Crows come home to roost

When I sat down to write this blog, I didn’t have a clear topic in my mind. So, I did what I usually do when I want to think and looked out my office window. Through this window, I can see just the tops of three oak trees which today were covered with crows. I counted more than two dozen with more...

Fall is spider season as orb-weavers spin bigger webs

There's a social media meme that says, “There is no better karate instructor than a spider web in the face.” I don’t know about the karate skills, but nothing makes you swat, rub and dance quite like walking into a web. Just imagine how an insect feels. Growing up in the woods, I have walked...

Scat Chat: What animal droppings can tell us

We call anything an animal leaves behind a sign. It could be a broken branch, a footprint, a scrape on the ground or tree, a nest or other home, their own fur, or even animal parts from their last meal. Of all the signs scattered for our inquiry as to what or why, the scat is my favorite and a...

Eliminating the Competition...Allelopathy in Plants

When we think of the bawdy, overbearing characteristics of alien invasive species, often what first comes to my mind is their early-to-rise, late-to-bed season of growth.
