Tweet Take 5 : Grey Heron

With it's prehistoric looks and tuneless clattering the grey heron is a familiar sight along many rivers and wetlands. More often seen lazily flying away as you draw close, grey herons are also a regular garden visitor to well stocked garden ponds, where standing motionless for hours they wait for that perfect moment to catch their prey. In this extended edition of Tweet of the Day we hear three stories of the grey heron from; Sir David Attenborough, Welsh poet and playwright Gillian Clarke and ecologist Penny Anderson.
