`Birds learn how to build nests`

Birds are far from feather-brained, when it comes to building nests, a new research has shown.



Washington: Birds are far from feather-brained, when it comes to building nests, a new research has shown.
Researchers have found that nest-building is not just instinctive but is a skill that birds learn from experience.

Scientists filmed male Southern Masked Weaver birds in Botswana as they built multiple nests out of grass during a breeding season.

Their findings contrast with the commonly-held assumption among scientists that nest-building is an innate ability.

The researchers found that individual birds varied their technique from one nest to the next. They also saw that some birds build their nests from left to right, and others from right to left.

Also, as the birds gained more experience in building nests, they dropped blades of grass less often, implying that the art of nest building requires learning.

Researchers from the Universities of Edinburgh, St Andrews and Glasgow together with scientists from Botswana say their findings may help to explain how birds approach nest-building and whether they have the mental capacity to learn, or whether their skills are developed through repetition.

Researchers chose the colourful African bird because they build complex nests, which is potentially a sign of intelligence.

Dr Patrick Walsh of the University of Edinburgh``s School of Biological Sciences, who took part in the study, said: “If birds built their nests according to a genetic template, you would expect all birds to build their nests the same way each time. However this was not the case. Southern Masked Weaver birds displayed strong variations in their approach, revealing a clear role for experience. Even for birds, practice makes perfect.”

The study has been published in the journal Behavioural Processes.
