Common Raven Defends Nesting Territory

4-5-13 raven chasing red-tail2 IMG_8693Common ravens are known for their aerial acrobatics, often doing rolls and somersaults and other amazing tricks.  According to Cornell Lab of Ornithology, one bird was seen flying upside down for more than a half-mile. Young birds are fond of playing games with sticks, repeatedly dropping them and then diving to catch them in mid-air.  The pictured raven, however, was much too busy to be doing cartwheels in the sky.  It has a nest with eggs nearby, and during its morning patrol encountered a red-tailed hawk which it drove out of sight in a matter of seconds.  Although small mammals make up most of a red-tail’s diet, they are known to also prey on smaller birds, including defenseless nestlings, which the ravens will have in the next few weeks. (Because of the angle, the  24-inch-long, 53-inch-wingspread raven looks disproportionally larger than the 19-inch-long, 49-inch wingspread red-tail.)
