Why bird chirps at dawn?
As long as people think that bird song at dawn is to bring happiness to mankind. But science has spent on this myth. Where we know that twitter morning is to control the place and also a sex symbol. The combination of beautiful voices issued at dawn in the mating season is the result of male birds Monologues for females. Tones fall between the sound of one section and complex layers of sound and multiple tones, and chime sounds strongly and beauty that they are friendly to the human ear.
The advantage of bird song in the early days of spring as a sign of the male establishment nesting areas, where acting superbly strong and to announce their presence in a particular area. Voices ring in the sky before and during the mating season, then gradually eased when the young hatch and gradually subside when you grow up young and abandon the region.
And able male bird, in the mating season of the massive effort through its note has indicated a ornithologists during his research in habits bird "Alsgnj" a bird singing, the bird per of this type singing more than 2300 songs in one day, and that is established area nests, until you start female interested in mating access, then reviewed by the male starts voice and physical to convince the female that he liked.
This stage lasts several days before they accept female and actually begin mating male starts to violence sometimes to keep opponents away from his area. But fortunately, and despite all the conditions are mating, and this bond lasts for one semester when some birds, but some large birds, Kalpdja for example, continue with the same partner for life.
Scientists point out that 90% of songbirds monogamous, that is, they stay with one partner, but some other species multiple marriages, where male paired with more than female (2 or more), or the female mating of two males or more. Research indicates that the most beautiful jealous by Dawn is issued by the male birds that practice this type of deception. Vngrad bird Chadi "Alhazj" for example - a type of immigrants, the mating season has short - an unusual and varied depending on what he is doing activity. When the bird alone, looking for female, singing songs long attracted quiet, and to secure the acceptance of female mating, so start singing songs of love and defend the nest, short condensed. However, multi-species Alazaug him, while male wants to attract another female, begins to move to the maximum extent of his area, so keep away as possible from the nest the first female partner. And starts again long complex Baltgrad. So you think any female passers-by chance that he is still lonely and he has a good location to build the nest.
But usually deception-side, when the male returns to the first female partner, you may find another male has been replaced by. The birds flytrap and sparrows movements the same deception that we mentioned earlier. The second sparrows not Bngridha known pleasing, but is famous for her monotonous voice, who is participating Coors Dawn distinct impact.
A group of scientists studying long about a colony of birds league in favor of the U.S. Institute for Scientific Information in Philadelphia. The completed studies in the year 1993, where they found that this kind characterized by dedication, as they noted that parents in a nest are mother and son, in a nest other, they found that only two of the three young resemble their father in terms of match fingerprints, although They all share the same mother. The scientists took a sample from the blood of a number of the periodic males nearby revealed that the father of a small Third, is the live bird nest soon.
It remains for us to say Hallelujah
