Hummingbirds
are among the smallest of birds, measuring in the
7–13 cm range. They can hover in mid-air by rapidly
flapping their wings 12–90 times per second. They can also
fly backwards, and are the only group of birds able to do
so. Honeyeaters are important pollinators of many endemic
plants. Honeyeaters come in a veriety of sizes from small
sunbird-like to medium sized birds. Hummingbirds and
Honeyeaters drink nectar, a sweet liquid inside certain
flowers.
