The impact small wind turbines placed on homes and business could have on birds and bats is to be studied by researchers at Stirling University.
The study will look at the number of the animals killed by micro-turbines, why they may fly towards the machines and possible effects on nesting.
Species which may be affected include those that take insects from the air, such as swifts and house martins.
Those that nest in buildings, such as starlings, could also be in danger.
