Different species of birds vary in their beak shape, body size and the environment in which they live, and they also eat different types of food. Generally, birds can be divided into three categories: carnivorous birds, herbivorous birds, and omnivorous birds.
1. Carnivorous birds: including eagles, vultures, falcons, raptors, owls, etc. These birds mainly feed on other small animals such as small fish, insects, mammals, reptiles and other birds.
2. Herbivorous birds: including pigeons, cranes, swans, geese, ducks, etc. These birds mainly feed on plant foods, such as seeds, fruits, young leaves, nuts, etc.
3. Omnivorous birds: including sparrows, crows, magpies, ornithopods, etc. These birds eat both meat and plant foods such as insects, seeds, fruits, and nectar.
It should be noted that different birds may change their eating habits in different seasons or living environments. Some birds will also adopt different types of food to meet their nutritional needs based on changes in their life cycle and environment.
