Grebe people commonly called mushrooms dirty-gray color on a long stalk.The similarity of them were identified as very graceful water birds.More reminiscent of a poisonous mushroom big and little grebe.Bird feathers have a dirty gray.Long neck is crowned by a head with a black and red collar (two bunches of feathers black color), which makes it representative of birds very similar to the famous forest mushroom.
Description
Bird Great Crested Grebe (great crested grebe) is narrow and short wings, and the muscles that they set in motion, make up only ten percent of the total weight (at the gulls, for example, they are heavier than 2-fold).Flight fast, while not quite maneuverable: bird, in contrast to the same sea gulls, can not boast of aerobatics - flies in a straight line only.
landing and take-off as for her, as if the aircraft - it is not easy.However, here the comparison with the seaplane is more appropriate.Bird does not dare to land on a hard surface because it is not able to extinguish the speed, thereby greatly be hurt on the ground.It is worth noting that water greatly alleviates fit, looks like an elementary fall.
Habitats
Bird squad grebes live on the eastern hemisphere of the planet.In southern areas, they are settled in the north - migratory.
Birds in Central Russia arrive in April.Young grebes take only the new nests.But the elderly are mainly justified on the old.Each pair nesting area is quite extensive - several hundred meters in circumference.And his wife jealously guarding.However, if a few good places for nesting, the birds normally live together in colonies.For example, once in the Azov Sea on the island long (this narrow strip of land in length 1.8 km with maximum width of 20 m) zoologists have counted 165 nests.
Grebe Nest - bird nest which is mainly located in such a way that all the vegetation growing up - a reed, bulrush, sedge - it protects from wind, waves, and prying eyes.Also, certainly there should be free access to swim to him the bird.
sometimes work on nest-building birds alternate with mating.It is usually preceded by the construction.Bird Grebe (photo of her are presented in this article), after putting the next part of the building material, the ceremony begins pleasantries.Thus, floating towards each other, they are simultaneously lowered, and then lift their heads.Then, sticking out his chest, abruptly lifted above the water, and each follows the movements of the other, as if in a mirror.Periodically wedding rituals are doing with the stalk in its beak.Watching these birds with their exquisite collar of feathers, remember grandiose movement ballet soloists - too graceful and simultaneously they move.
Reproduction
Grebe - bird, postponed in May 3-4 greenish-white eggs.They very quickly become an olive-brown color of rotting plants located in their nest.Facilitate this and females, covering its masonry plants if briefly leave the nest.It should be noted that the eggs hatch the female and male.In June, the chicks are already appearing.They are already born are wonderful swimmers dive as they are taught to parents.
There is also very interesting - one of the adults slowly passes by kids, holding in its beak food, then - again.And the kids, in turn, try to grab fish.Following grebe dives with her, inviting children to do the same.But young people to follow the example of their parents is not solved.In this case, one of them puts food on the water and is calling from afar, "Kwong-Kwong!"
Chicks crowd rush, and only the best swimmer can get their well-deserved award.Touching to watch as kids, tired from a long swim, crawl back to the parent to rest, after which she, diving, relieved of its precious burden.
Grebe (poultry): the power
Parents striped chicks feed worms, insects, fish.In doing so, they do not give up and crustaceans, frogs, shellfish, but preference is given, of course, fish.Be sure to note one interesting feature: grebes have stomachs can always find a lump of feathers.Grebe - a bird that collects them on the water, and plucks at.This is explained by the fact that they live in the waters where the muddy ground.
you can not find the stones, which other birds swallow to improve grinding food in the stomach.Although some ornithologists disagree commonly occurring statement.They believe that the pen is a kind of lump sieve which holds the bones of the fish.But no matter what the opinion was correct, the chicks from the first days of life from parents to get food and feathers details.
Young grebes become independent at the age of 2.5 months.They are at this time of brown plumage, and are not particularly clear stripes on the neck and head.Adult attire they appear a little later.It should be noted that especially dressy birds in the spring.Two beams of horns (or ears) on the head and the collar around his neck red color form elongated feathers.The top edge of the collar and ears - black color.The wings and back with transverse white stripes - dark-brown color.And the bottom of the trunk - a brilliant white.
value for human
Through its satiny plumage bird Grebe, a photo which you can see in this article, sipped grief.Thus, in the nineteenth century from the skins of these birds began to manufacture clutch, hats, trim for women's clothing, boa.
Interestingly, fishing bird feathers sometimes growing, sometimes - falling.For example, in the seventies of the last century alone, the Akmola region each year on the Moscow market delivered about 100 thousand birds' skins!
great number of grebes died in Western European countries during the next boom, which at the beginning of this century was caused by incredible demand for their products down.Therefore, it is no surprise that toadstools in Europe a few decades ago are rare.Such is the fashion!
