BACKYARD SECRET – WHERE GRAY SQUIRRELS LIVE CAN AFFECT THEIR COLOR
The results of a recently published study conducted in Montreal, Canada by researchers at McGill University suggest where gray squirrels live appears to have an impact on the color of their coats.
According to the stu
dy’s senior author, Allison Roth, the amount of forest cover and other factors found in urban areas seem to affect the color of the animals’ hair. The researchers learned that the squirrels inhabiting those neighborhoods in the city with colder winter temperatures and more trees are more likely to display black coats. In comparison, squirrels that live in the more urbanized and warmer areas of Montreal were more likely to have gray coats.
According to the author, “People often think of cities as a single type of environment, but our findings show that conditions animals experience can vary dramatically from one neighborhood to another,” Roth went on to say, “These local differences, along with barriers such as rivers, can shape how wildlife populations evolve, which means we need to look beyond simple urban-rural comparisons to understand adaptation in cities.”
HELP NEEDED TO TRACK THE SPREAD OF THE JORO SPIDER
The University of Georgia’s Center for Invasive Species and Ecosystem Health is tracking the spread of the invasive Joro spider across the State of Georgia. With that in mind, the researchers are asking the public to document its march across the Peach State.
“You can’t just have the experts looking for them,” says the center’s Rebecca Wallace. She went on to say, “Photos from the public help researchers identify new habitats and collect specimens for further research.”
Another goal of this study is determining if this large spider is having any impact on native wildlife. Many Georgians are afraid the Joro spider’s webs are catching ruby-throated hummingbirds and butterflies such as the monarch.

BACKYARD SECRET: ONE-WAY CHIPMUNKS WARN OTHERS WHEN A PREDATOR IS NEAR
Chipmunks are common residents in Georgia yards. While they can be regularly seen during the warmer months of the year, at no time are they more often seen than from late summer throughout autumn. This is the time when chipmunks are busy gathering and storing food for winter.
As you might expect, this is a time when they are more likely to cross paths with predators. When one chipmunk sees a hawk, fox or other predator they warn the other chipmunks in the area that danger is close by. Remarkably, they warn their cohorts when a predator is near using two distinct calls. One is uttered when an aerial predator is close by. A totally different call is vocalized when the threat comes from a ground predator.
Now that is pretty neat!
