Features Insectivorous birds.

Insectivorous birds are of great benefit by eating hordes of insects. For the most part, these insects are pests of agricultural crops. For the extraction of insects, birds have a number of features. Firstly, this is the structure of the beak. It is elongated and sharp. It is thickened at the base, which makes it stronger. For example, a woodpecker. This helps him to get insects from the thickness of tree trunks. Secondly, birds have thin and tenacious toes with sharp claws. With their help, birds are easily kept on plants. Third, some birds have long, sickle-shaped wings, which help to make complex turns in the air, thereby eating more insects. For example, swallows.
