(Cambridge, Ontario, Canada)
Our home in Hespeler (Cambridge, Ontario) backs onto a deciduous forest and large marsh which is connected, via a strip of forest, to the Speed River valley.
Every night the Coyotes can be heard howling in the marsh and forest, which I would estimate is at least a 10 acre space.
Typically they are what sounds to be approximately 150 metres away, however recently we have heard them directly behind our fenceline.
I love the sound ..... a large part of the reason we bought the house was the fact that we had wildlife in our view while still in the city.
