Nature Note: Dogs Do It, Too

I like to sit outside the Zoo reading in the summer; there's usually a breeze, and I like watching the people. My favored spot is right outside the wolf habitat in the Children's Zoo, which is populated by red wolves. They have been extinct in the wild, and Lincoln Park Zoo is participating in a breeding program to beef up their numbers and reintroduce them to their previous range.

At any rate, any time an emergency vehicle goes by with sirens wailing, the wolves start howling in response.

I was just outside when an ambulance went by, siren screaming. Someone had tied their dog outside the Dunkin' Donuts across the street, a standard poodle, and sure enough, it started howling.

I guess I shouldn't be surprised.
