Diet
Nectar from flowers and flowering trees, as well as small insects and spiders, are its main food. Although hummingbirds are well-known to feed on nectar, small arthropods are also an important part of adult hummingbirds' diet. Arthropods appear to be the main source of protein, minerals, vitamins, providing a protein source since. Their diet may also occasionally include tree sap taken from sapsucker wells. Hummingbirds show a slight preference for red, tubular flowers as a nectar source. The birds feed from flowers using a long extendendable tongue, and catch insects on the wing or glean them from flowers, leaves, bark, and even from spider's webs.
Young birds are fed insects for protein since nectar is an insufficient source of protein for the growing birds.

Famous quotes containing the word diet:
“The pills are a mother, but better,
every color and as good as sour balls.
I’m on a diet from death.”
—Anne Sexton (1928–1974)
“Television programming for children need not be saccharine or insipid in order to give to violence its proper balance in the scheme of things.... But as an endless diet for the sake of excitement and sensation in stories whose plots are vehicles for killing and torture and little more, it is not healthy for young children. Unfamiliar as yet with the full story of human response, they are being misled when they are offered perversion before they have fully learned what is sound.”
—Dorothy H. Cohen (20th century)
“I learned from my two years’ experience that it would cost incredibly little trouble to obtain one’s necessary food, even in this latitude; that a man may use as simple a diet as the animals, and yet retain health and strength.... Yet men have come to such a pass that they frequently starve, not for want of necessaries, but for want of luxuries.”
—Henry David Thoreau (1817–1862)
