Hummingbirds are important flower pollenators. In the neotropics, some
hummingbird/flower relationships have developed to the point where a birds
bill is the same shape or length as the corolla of single flower species.
Some hummingbirds have developed specialized areas on their crowns that
collect large quantities of pollen.

Hummingbirds are particularly attracted to the color red in North America.
You can test this by building hummingbird feeders painted different colors
and counting how often they visit any particular color (you may also notice
that bees, wasps and flies have color preferences as well).

A very good book about North American Hummingbirds is:
Tyrrell, Esther Q. 1985. _Hummingbirds: Their Life and Behavior_. Crown
Publisher, NY.

Bug your librarian until she buys your school a copy.

There is also a really cool website all about hummingbirds at:
