  • Raccoons In the Night

    Raccoons In the Night

    The only reason we haven’t seen a standing raccoon is because we’re not awake when it happens:

    The glowing dot over on the far right is a third raccoon!

    They are athletic critters:

    Mary puts garden clippings in the wheelbarrow before hauling them over the hill to our organic dumping ground. Something must smell pretty good in there:

    The wire mesh over the new plantings in the garden seems to be holding them at bay, but it must come off before it snares the growing plants. We hope whatever is in the fertilizer will have worn off by then!

  • Going About Their Daily Affairs

    Going About Their Daily Affairs

    The fox caught what looks like a small groundhog for supper:

    The tom turkeys have been forming and re-forming their groups:

    The gray cat may have spotted breakfast out there in the yard:

    We haven’t seen a raccoon stand up like this before, so something must be very interesting out there:

    Off to its far right, Mary had fertilized a new pepper planting, which evidently smelled good enough to motivate vigorous digging. None of the plants sustained damage, despite being tossed around, but dexterous paws were surely involved!

  • Chipmunk Sprint Speed

    Chipmunk Sprint Speed

    The trail camera caught a chipmunk with cheek pouches stuffed full of maple seeds:

    Chipmunk Run - 0042
    Chipmunk Run – 0042

    The critter evidently heard something, as it froze in position for some seconds, then launched toward its burrow somewhere on the left:

    Chipmunk Run - 0047
    Chipmunk Run – 0047

    Whatever it heard must have been terrifying:

    Chipmunk Run - 0053
    Chipmunk Run – 0053

    It covered 2 m across the camera field in 1/2 s (15 frames at 30 f/s) for an average speed of 4 m/s = 9 mph from launch.

    A slide show for your edification:

    • Chipmunk Run - 0042
    • Chipmunk Run - 0045
    • Chipmunk Run - 0047
    • Chipmunk Run - 0053
    • Chipmunk Run - 0058
    • Chipmunk Run - 0059
    • Chipmunk Run - 0060
    • Chipmunk Run - 0061
    • Chipmunk Run - 0062

    We know this chipmunk as “Stumpy”, because of its half-length tail, and think it has considerable motivation for outstanding speed.

    Tail high, little one!

  • HW Bucked Lithium AA Cells

    HW Bucked Lithium AA Cells

    The trail camera uses two parallel banks of four series AA cells to get enough oomph for its IR floodlight. I’m not convinced using bucked lithium AA cells in that configuration is a Good Idea, but it’s worth investigating.

    These are labeled HW, rather than Fuvaly, because it seems one cannot swim twice in the same river:

    HW bucked Li AA cells
    HW bucked Li AA cells

    In any event, they come close to their claimed 2.8 W·hr capacity:

    HW bucked Li AA - 2023-05
    HW bucked Li AA – 2023-05

    The lower pair of traces (red & black) are single cells at 2.7-ish W·hr, the blue trace is a pair at 5.4 W·hr, and the green trace is a quartet at 9.8 W·hr. Surprisingly close, given some previous results in this field.

    Recharging the cells after those tests shows they all take 3 hours ± a few minutes to soak up 730 mA·hr ± a few mA·hr, so they’re decently matched.

    Measuring the terminal voltage with a 10 mA load after that charge lets me match a pair of quartets to 1 mV, which is obviously absurd:

    HW bucked Li cells - initial charge 2023-05-05
    HW bucked Li cells – initial charge 2023-05-05

    The numbers in the upper left corner show the initial charge of four cells at a time required the same time within a minute and the same energy within 4%.

    Sticking them in the trail camera must await using up the current set of alkaline AA cells.

    Bonus: a lithium fire in a trail camera won’t burn down the house.

    After all, pictures like this are definitely worth the hassle:

  • Trail Camera: Skunk

    Trail Camera: Skunk

    We’ve never seen a skunk by day, so this was a bit of a surprise:

    Skunk by night
    Skunk by night

    We occasionally smell a skunk by night, but this critter seems peaceable enough:

    Skunk by night - detail

    Skunks usually have a striped back, so this one’s pure white fur will be easy to identify should we meet again, ideally at a mutually respectful distance.

  • The Early Opossum

    The Early Opossum

    Having just deployed a trail camera to see what might be skulking about in the middle of the night, this appeared just before the (not fresh) batteries died:

    The Early Opossum
    The Early Opossum

    It’s hard to tell with possums, but I’d say that critter is on a mission!

    I’m still figuring out proper distances; the possum is about two feet away, which is obviously much too close. Great focus on the water barrels standing by the garage, though.

  • Jake the Turkey Gets Trapped

    Jake the Turkey Gets Trapped

    Another turkey figured out how to get the best seeds from under the bird feeder in the far corner of the patio:

    Turkey tracks on the patio
    Turkey tracks on the patio

    Jake, our affectionate term for whichever turkey is having trouble, eventually walked from right to left closest to the house, down the patio steps, and rejoined the flock. The tip of his “arrow” tracks aims backwards, because all three toes point forward.

    It turns out turkeys panic when they’re behind a barrier and see the rest of their flock moving away. A panicked turkey makes a lot of noise while rushing back and forth, the rest of the flock contributes what must be advice, and the resulting tumult suffices to wake the dead.

    That would be me, in the bedroom off to the left, but my cold-boot sequence takes long enough that I missed the action.

    Some years ago, we discovered how distressed a trapped turkey can get when the flock descended from trees in an adjacent yard, with (a different) Jake landing in the garden, on the other side of the fence from the flock. Over the course of the next several hours, Jake ran back and forth along the fence while the rest of the flock alternated between sympathetic honking and disinterested feeding, until eventually he remembered his wings and managed a short-field takeoff over the fence.

    Never a dull moment around here …
