Spooked,
To add to what Chewy said, and agreeing, there also may be a connection with females of the species and crying. As I'm certain you know, women tend to be reactive to crying sounds..... Empathy and curiosity may both play a part. Until we can ask them, it's all guesswork.
As for danger to young ones, I would not be overly concerned, but aware. The noises you hear very often are just them sayin I'm here, or, I want this territory. Like me yelling at the brush turkeys to get them to stop messin up the garden (it didn't work btw), or someone yelling at trespassers. I purposefully am not attempting to get you scared, but being aware of large animals of any kind, and making certain to pass that awareness along to children helps keep ya calm and them safe.
Please take all of the above as opinion, I know I have grumpy days, so I figure our friends have theirs also.
You mentioned farm animals in the area going ballistic. Could you elaborate on this? I'm begining to see more correlation between different animals and their reaction to our hairy friends visiting the neighborhood.
Good Luck on your search to find out more about these guys, but a word of warning..... It becomes addicitvie !!!!
I don't pretend to understand any of this, I'm still trying to figure out the questions to ask.
cheers
