Just adding some audio so you can listen to the wolf howling Marilyn mentioned.
The PBS show Nova has a page devoted to wolf howling with some more recordings.
yES, OF coarse WOLVES AND DOGS CAN HEAR FREQUINCES THAT MOST HUMANS CANTPosted by: Kelsey
Wendy,Canines definitely can hear higher frequencies than we can but their vocalizations aren't in that range. Can you think of other reasons they might hear ultrasound?Posted by: Larry
That's awesome!! I love hearing them howl! Our last 3 brothers were marvelous at all howling together.:)Posted by: Marilyn
Holy cow, that is fantastic!Posted by: Leslie
Wolves and dogs have such a range in their vocalizations! Do they produce sounds we cannot hear?Posted by: Wendy A
Domesticated dogs, wolves, and coyotes are known to howl at sirens. Our old red wolves did too. Howling is thought to be a way to communicate over long distances ("I'm over here", maybe). Since signals degrade as they travel through the environment, animals often respond to sounds that are reasonably close to the qualities of the call. There is very little cost to responding incorrectly so higher discretion would not be rewarded.Posted by: Larry
Why do wolves howl? Are they trying to contact other wolves? If so, does that mean he thinks the firetruck is another wolf?Posted by: Beck
