🔥 up of Swan Families in Winter Disrupts Spring

What actually happened
Young Bewick's swans only survive their first spring migration if they stay with their parents long enough. If they lose their parents in winter, they leave later and are unable to keep up with the rest of the population. As a result, there is a greater chance that they will die in their first year of life.
