Some facts about Hummingbirds from defenders.org/hummingbirds/basic-facts:-
Hummingbirds are small, colourful birds with iridescent feathers. Their name comes from the fact that they flap their wings so fast (about 80 times per second) that they make a humming noise. Hummingbirds can fly right, left, up, down, backwards, and even upside down. They are also able to hover by flapping their wings in a figure-8 pattern. They have a specialized long and tapered bill that is used to obtain nectar from the centre of long, tubular flowers. The hummingbird’s feet are used for perching only and are not used for hopping or walking.
Hummingbirds primarily eat flower nectar, tree sap, insects and pollen.
The hummingbird’s fast breathing rate, fast heartbeat and high body temperature require that they eat often. They also require an enormous amount of food each day. Hummingbirds have a long tongue which they use to lick their food at a rate of up to 13 licks per second.
