Interconnections in the Web of Life
By Randy Comeleo
For the past five years, we have been composting our food scraps with the assistance of red worms in outdoor bins at EPA’s Western Ecology Division (WED) laboratory in Corvallis, Oregon. Last winter, we noticed that large food scraps were being stirred-up overnight by something in our compost bins. We installed a self-operated wildlife camera inside one of the bins and soon identified the culprits: an after-hours party of dusky-footed woodrats–handsome, ash gray packrats with large ears and furred tails–were enjoying the freshly added vegetables.
Over the next several months, our self-operated wildlife camera revealed a continuous nighttime parade of skunks, raccoons, opossums, gray foxes, and coyotes on our WED campus.
A remarkable example of the interconnectedness of species occurred a few weeks ago when we witnessed a female osprey carrying a large fish over our WED property. The osprey lost her grip on the fish when she turned into a strong westerly headwind and the fish landed a few feet from the WED gray fox family’s den site.
The next day, we found the partially scavenged fish on the ground and identified it as a largescale sucker, most likely from the Willamette River, located nearly two miles away.
The fish was soon completely consumed by the hungry little foxes and the event illustrated just how interconnected we all are in the Web of Life.
