The swans have entered another phase of life: moulting. Unlike most other birds, ducks, geese and swans lose all their flight feathers at once, rendering them flightless for a period. And I am capitalizing on this by collecting some of their majestic, sword-like feathers that they leave behind.
Feathers grow from follicles in the skin (like hair) and the growth of a new feather from the bottom of the follicle pushes the old one out. A comparison of feather wear shows that dark colored feathers wear out more slowly than white ones.
