Here's how to tell the difference
Broad-Billed Hummingbird
Blue-Throated Mountain-Gem
Broad-Billed Hummingbird
Cynanthus latirostris
General appearance
The broad-billed hummingbird is a small, vibrant bird known for its vivid coloration and striking bill. It features a broad, red bill with a dark tip, making it easily recognizable. The plumage showcases brilliant emerald green coloration that shimmers in sunlight, complemented by a bluish throat.
Male vs female
Males possess more vivid plumage compared to females, with a noticeable bright blue throat and shimmering green body. Females are less colorful, often displaying a duller green back and a white or greyish throat. Both sexes have the characteristic red bill, although females may exhibit a slightly shorter and less intensely colored beak.
Juvenile
Juvenile broad-billed hummingbirds typically exhibit a duller version of the adults’ plumage. They often lack the vivid blue throats seen in adult males and can display a grey or buff-colored throat. Identifying juveniles in the wild can be challenging due to their resemblance to females, with a less developed, muted color palette.

Lampornis clemenciae
Also known as: Blue-Throated Mountaingem, Blue-Throated Hummingbird
General appearance
The blue-throated mountain-gem is a striking hummingbird with metallic green upperparts and a white breast. Its most distinctive feature is the iridescent blue throat patch that shines brightly in sunlight. The tail is rounded with white tips that are visible during flight, and it has a straight, medium-length bill.
Male vs female
Males are distinguished by their vibrant blue throat, which contrasts with a dark face mask. Their crown is a vibrant green, adding to their striking appearance. Females, however, exhibit more subdued coloration, lacking the blue throat of the males. Instead, they have a buffy throat and grey underparts with a less defined face mask.
Juvenile
Juvenile blue-throated mountain-gems resemble females but with even duller coloring. They lack the male's distinctive blue throat and have additional buffy edging on their feathers. As they mature, young males gradually develop their blue throat. Identifying juveniles in the wild can be challenging due to their muted colors compared to adults.

Visual differences
The Broad-Billed Hummingbird is smaller, measuring 3-4 inches and weighing 0.07-0.14 ounces, while the Blue-Throated Mountain-Gem is larger, at 4.5-5 inches long and 0.21-0.35 ounces. The Broad-Billed has a vivid emerald green body with a red bill and a bluish throat, whereas the Blue-Throated features metallic green upperparts, a prominent iridescent blue throat, and white-tipped tail. The Broad-Billed's bill is broad and red-tipped, while the Mountain-Gem has a straight, medium-length bill. Males of both species display more vivid colors than females.
Key differences and behavior
The Broad-Billed Hummingbird (2-4g, 3-4 inches) inhabits semi-open Arizona habitats, often near streams. It defends its territory actively, with males using vantage points to ward off competitors. In contrast, the larger Blue-Throated Mountain-Gem (6-10g, 4.5-5 inches) prefers shady mountain canyons and streams, subtly defending its territory through mid-level perching and a monotonous squeak. Both species feed on nectar and insects, but the Mountain-Gem can rely on insects when flowers are scarce. Broad-Billed Hummingbirds lower their body temperature on cold nights to save energy, while Mountain-Gems emphasize a duetting courtship over visual displays. The Broad-Billed Hummingbird's nesting is lower and camouflaged with leaves, while the Mountain-Gem uses higher, sheltered sites adorned with green moss.
