    First, a new installment of the feather saga.

    The subtle rainbow in the second is nifty.

    The third is also neat. A face (or a few faces) on the weathered wood.

    The last is a tuber-like fungal mystery.

    I believe that the pretty spectrum in the second photograph is a circumzenithal arc assuming the picture hasn’t been flipped over. They’re sometimes called “upside down” rainbows or “sky smiles”, a name I adore. They’re a little less common than rainbows, requiring ice crystals in the air instead of moisture droplets, but aren’t really rare, just not often noticed.
