Who’d’a thunk it?

  • Turkey Vultures on a Rainy Day

    These vultures decided to hang out high atop our neighbor’s tree during a recent day-long rainstorm:

    Turkey Vultures - rainy day
    Turkey Vultures – rainy day

    There may be a third vulture on the branch behind the big clump of pine cones near the trunk.

    This seems about as disgusted as a vulture can appear:

    I think that’s a young vulture, without the red face of more mature specimens.

    They spent most of the day there, then flew off about their business. We’re sure they spent most of the next day drying out.

    Taken with the (new-to-me) DSC-H5 and 1.7× teleadapter; no extra charge for the purple fringes.

  • Buck Season

    This eight-pointer was one of two browsing in the back-yard grove:

    Eight point buck deer in velvet
    Eight point buck deer in velvet

    The other was a mere four-pointer. In a few weeks they’ll get all feisty and browse the grove in shifts.

    The notion of a “suburban hunting license”, perhaps with crossbows, may eventually gain traction.

    A few days later, Mary awoke to a great clattering caused by a buck fighting free of the slot between the garden’s mesh “deer fence” and the neighbor’s wood fence, flattening the corner post in the process. A similar encounter a few years ago ended poorly.

  • Monthly Science: Solar Eclipse 2017

    An hour before the festivities started, I lashed together an official NASA-approved pinhole eclipse viewer from available materials:

    Eclipse 2017-08-21 - pinhole projector
    Eclipse 2017-08-21 – pinhole projector

    Although the solar disk showed up fine on the white paper screen, the Pixel’s camera can’t show the notch growing on the left side, even with HDR+ mode in full effect:

    Eclipse 2017-08-21 - pinhole projector - interior
    Eclipse 2017-08-21 – pinhole projector – interior

    As usual for astronomy around here, clouds threatened the outcome:

    Eclipse 2017-08-21 - high clouds
    Eclipse 2017-08-21 – high clouds

    Near the maximum, the skies cleared:

    Eclipse 2017-08-21 - maximum - lens flare
    Eclipse 2017-08-21 – maximum – lens flare

    Although it’s not proof, there’s a definite bite out of the lens flare at about 4 o’clock:

    Eclipse 2017-08-21 - maximum - lens flare - detail
    Eclipse 2017-08-21 – maximum – lens flare – detail

    The maples south of the driveway produced lower-contrast images better suited to silicon sensors:

    Eclipse 2017-08-21 - maximum - shadows
    Eclipse 2017-08-21 – maximum – shadows

    And, although everyone was specifically enjoined not to do this, because UV reflection = blindness, the obligatory solar eclipse selfie:

    Eclipse 2017-08-21 - obligatory selfie
    Eclipse 2017-08-21 – obligatory selfie

    I’m sure similar lens flares count as UFOs in someone’s telling of the tale.

    We planned to dance naked in the yard, but our neighbor’s lawn crew picked that moment to scalp his grass and we chose discretion over valor …

  • Cocooning

    Each of the three Mystery Caterpillars wandered around the aquarium for a few minutes, found a spot surrounded by leaves, and tucked themselves into their cocoons.

    The smallest one went first and probably got the best site:

    Mystery Caterpillar - Cocoon 1
    Mystery Caterpillar – Cocoon 1

    The medium one:

    Mystery Caterpillar - Cocoon 2
    Mystery Caterpillar – Cocoon 2

    The largest caterpillar munched the leaf around the new cocoon and removed some of the silk (?) wrapper. It looks like the caterpillar’s fur falls off and becomes insulation inside the wrapper.

    The large one with mostly black fur managed to bind two leaves together:

    Mystery Caterpillar - Cocoon 3
    Mystery Caterpillar – Cocoon 3

    The Monarch remained calm, well above the scramble:

    Monarch Chrysalis - with skin
    Monarch Chrysalis – with skin

    The caterpillar’s skin (or whatever it is) remained loosely attached to the outside.

    All of which puts me in mind of Della Lu:

    FINAL WARNING!
    PROJECTION WILL SELF-ENCLOSE.
    CONTINUE?

    I wonder what they’re thinking after they type Y E S …

  • Praying Mantis

    It’s the season for large insects, but this Praying Mantis came as a surprise:

    Mary spotted it on the outside of the window screen in the front bathroom. We watched it for ten minutes as it strolled around the screen, all the while keeping at least one compound eye aimed at us.

    If humans were half as tall, those things would be terrifying!

  • Mystery Caterpillars

    This being caterpillar season, we put a mystery egg mass on a Swiss Chard leaf into a small container:

    Mystery Caterpillar - eggs on Swiss Chard
    Mystery Caterpillar – eggs on Swiss Chard

    I think the darker egg was a dud, because two days later they all hatched and ate their egg cases, leaving that one behind:

    Mystery Caterpillar - hatched
    Mystery Caterpillar – hatched

    Mary deported them to the trash, put two on a leaf in an aquarium on the kitchen table, and, eight days later:

    Mystery Caterpillar - 8 days
    Mystery Caterpillar – 8 days

    They’ve been chowing down on spare garden greenery; unlike Monarchs, they eat what’s set before them.

    One has dark “fur”:

    Mystery Caterpillar - black morph
    Mystery Caterpillar – black morph

    The second is lighter:

    Mystery Caterpillar - brown morph
    Mystery Caterpillar – brown morph

    A third caterpillar escaped the trash can apocalypse and also resides in the aquarium, albeit stunted by its ordeal:

    Mystery Caterpillar - pale morph
    Mystery Caterpillar – pale morph

    They’re too bristly to be Wooly Bears. I’m sure they’ll turn into nondescript brown moths.

  • Milkweed Tussock Moth Caterpillars By The Handful

    Monarch butterfly eggs occur in onesie-twosies on each milkweed plant, but Tussock Moths carpet-bomb the leaves with eggs that hatch pretty much all at once:

    Milkweed Tussock Moth Caterpillars - detail
    Milkweed Tussock Moth Caterpillars – detail

    With a population density like that, the plant doesn’t stand a chance:

    Milkweed Tussock Moth Caterpillars
    Milkweed Tussock Moth Caterpillars

    A few hours later, they were gone and so were the leaves! Presumably, they’re traveling across the ground to the adjacent milkweed plants; one or two may find our patio.

    Despite all the egg-laying we saw, we haven’t seen any Monarch caterpillars out there.
