Field crickets are in danger and the Back from the Brink Field Cricket Project team are working to help increase the population of these chunky little crickets which are just 2 cm long. In the 1980s, there was only one group of fewer than 100 individuals left. This is where  cricket ticklers come in – their job is to find and collect crickets from one site and move them to new homes on restored heathland. On this edition of Nature’s Voice Jane Markham finds out more from Jane Sears, the RSPB’s senior reserves ecologist and Martin Fowlie – a volunteer cricket tickler!
