When spring comes and the snow disappears, it's time for the capercaillie birds to have their special dance party called 'lekking.' The boy birds spread their big tails like fans and make silly noises that sound like coughing and popping. You can say:
- "When the snow melts in spring, the boy capercaillie birds show off by opening their tails wide and making funny popping sounds."
- "At springtime, male capercaillies have a dance where they fan out their tails and make noises like coughs and pops to impress the girl birds."
- "When spring arrives, the male capercaillie birds have a special show: they spread their tails big like a fan and make funny popping and coughing sounds."
These are all fun ways to explain what the capercaillie birds do during their mating time!
