What´s that sound?

I have to mention that during our stay in San Pedro de Atacama we heard some of the weirder sounds we´ve ever experienced.

Example 1- the crying dog. In one of the small towns on a tour we heard this dog wailing, I mean wailing-crying on the street. It didn´t belong to anyone and looked lost. It was just wandering and whining at the top of its lungs. It didn´t sound like a dog at all.

Example 2- the laughing man. Now, hailing from NYC we are used to our fare share of bums, but we found a rather unique bum in the same small town as the wailing dog. He was lying on the street, near the dog, cracking up. I mean seriously seriously laughing. At what? we have no idea, nor did he probably, maybe the dog?

Example 3- the cow. There was some cow that was behind our hotel that would not shut up. Now i feel like I´ve heard cows before in my life, but never have I heard one moo this loud. over and over and over. damn cow
