I love to listen to animal sounds-I especially like watching and listening to a pair of red-shouldered hawks that hunt that part of the woods-they also nest on the cliff below my deck.
The only animal sounds I do not even want to hear are the ones made by the feral hogs and the resident mountain lion.
A couple of times, I’ve heard the kitty’s quiet panting and snarling from the cover of the wooded hill across the road and only about 100 feet from my fence, late at night when taking the dog out. I don’t know whose hair stood on end first, mine or the dog’s, but I grabbed her muzzle so she wouldn’t growl, and hauled her and myself back indoors post haste. There is a reason feral cats and dogs don’t last long out here...
I like looking for owls when I hear them. They only call during the day if it’s very overcast. And the answer to what kind of animal made that weird noise is 9 times out of 10 a squirrel.
