General appearance
The Blue-chested Hummingbird, a colorful creature, has a metallic green upper body. Its lower body varies between dark green and blue. It has bright white spots on its tail feathers and a slender, straight beak ideal for feeding on nectar.
Male vs female
Distinguishing between a male and female Blue-chested Hummingbird can be challenging as both sexes share the same colorations. However, males are usually more luminous and have more blue on their chests compared to their female counterparts.

Selasphorus rufus
General appearance
The rufous hummingbird measures about the length of 3 1/2 inches or 9 cm, similar to a sparrow. It boasts an array of colors: black, green, orange, red, and white. Its wing and tail shapes are varied, being narrow, rounded, and short, with multiple points, notches, rounded edges, and square tips.
Male vs female
The adult male is distinguished by a bright coppery rufous color above with a dark throat that glistens red in favorable light. In contrast, females and young sport a green back, a spotted throat with an orange-buff wash on their sides and at the tail's base, presenting a more variegated look.
Juvenile
Juvenile rufous hummingbirds share similar physical attributes with the females, with a green back, a spotted throat, and an orange-buff wash on the sides and tail base. It is likely these colors help them blend into their surroundings for protection, since their eye-catching adult coloration is not yet developed.

Visual differences
The Blue-Chested Hummingbird (3-4 oz, 3-4 in) features metallic green upper parts, dark green to blue underparts, bright white tail spots, and a slender, straight beak. Males are typically more blue-chested than females. In contrast, the Rufous Hummingbird (2-4 oz, 3.5 in) has a coppery rufous back, a dark red throat in males, and varied wing and tail shapes. Females and juveniles exhibit a green back, spotted throat, and orange-buff sides. Both species share some green but differ in beak shape and color intensity.
Key differences and behavior
The Blue-Chested Hummingbird and Rufous Hummingbird exhibit distinct behaviors and habitats. The Blue-Chested Hummingbird is a short-distance migrant from Central and South America, often forming leks and performing aerial displays. It prefers humid lowland forests and consumes nectar from heliconia and insects. In contrast, the Rufous Hummingbird, known for its aggressive behavior, undertakes extensive migrations up to 2,000 miles, primarily inhabiting North American forest edges and mountain meadows. It exhibits territorial aggression, especially over feeders, and primarily nests in conifers. Both species feed on nectar and insects, but the Rufous also remembers feeder locations. Breeding involves male displays, with females responsible for nesting and chick care, but Rufous males often mate with multiple females, enhancing their aggressive reputation.
