The BBC’s favourite wildlife presenters look back through the archives as they share their most memorable adventures in Britain and Ireland.

Chris Packham remembers a recent filming trip where he had the privilege to spot some extremely rare birds circling the skies above his home county of Hampshire: white-tailed eagles. Gordon Buchanan recalls joining a fishing trawler to film killer whales off the coast of Shetland.

Vianet Djenguet describes his first sight of a cuckoo in Norfolk, a migratory bird whos song Vianet remembers hearing from his childhood in Congo. Chris Packham also remembers a memorable shoot in Norfolk, where he struck gold by finding four grass snakes - and their particularly noxious smell, designed to ward away predators.

Steve Backshall shares memories of filming what he calls 'one of the greatest natural miracles on earth' - seahorses. Colin Stafford-Johnson looks back on an incredible encounter he had with basking sharks in the waters around the Skellig Islands.
