The bird can cruise at a maximum speed of 30 miles per hour and can clock up to 60 miles per hour in a dive which is quite amazing for so tiny a creature. Hummingbird eggs are just 1/2 inch in size and form almost one-tenth of its body weight. This tiny species needs a food intake equal to half of its body weight. Its diet consists mainly of nectar in flowers, insects, spiders and sap or juice from broken fruits.
