The Blue-Throated hummingbird has been better studied than many of the other southwestern hummingbirds. This hummingbird usually lives along the edges of streams in mountains or canyons. The nest is usually located wherever there is good overhead protection. This species of hummingbird has been known to raise three broods in one season, which is highly unusual among most other hummingbird species.
The Blue-Throated hummingbird is known as a southwestern hummingbird. The breeding range for this species of hummingbird consists of southeastern Arizona, southwestern New Mexico and western Texas. The breeding period for this particular species of hummingbird is April to July. They migrate northward from March to May and southward from August to October.
This hummingbird is the largest of all the North American hummingbirds. This hummingbird weighs 8.4 grams. The Blue-Throated hummingbird is believed to weigh more than the Magnificent Hummingbird is because it has a much longer tail and wings. The male Blue-Throated Hummingbird is unmistakable. Female is similar to female Magnificent Hummingbird but has large white tips to tail and white malar streak. Other hummingbirds are much smaller.
The male of this species is larger than the female. This is highly unusual among other species of hummingbirds. Male hummingbirds are the tiniest warm-blooded animals on the planet. There are several reasons to help explain why females are typically larger than the males. Female hummingbirds are solely responsible for the care and rearing of the young. Therefore, the females need to be a tiny bit bigger to be able to produce eggs, to afford to share their body heat with the eggs while incubating, and to be able to share their food when feeding nestlings. In this species of hummingbird, the fact that the male is larger than the female may suggest that the roles of the sexes are different in this species.
