The female of this particular species is slightly larger then the male. These hummingbirds live in Cuba. Its body is about the size of a large bee, thus the name of the species. The bill and tail account for half of this length.
Like all hummingbirds, the bee hummingbird is known to be strong and swift flier. This species of hummingbird also spends a higher percentage of their lives flying than any other species. They have specially adapted flight muscles, which make up 22 to 34 percent of their total body weight. Just like other hummingbird species, their shoulder joints allow their wings to rotate 180 degrees and their small feet and legs can only be used for perching.
