Bee hive hums recorded to monitor insects' health
Monitoring devices are being put in bee hives across Scotland as part of a project to keep an eye on their health.
The monitors record temperature and use a microphone to record the hum the bees make while working and resting.
The project has already started to show the many different hums bees use to co-ordinate their work.
It is also helping to work out which environmental forces and factors are behind the decline in bees and other pollinators.
