Due to high energy needs, the hummingbird has special gastronomic preferences. These birds feed exclusively on nectar and pollen of plants. These foods are rich in carbohydrates, but poor in protein. To make up for the need for squirrel squirrels eat small insects. Different types of hummingbirds prefer nectar of different plants, some species are so narrowly specialized that they can only eat on plants of the same species! This is precisely what determines the shape of the beak in different species. Hummingbirds are very voracious and for a day eat up the amount of food 2 times the mass of their body.
Northern species of hummingbirds reproduce in summer, tropical species all year round. The male zealously defends his plot, but limits the concern for the continuation of the genus by mating with the female, the rest of the efforts fall on her shoulders. The female builds a nest half-spherical in shape from the finest grass, wool and even cobweb.
The nest is located on the thin ends of branches that are inaccessible to tree predators, sometimes it is attached to leaves and other suitable objects.
