  • Finding one elusive bird

    It’s hot and my shirt is sticking to my back. I part scrubby marsh vegetation with one hand and shield my face with the other. Hiking along the margins of Illinois’ only open-water quaking bog, I’m carrying five liters of swamp water in bottles in my backpack, my samples sloshing with each step.

    Collecting wetland water samples is far from glamorous. My feet are wet, my legs caked in mud, and I frequently swat at hordes of mosquitoes as I hike, sometimes with as much as 10 liters of water in my pack. I’m not interested in the water; rather, if all goes well, I will find my samples contain the DNA of mysterious marsh birds, called rails, that breed and migrate through Illinois wetlands.

  • Unearthing a fossorial snake

    To the naked eye, it might appear as though I’m standing in a prairie oasis. Pockets of bright yellow goldenrod bring vibrancy to the sea of towering grasses. There’s not a soul in sight to spoil the serenity. A lone red-tailed hawk scouring the landscape from the top of a dead oak tree is my only companion. It’s not hard to imagine the entire region looking like this prior to European settlement, expanding miles and miles without interruption. I made the two-hour drive from Champaign to this tiny, fragmented prairie to search for an uncommon snake.

  • Celebrating our diversity

    NOTE: This post describes events prior to the coronavirus epidemic.

    It is snowing again, and I turn to look through the bus window as it slowly pulls into the final stop. I hide my face in my scarf, hoping to stop the cold air sneaking in. It has been almost six years since I moved to the Midwest from Taiwan, but I still cannot deal with winter and snow. Once off the bus, I follow footprints to the Wildlife Veterinary Epidemiology Laboratory and push open the glass door.
