Bee 'backpacks' monitor flights to aid decline research

BBC News coverage of bangor research into pollinator tracking: 

Tiny "backpack" transmitters are being attached to bees so scientists can track their movements.

Experts at Bangor University in Gwynedd began developing the technology in 2015 using bees' wing beats to create an electrical charge.

The charge powers a signal, which can be followed by an overhead drone as the bees fly over a wide range.

Scientists hope tracking them will provide clues as to why some pollinating insects are in decline.
