Animals respond to fearful situations

[Catherine]

Animals respond to fearful situations the same way we do. They know when it is more dangerous and they act accordingly.
It is not unlike how we react after watching a scary movie. They stay in groups or avoid areas where a predator is more likely to be waitng. 
They respond differently during a full moon.

I can understand how they learn to react to frightening situations. I think much of our fear response is learned.
It is sad when the fear is so great that birds feed their young less. It makes them vulnerable and less able to survive. 
Living in a fearful situation is very bad for all of us, animals and people.  This needs more study and more thought.  Does the actual fear cause a bird to feed its young less or does the bird feel less safe to look for food and has less to give its young.

This does need more thought.
