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.

The zoologist and writer Jo Wimpenny shares a story of a close encounter with a red kite in the Chiltern Hills, which swooped in to steal some food. This has become a more common experience in the area with the bird's population having grown by over 1,000% since the 1990s. Jo points out that although the return of a species that lives so well alongside humans won't always be welcomed, it's helpful to remember our shared past, like when hundreds of years ago red kites were valued for clearing streets of carrion and waste.

For ornithologist and wildlife researcher for BBC's Springwatch, Jack Baddams, March is 'siskin season'. As a licenced bird ringer, he puts ID rings on wild birds so we can learn more about their lives. One of Jack's favourite bird encounters while ringing was during a bird ringing demonstration for the public. The crowd was fascinated by a female siskin with its delicate citrus green and yellow plumage, but then she became even more amazing when they discovered she was already wearing a ring of Swedish origin.

Naturalist and TV presenter Mike Dilger remembers spending a bird breeding season 30 years ago surveying the Cetti's warbler. The Cetti's has a secretive nature, and like most birders Mike is more familiar with its explosive song rather than it's appearance, which has been described as ‘someone dropping a saxophone in a reed-bed’. Since Mike's foray into the world of conservation science in the mid-nineties the population of the Cetti's warbler has increased rapidly in the UK, most likely due to milder winters.

CEO of the British Trust for Ornithology Juliet Vickery fell in love with dippers while studying them during her PhD in south-west Scotland. She finds them packed full of character, and perfectly adapted to life between water and land. Dippers have to make sure their complex song is heard above the sound of rushing water, and for Juliet the combination of bubbling bird song and bubbling brook is completely magical.

In 2024 and 2025 expedition leader and film-maker Roland Arnison kayaked along the west coast and isles of Scotland to find and record the sounds of seabird species. As part of his quest he stopped on the island of Lunga, a protected area for its breeding seabird colonies and incredible place to spot them. One night Roland climbed the cliffs to find a colony of Manx shearwaters and recorded them calling from their burrows.
