Use the information to figure out and summarize which hummingbirds wings flap the fastest. 

Hummingbirds have compact, strongly muscled bodies and rather long, bladelike wings that, unlike the wings of other birds, articulate (connect) to the body only from the shoulder joint. The architecture of the wing permits hummingbirds to fly not only forward but also straight up and down, sideways, and backward and to hover in front of flowers as they obtain nectar and insects from them. The rate at which a hummingbird beats its wings is the same during directional and hovering flight. It varies with the size of the bird—the larger the bird, the lower the rate. Consequently, the smallest hummingbirds have extremely rapid wing-beat rates. In Calliphlox amethystina, one of the tiniest species, the male has a wing-beat rate of about 80 per second; the female, which is larger, beats her wings at a rate of about 60 times per second. The ruby-throated hummingbird has a wing-beat rate of about 70 per second in the male and about 50 per second in the female. The rate is much lower in the larger hummingbirds; the giant hummingbird, for example, beats its wings only about 10 times per second. In fact, the larger hummingbirds appear to beat their wings more slowly than do other birds of comparable size.

Various hummingbird species beat their wings at different speeds. The larger the hummingbird, the slower the speed of the wings; therefore, the smallest hummingbird's wings flap the fastest. 

Within the smallest species of hummingbirds, the males' wings beat faster as they are smaller than the females.
