There are nearly 10,000 species of birds, and there are more than 1,000 species in China. They have different feeding habits. some feed on plants (mostly on various plant seeds); Some feed on a variety of insects; Some are carnivorous (which can be divided into carnivorous and fishivorous types), and there are many intermediate and omnivorous types.

The feeding habits of birds are the result of long-term evolution and are related to their body size, organ structure (such as beak, etc.); It is also related to the food of the habitat**. Once a bird's eating habit is formed, it is not easy to change easily.

The most typical example of an animal changing its feeding habits is the Australian fly. Flies used to feed on garbage droppings, but because Australia's natural ecological conditions are good, the urban environment is clean and tidy, and there is no exposed garbage droppings, so Australian flies now suck plant juice, chew young leaves and fruits of plants for food, and collect nectar to do the work of bees to transmit pollen.

The pigeon does not eat insects because it feeds its offspring with "pigeon milk" and does not need to catch insects to feed the chicks. Some (but not all) parrots feed their chicks with chewed pulp, which is also considered vegetarian; Ostriches and emus feed on young grass and rarely eat insects; The real insects-free bird is the South American musk pheasant, which eats only a few kinds of leaves from small to large and barely touches other food.
