Aliens have invaded Colorado. Once again, a non-native species has moved into our territory and established a thriving population. In this case, it’s the European Paper Wasp (left). You can read all about it at the Colorado State University Extension website.
In this case, having this new insect in town is a mixed blessing. Although they look a lot like a yellow-jacket, European Paper Wasps aren’t aggressive; they can sting, but they seldom do. On the down side, they’ve been known to go after the sweet juices of ripe fruit such as cherries, and pose a threat to the orchards on the Western Slope.
Specifically, a Penn State biologist named Tomas Carlo studied Japanese Honeysuckle (considered a noxious weed in much of the eastern US) and found that its presence increased the biodiversity of bird species as well as the number of individual birds. In fact, the fall berries are a major source of food for fruit-eating birds.
From the big questions (how many species of birds are there?) to specifics (should the Bullock’s Oriole and the Baltimore Oriole be merged into one species called the Northern Oriole?), birders have long endured a bit of confusion. It seems even the most eminent ornithologists disagree on these and similar conundrums.
