The shop where I work at is still in a rural setting, we have a large field behind the shop and tall pines and firs nearby. It's not uncommon to see quail, eagles and all sorts of wildlife. There has been a mating pair of Redtail Hawks in the area for many years.
Several years ago, there was a huge commotion out back, so we stepped outside to see what was going on. There was a huge mob of Ravens swarming around the male Redtail Hawk as he was flying along, carrying a Raven chick in his talons. As he fended off the attacking Ravens who numbered well over a dozen, he dropped the chick into the field near our helipad and started climbing upwards, the flock in hot pursuit. We went over to investigate the chick and it was still alive, though in bad shape. A few of the Ravens swooped on us, intent on defending the chick, so we moved back to the shop to watch the Hawk above fending off the furious attackers and to avoid being pecked at or pooped on, by a couple of angry defenders who were watching over the injured chick.
All of a sudden, from the right, came the female Redtail Hawk. She was coming in low and hot and nailed the Raven chick in her talons with an explosion of black pinfeathers. Keeping low and still travelling at a fairly good clip, she cleared the far fence and climbed up towards a tall pine tree that they've used for nesting, to the west of the field.
This happened so suddenly, the Ravens were caught off guard and had no time to react. With the female Hawk safely in the tree with the Raven chick, the male Hawk went on the offensive and started attacking the Ravens with a fury, killing several and eventually driving them off.
It was an amazing sight to see, the co-ordination between the two Hawks using deception and speed to beat the odds against superior numbers.
