it was
believed that this
daintiest of birds
found the nectar
of flowers ample
support for its
active life; but
the later methods
of discovering
what birds eat by
examining the
contents of their
stomachs, show
that the hummingbird is an
insect eater of
most ravenous
appetite. Not
only does it catch insects in mid air, but undoubtedly
takes them while
they are feasting on the nectar of the
tubular flowers which the hummingbird loves to visit. Incidentally, the
hummingbird carries the pollen for
these flowers and may be counted
as a friend in every respect, since
usually the insects in the nectaries
of the flowers with long tubular corollas, are stealing nectar without
giving in return compensation to the
flower by carrying its pollen. Such insects may be the smaller beetles, ants
and flies. The adaptations of the hummingbird's beak and long, double-tubed tongue, are especially for securing this mingled diet of insects and
nectar. It is interesting to note that
the young hummingbirds have the
beak much shorter than when mature.
Its beak is exactly fitted to probe
those flowers where the hummingbird finds its food. The tongue has the
outer edges curved over making a tube
on each side. These tubes are provided with minute brushes at the tips
and thus are fitted both for sucking
nectar and for sweeping up the insects.
The natural home of the hummingbird seems to have been in the American Page(121) ?> tropics. Our one species east of the Rocky Mountains with which we are all familiar has a ruby throat. This comes to us after a very long journey each year. One species on the Pacific Coast is known to travel three thousand miles to the north for the summer and back again in winter.

However, I once had the privilege of listening to a true song by a hummingbird on the Pacific Coast. The midget was perched upon a twig and lifted up his voice with every appearance of ecstasy in pouring forth his lay. To my uncultured ear this song was a fine, shrill, erratic succession of squeaks, "as fine as a cambric needle," said my companion.
DisplayImagewithCaptionWidth("text", "comstock_birds_zpage120b", "The nest of the hummingbird is a most exquisite structure; it is about three-fourths of an inch in diameter on the inside and about half an inch deep. It is, in shape, a symmetrical cup; the outside is covered with lichens to make it exactly resemble the branch on which it rests; the inside is lined with the down of plant seeds and plant fibres. The lichens are often fastened to the outside with the silk web of spiders or caterpillars. The nest is usually saddled on a branch of a tree from 10 to 50 feet above the ground. The eggs are two in number and white; they look like tiny beans. The young are black and look, at first glance, more like insects than like birds.
Leading thought—The hummingbird in flight moves its wings so rapidly that we cannot see them. It can hold itself poised above flowers while it thrusts its long beak into them for nectar and insects.
Method—Give the questions to the pupils and let them make the observations when they have the opportunity.
Observations—
1. Where do you find the hummingbird? What flowers was it visiting? At what time of day? Can you tell whether it is a hummingbird or a hawk-moth which is visiting the flowers? At what time of day do the hawk-moths appear?
2. Does the hummingbird ever come to rest? Describe its actions while resting.
3. What are the colors of the back, throat, breast and under parts? How do you distinguish the mother hummingbird from her mate?
4. How does the hummingbird act when extracting the nectar? How does it balance itself in front of a flower? Have you ever seen hummingbirds catch insects in the air? If so, describe how they did it.
5. Describe the hummingbird's nest. How large is it in diameter? What is the covering outside? With what is it lined?
