Poet Liz Berry has been sailing the Shropshire Union canal on a narrow boat since she was young. She describes the canal winding out of Wolverhampton into beautiful emerald green cuttings, where if you're lucky you might see a kingfisher. The canal's shallow and slowly moving waters are perfect hunting grounds. For Liz the azure and copper flash of a kingfisher darting low across the water is a magical sight.
