The heart has two atria and two ventricles, and the number of beats is rapid. In addition to the lungs, the respiratory organs also have multiple air sacs to assist breathing, so that the bird has oxygen through the lungs during both inhalation and exhalation, that is, double breathing.

HummingbirdsThe smallest bird in the world is called "hummingbird". Hummingbirds grow in Central and South America. Its body is a little larger than that of a bee, and its mouth is long, like a slender tube, that reaches into flowers to collect honey.

Hummingbirds go out in search of food during the blooming and lush vegetation season, and feed on nectar and small insects. The hummingbird builds a nest on the branches, and the nest is made of silk and looks like a delicate wine glass hanging from the branch. Female hummingbirds lay one or two eggs at a time, only the size of a bean, each weighing only one gram, and about 200 hummingbird eggs are the size of an ordinary egg.
