Christ bird

During the crucifixion of Christ, when his sufferings were severe, the bird flew beak and tried to pull the nails out of Jesus ‘ body. But too little effort was fearless and good crumbs that just traded his beak and blood-stained breast itself. God thanked the little patroness, and endowed her with special properties.

«Christmas» Chicks;

after the incorruptibility of life.

Bird crossbill — small size, up to 20 cm, passerine, distinguished by its dense, stocky stature, a short forked tail, a large head and a special beak halves of which are bent and shifted in different directions, forming a cross.

Why crossbill beak becomes clear when Klest begins to rapidly valuepath seeds from the cones. Nature has perfectly adapted it to the procuring of such food.

They all have similar feeding behavior and habitat. Names talking about small features of the types of preference coniferous forest environment and the presence of white feathers on the sides.

Habitat and lifestyle crossbill

The ancestors of modern Klestov very ancient, there were about 9-10 million years ago. In spruce and pine forests of the Northern hemisphere formed the principal Klestov. Their dispersal depends on the yield of cones, which are the basis of feeding birds.

Therefore, crossbills live in the tundra and steppe areas, make considerable migrations to places rich in food. Known cases when ringed birds were found over 3000 km from the original site.

In Russia live in coniferous forests and mountainous South of the country, the North-Western regions. The bird can be found in mixed forests with a predominance of spruce. In the cedar forests crossbill lives. Enemies crossbill in nature are almost there.

The reason is that due to the constant use of seeds, birds with life itself, «embalmed» and become very unpalatable, and rather bitter to predators. So after the natural death they are decomposed, are mummified, which contributes to their prepared the body with high resin content.

Flying crossbills are good, but to say that Klest – migratory bird, or Klest — resident, is impossible. Rather, Klest — the representative of migratory birds. The wanderings of birds associated with the harvest.

In places, the saturated feed, the birds spend their time in endless lasagna on the trees, the shape of the beak allows the crossbill to do it cleverly, like parrots. This feature and the bright coloring of the feathers, they are called Northern parrots. They rarely go down, and the branches feel confident, even upside down.

To think that crossbill eats only seeds of fir or pine cones is a fallacy, although this is its main diet. The crossbill’s beak tears off the scales, exposing the seeds, but cones only one-third is spent on food. The bird is not troubled inaccessible grain, it is easier to find a new lump. The rest flying to the ground and feeds for a long time mice, squirrels and other inhabitants of the forest.
