Rooster Nest (ornithology)
As Hahn Nest occasionally, side nest called, is known in the ornithology a second nest , built by a number of bird species, besides the actual nest.
For a long time these nests were thought to be the roosting place of the male, and some species of birds have indeed been observed to retreat here. According to other ornithologists, however, the cock's nest serves to mislead enemies of the nest because the actual nest is hidden under the cock's nest. This behavior would be particularly conclusive in the case of African finches , whose breeding parasite is widow birds . Other ornithologists, on the other hand, regard the cock's nest as a functionless structure that sticks out of a misoriented building behavior. For this reason, the more neutral term “side nest” was proposed for these structures.
The species that often build side nests include some species of beautiful finches, such as the red driftwood . In some areas of wave branches , cocks' nests are regularly found, which are built on the actual ball nest as a second, semi-vaulted nest.
