> "Predator!" vs "Predator?" Should have gone with "Friendship!" VS "Friendship?"

  There really are birds that have predator warning calls. Other animals even listen for them and hide when they hear them.

    We can always tell when our neighbor's cat is outside when the birds in our yards start to get agitated.

      I've noticed the warning call differs at times, I hear two chirps for land based predator and three for air. Small sample size, city finches.
