When spring arrives and the snow starts to melt, it is the time when male capercaillie birds show off to find a mate. This special event is called 'lekking.' During lekking, the male birds spread their big tails like a fan to look impressive. They also make funny sounds that can be like coughs or odd popping noises, almost like little party tricks! This helps them catch the attention of female birds. So, in other words, the male capercaillie get ready to sing and dance in the spring to impress the females!
