Defending Food Sites
Hummingbirds must eat more than their weight in food each day. They meet this need by eating often. No wonder they vigorously defend flowers and feeders!

"Two hummingbirds were alternately feeding and chasing one another off the feeder. Each would rest briefly in the nearby trees before flying in for another round of feeding and fighting."
