Volunteers Fan Out in Fog for Annual Bird Count
Dense pre-dawn fog in December was not as much of a hindrance as one might expect. "It was quite calm, no wind to speak of, which makes it easier to hear birds," Mountjoy says. "Even during daylight hours, a lot is based on sounds. At this time of year, the leaves are off the trees, but the vocalizations are often how I first detect them, and often the identification is based on the vocalizations."
In eastern Knox County, a total of 13 people participated in the count, including two of Mountjoy's colleagues at Knox—Jennifer Templeton, associate professor of biology; and Stuart Allison, Watson Bartlett Professor of Biology and Conservation—along with Elena Prado-Ragan '18, who plans to study ornithology in graduate school.
Working in Knox's Green Oaks Biological Field Research Station, Mountjoy and Prado-Ragan used a car stereo to broadcast the call of the Eastern Screech Owl. "We recorded all three of our resident owl species," Mountjoy said. "We also recorded bluebirds and finches, which is a good mixture in the Green Oaks area," Mountjoy said. "Near the lake, we've had both White-Fronted Geese and Canada Geese."
"Because owls are predators, their call can flush the other birds. And if there are owls in the area, they'll respond to the call," Prado-Ragan explained.
"Being a bird enthusiast, this is exactly what I plan to do in the future," Prado-Ragan said. "Jim is so knowledgeable, and you really need someone to guide you through the whole process, because there's so much to learn."
