What birds eat | What forest, predatory and migratory birds eat

Birds in the process of their life consumes a very significant amount of energy therefore, the issue of nutrition for them is vital. Food should not be significant in weight, but to provide nutrients at the proper level, and without unnecessary nontranscious ballast.

Many birds feed on fruits and seeds, but, in fact, only a few of them are able to do with plant foods. Mostly in the diet of a large number of birds, animal food of different species prevails.

Types of nutrition

Birds belong to the class of animals, including more than 10 thousand various species. And, of course, each of them is distinguished by its own preferences in the feed sphere. This choice depends on the habitat of the bird, its size, strength and abilities, the number of competitors and the abundance of food.

In general, it is customary to separate three categories of birds according to the method of their nutrition:

  • carnivorous;
  • vegetable;
  • omnivorous.
  • Bird feed

    Most species of birds are customary to be divided based on their diet into several categories.

    Predator birds

    These are hawks, eagles, owls and others.

    This group includes birds whose food is based on a wide variety of living organisms: rodents, fish, insects, birds, reptiles and much more.  At the same time, birds of prey hunt for prey, or are able to eat carrion.

    Farmousness is called the general term that is used to describe the meat diet, but each species of birds has a specialized diet.

    For example, a certain type of meat preferred by a bird is customary to divide them into:

  • Ichthyophages (tones, penguins, pelicans and others).
  • These are birds whose diet consists of, as a rule, of fish, but also includes a variety of water insects and crustaceans. Such birds can even be distinguished by appearance many of them are distinguished by the specialized structure of the beak and claws that allow them to successfully seize the prey.

  • Insectivorous swallows, woodpeckers, olups and others.
  • These are a variety of birds, in the diet of which, in the large part, includes insects (water, flying, crawling, and the like spiders and grasshoppers).

    Such food is the main sources of protein for such birds in particular, it matters for chicks and young birds.

    Many of the birds are only customary to be considered insectivorous but in fact they feed not only insects, but also invertebrates, which prevail in the diet.

    Some of the species of birds choose insects as food only at that time, when another type of feed is simply unavailable.

  • Poultryjackets, which include sappsans and hawks.
  • Such species of birds include those whose diet forms meat of other, small, birds. Regardless of the size of the predator, they are able to consume other birds, being mobile flyers. The structure of their body (claws and legs) is formed in such a way as to provide an ideal opportunity for hunting and holding production.

  • Molluscular kuliki, kite, sometimes ducks.
  • The diet of this species of birds is usually a huge number of mollusks snails, mussels and even slugs. Such birds are usually characterized by sharp, strong beaks, which provides not only a convenient search for prey, but also the ability to crack it.

  • Snake-eater-a secretary bird, heron and some raven.
  • The serpentry mainly feed on snakes, as the name understands. Such birds are characterized by highspeed reflexes and, as a rule, with sharp claws for a successful hunt for these dangerous reptiles.


    Personable birds, unlike predators, feed on products of exclusively plant origin vegetables, fruits, seeds and the like.

    Based on food preferences of such birds, it is customary to divide them into the following species:

  • Farmday, which includes waxwood, drozds, starlings and many other species.
  • In the food diet of such birds, fruits (apples, pears, tropical fruits) and berries are included in its main mass. Thanks to the special structure of the beak, which is easy to cope even with the most mature massive fruit and remove the skin without problems, these birds have no problems with nutrition.

  • Graintower, an example of which are various chicken and sparrows.
  • Grain poultry feeds with seeds and grains: their dimensions and strong beaks allow not only to dig the grains, but also to split their shell. Small species of birds, whose thin beaks make it possible to eat and extract seeds from cones and even flowers to such birds.

    The diet of many grain birds also includes insects as an additional source of the required amount of protein.

  • Nectar-hummingbirds, tanagras-medoosos.
  • Nektaraydny birds feed mainly by nectar but sometimes they are able to consume very little fruits and juice, as well as insects. Birds of this species can be distinguished by a specific beak, which provides an opportunity to get to nectar.


    They are considered ducks, woodpeckers and even hummingbirds.

    AllUnited birds include those species that feed on vegetable and animal foods. A preferred source of food for such species is attached to fish, lizards, rodents, grass, fruits and much more. I wonder what such a diet is able to change it all depends on the number of products and season.

    The percentage of feed

    Birds have a specific energy exchange therefore, they are forced to consume a huge amount of food. It is small birds that consume especially a lot of food, since such crumbs differ in significant heat transfer due to small body parameters. For example, Korolek, who weighs about 6 grams, is able to destroy at least 30% of this weight of dry matter per day, but the starling is only about 12%. Bird metabolism proceeds at an incredible speed meat and fruits are very quickly absorbed.

    The diet of birds includes a variety of foods both animal and plant. Many birds have a highly specialized orientation in food, and just the opposite omnivorous of them are very, very few.
