  • Why Flamingos Are Pink

    Why Flamingos Are Pink
    Oct 8 2026

  • What Birds See in Ultraviolet

    What Birds See in Ultraviolet
    Oct 8 2026
    Birds see colors we can't. With an extra kind of color cone, many birds see ultraviolet light, which reveals hidden patterns on feathers, fruit and eggs. Here's what that world looks like and why it matters to birds. Inside this episode: - A Fourth Kind of Color Cone - Hidden Patterns on Feathers - Fruit, Flowers and Eggs - What We Still Don't Know Sources include the references linked below.

    How Small Birds Survive a Winter Night
    Oct 8 2026
