It would appear to us humans that two Boat-Tailed Grackles are in a heated conversation. When we talk there has to be somebody or something that listens to us or it becomes pointless. Even if it means we talk to ourselves. There are schools of Psychology where all the therapist does is simply listen to the patient. People have to express themselves and talking is a mainstay of self expression. Ask the yourself this question: Are you a talker or a listener? Listening is something we all should develop. We learn by listening, we stay out of trouble by listening, we build relationships by listening. Does the talker really hear themselves or does the listener hear them. Remember: SOMEBODY HAS TO LISTEN!
