Use the information below to answer the
following item.
Hummingbirds need large amounts of energy to flap their wings between
60 and 200 times per second. Their wings beat so rapidly that it is difficult to see them move. They
often appear suspended in air for extended periods of time without changing their location.
Hummingbirds have long bills and grooved tongues to reach into flowers to feed on flower nectar. They
also feed on insects.
