish. They might show a more uneven, fluffier feather arrangement and their tail feathers can be shorter. They gain full adult plumage within several weeks after leaving the nest.

Visual differences
Hummingbirds (5-10 inches, 0.056-0.85 oz) display diverse iridescent colors with long, slender beaks for nectar feeding. Males are more vibrant, featuring a distinct iridescent gorget, unlike females. Rufous-Tailed Hummingbirds (3.5-4.3 inches, 0.16-0.19 oz) have a predominantly bright green body with a distinct reddish-brown, slightly forked tail. Their beak is straighter and reddish. Both sexes share similar plumage. A characteristic white spot adorns each eye. Rufous-tailed hummingbirds are slightly larger than many typical hummingbird species, with a more aggressive feeding behavior.
Key differences and behavior
Hummingbirds, with around 350 species, generally exhibit territorial feeding behaviors, hovering near vibrant flowers for nectar and consuming insects. In contrast, the Rufous-Tailed Hummingbird measures about 3.5 to 4.7 inches and distinguishes itself by defending feeders aggressively but becoming sociable once sated. While both inhabit tropical and subtropical regions, Rufous-Tailed prefer humid lowland forests, extending to degraded habitats. Hummingbirds perform elaborate aerial displays for courtship, with males departing post-mating; their nests are well-camouflaged. Rufous-Tailed also showcase aerial displays, but males establish territories, building compact nests in semi-open areas. Both lay two eggs, with diligent female incubation lasting about two weeks, plus care for chicks post-hatching. Their diet is similar, featuring nectar and insects, but Rufous-Tailed are noted for versatility in garden ecosystems.
