Descripción:
Hummingbirds are an American continent birds, there are about 325-340 species, divided into two subfamilies, the Phaethornithinae and the Trochilinae. Most of this species measures 7.5 to 13 cm. Its name comes of the buzz created by the flapping of their wings, becoming 50 times per second, allowing them to also fly at speeds of 54 km/h, backwards and upside down. These birds have the highest metabolism in the animal kingdom, to conserve energy when food is scarce, they may enter in a hibernation state where the metabolic rate slows down to 1/15 of its normal rhythm. The Hummingbirds are specialized nectarivores and are linked to ornithophilous flowers, varying forms and beak to adapt to the various sizes of the corolla of the flowers.
