Birds insectivorous: names

These winged assistants during the feedingtheir nestlings destroy a great many insects. Perhaps, therefore, insectivorous birds are quite deservedly considered to be beneficial to man. Although, for example, the same starlings cause damage during their autumn flights to vineyards and stone fruit trees.

Birds insectivorous

From the very title it is clear what, or rather - by whom,these animals eat. Birds insectivores destroy insect pests, among which are crisps and scoops, weevils and moths, leaf-eaters and whitecaps, aphids and bedbugs, flies and many others. Naturally, insects are their main food (especially during the incubation and feeding of chicks).

Birds are insectivorous. Titles

In the grass, on the ground and in the air all kinds ofpests are collected by starlings and hoopoes, thrushes and finches, cynical birds, sparrows and larks. In the thickets of bushes, tons of insects are destroyed by dawns and wren, warblers. In the crowns of large trees - the Orioles and cuckoo, korolorki and chiffchaff, tits and woodpeckers. And this is far from a complete list of insectivorous birds inhabiting the middle belt.

Some interesting facts

Birds of insectivores sometimes render to mankindhuge services. And if it were not for the labor of these winged assistants, some insect species would have been bred in great numbers, because it is known that this is one of the fastest-growing groups of inhabitants of the planet.

• In the middle of the last century in Scandinavian countriesthe cabbage moth has bred so much that its population is more than 100 million individuals per hectare. Here the birds came to the rescue of man and destroyed an overabundance in nature.
• And in the United States on the Great Lakes in 1975, "fish flies"have reached countless numbers. They even packed in cars and houses, their corpses carpeted streets and coasts with a layer up to 15 centimeters high. Special equipment was allocated for cleaning. And this time the helpers assisted.
• A sparrow being insectivorous, at one timewas almost completely (by order of the government) exterminated in China, as it was considered a harmful eater of cereals. The fields began to swarm with caterpillars, which no one had to destroy, and it took a considerable amount of time to restore the population to its previous norm.
• A kind of control over the number of insects,carried out by insectivorous winged, plays a huge role in nature. Thus, on one hectare of forest (according to studies conducted by Moldovan scientists), seven pairs of insectivorous birds with hatched chicks destroyed about 6,000,000 insects in just 90 days, one third of which are harmful.
