Our feathered friends are not mind when building bird nests

The ability to nest in birds is not instinctive, this skill they have to learn from experience, according to some researchers.

Scientists were able to remove the video in Botswana, the country of South Africa, as the males are red-weaver (Ploceus velatus) Willie numerous nests of grass during the mating season and breeding. Their information contrary to the generally recognized scholars on the assumption that the ability of birds to nest is an innate ability.

The researchers found that each bird has its own separate technique for constructing nests, which makes them different from each other. They also saw some birds build their nests from left to right, and the others did the opposite - from right to left. Also, as the birds have gained experience in building nests, they dropped less tufts of grass on the ground, confirming the belief that the art of nest building requires a long learning.

Researchers from the Universities of Edinburgh, St Andrews and Glasgow together with scientists from Botswana noted that their data may help to explain how birds weave their nests and whether they have the ability to learn, or whether their learning abilities are developed through repetition.

The researchers chose to study the question of fiery African weaver (Euplectes orix), which is widespread in the western and north-western part of Africa, as these birds build intricate nests, which are a potential sign of intelligence. But most important of all is that many weavers weave nests - about a dozen nests in one season - which allowed the research team to consider the differences in nests built by the same bird.

Dr. Patrick Walsh (Patrick Walsh) from the School of Biological Sciences, University of Edinburgh, who took part in the analysis, said the following: "If birds built their nests according to a genetic template, then it would be expected that all the birds will build their nests the same way each time. Nevertheless, it was a completely different case. Such birds like African weavers showed considerable variation in their methods, which clearly indicated the role of experience. Thus, even in the example of birds can be said that in any case the practice makes perfect " .

The study was published in the journal "Behavioural Processes" and was fully funded organization Leverhume Trust.
