Birds behaviour project is launched
A project to find out more about how birds behave in the wild has been launched.
Researchers want to find out how birds change from one year to the next, and how long they survive for.
The team has been trapping and tagging birds at the Blair Drummond estate in Stirling to find out more about their individual condition.
The birds are fitted with a ring bearing a unique number, which allows researchers to identify them if they are re-caught. The birds are weighed and measured, and their age and sex is also recorded.
It is hoped that the same birds will be retrapped next year, when they will be examined again and the two sets of data compared.
The findings will help the team monitor the condition and lifespan of individual birds, and build up a picture of how long they survive in the wild.
They are then able to feed their findings into a conservation strategy.
The project has no fixed end point and the team hopes to collect as much information as possible about individual birds as it can.
It involves a research team from Glasgow University, the Tay Ringing Group and the British Trust for Ornithology, and began in autumn last year.
So far, about 400 birds have been tagged. They include common species such as blue tits, great tits, robins and blackbirds, but also summer migratory species such as willow warblers and whitethroats.
