“
As Goblin rushes forward to reconnoiter, Mustard approaches him with a large fear-grin and tries to embrace him for reassurance. Goblin moves forward quickly to a vantage spot to peer across the valley, and Mustard now emulates him. As Goblin (alpha), Satan (number two), and Evered (number three) scan the valley, they break off several times to look at one another quickly. After nearly 60 seconds Goblin suddenly makes his decision, and begins to vocalize and display. The entire group, which includes adolescents Freud and Beethoven, immediately follows suit, and the result is the usual one: both groups vocalize and display ferociously, then slowly retreat into their home ranges.
