  • 371 - The Sparrow's Songs
    2025/04/24

    A faint string of birdsong filtered through closed windows on a recent morning. It was well after dawn, but thick gray clouds made it feel like the Sun had yet to rise. “Song sparrow!” I exclaimed. “They must have arrived overnight!”

  • 370 - The Pulse of a Waking Forest
    2025/04/17

    The grouse drummed again; thumping slowly at first, and then crescendoing into a rapid-fire blur. As his last vibrations dissipated into the still air, another grouse answered from a neighboring territory. The low-frequency sounds are audible from up to a quarter mile away. I’m always amazed by how much I feel their sound instead of hearing it.

  • 369 - Snowshoe Hares Eat Dirt
    2025/04/10

    For three days in the summer of 2018 we worked on this mark-recapture survey along a pipeline access road in the Brooks Range of northern Alaska, gathering data that would help scientists at the nearby Gates of the Arctic National Park estimate snowshoe hare population numbers for this year. Our opinion? The population was high. Almost every trap was full, which meant a delayed lunch, and that sense of relief to find an empty trap.

  • 368 - A Home for Wood Ducks
    2025/04/03

    Listening to a pair of wood ducks explode from a tiny patch of open water in a woodland pond and woo-eek through the woods is a distinctly springtime experience. Wood ducks are uniquely adapted for life in the forest, with strong claws on their webbed toes that allow them to perch on tree branches. Scaring up a pair of wood ducks together is common, because these ducks find a mate on their wintering grounds and arrive home together.

  • 367 - Icy Wonders of Chequamegon Bay
    2025/03/27

    The first ice cave was a wonder to behold. Crouching low, we shuffled into the crack that was the cave entrance. The light from our headlamps danced across the cave walls and highlighted the mass of clear ice that extended from the ceiling to the surface of the lake. As other tour guests took pictures with the glowing ice, I was marveling at the cave formation. Sitting under a low-hanging section of the cave, I began to think about how these caves along Chequamegon Bay are formed.

  • 366 - Loon Behavior on Lake Jocassee
    2025/03/20

    For recording time-activity-budgets for loons, Jay has an app on his phone that is set to beep at 2-minute intervals for an hour. At every beep, the binocular-wielding observers help the recorder mark down the behavior. Was the loon resting, locomoting, preening, foraging, or being aggressive? And was the loon within 25 body lengths of another loon? How many loons? One of the main goals of this research is to compare how loons on the salt-free waters of Lake Jocassee spend their time, versus loons who spend their winter on the ocean.

  • 365 - The Loons of Lake Jocassee
    2025/03/13

    The first day of Loon Camp begins with a count of all the loons on Lake Jocassee, which is why I was now puttering through the upper lake on a pontoon boat with Jay, Brooks, and seven other “loonatics.” With eyes scanning and binoculars at the ready, we spotted solo loons fishing in the deep water, rafts of loons preening near shore, and gaggles of smaller waterfowl like horned grebes, too. Jay kept the tally on his data sheet, and we were free to be amazed by the loons.

  • 364 - Winter Wind and Wildflowers with Lois Nestel
    2025/03/06

    As the snow melts and I enter the melancholy often brought on by mud season, I find myself seeking comfort in the words of Lois Nestel, the founding naturalist, director, and curator of the Cable Natural History Museum. She wrote:

    “Now there seems a desolation and bitterness in the wind as though it mourns the sadness and injustice in the world. But the wind is not governed by political upheavals, poverty or crime. It is as it has always been. Only the listener, the endurer, has changed."
