Putting on a Show

"At our vacation home in California, we noticed this male Anna's hummingbird aggressively protecting his territory by zipping between three perches and chasing other hummers away," write Randy and Barbara Steufert of Mason Neck, Virginia. "He would sometimes fly up over 50 feet in the air and do loops, as if he was showing off. When he landed, he would flash his brilliant throat and head colors."
