The researchers chose trails in places where dogs were banned and in other areas where dog walking was common, expecting different results in each. “We thought that where there was regular dog walking birds would get used to it,” Dr. Banks said. “Well, they didn’t.”
Regardless of the type of area, dog walking led to a 35 percent reduction in the number of bird species and a 41 percent reduction in overall bird numbers, compared with the control. (People walking alone caused some disturbance, but less than half that caused by people with dogs.)
That's a bit of a bummer.
