Deep within the velvet skies of Aetheria, the Ghost-Wings are gathering. Local legends say that to count the flock is to understand the rhythm of the universe itself.
They move as one mind, a shimmering cloud against the void. Don't try to count them one by one. Feel the space they occupy. Can you guess the size of the murmuration? Stay within the 10% threshold to remain in harmony with the flock and to earn a trophy.
Challenge: Estimate the number of birds
Goal: Get within 10% to win the trophy
Watch the murmuration carefully and make your estimate
