A few times recently I have been down at Juanita Bay Park when the eagles have been hunting. While everyone thinks of bald eagles eating fish, they are also happy to eat birds if available. We have had large flocks of coots on the lake and they are a plentiful food source. They stay close together on the surface but, when the eagles fly close, the flocks will get startled and start fluttering around as they try to evade the predators.
The eagles are not bothered about the flock. They just want to isolate one of the birds which they can then take out. They will swoop around until they can take out one bird which they then land on top of and sit on it while it drowns. Once it has stopped moving, they take off and carry it back to the pole in the bay where they can eat at their leisure.
Before you eat a coot, you need to pluck it. The eagles make quick work of this and, with a breeze blowing, the air is quickly filled with feathers as they clean up their kill. Once that is done, time to tuck in to dinner. A coot is quickly eaten and then they fly off to a log to wash up before retiring to a tree to rest and digest. If there is anything left of the carcass, you can guarantee that the crows will be paying close attention and will close in to take care of matters.

We went through a phase at Juanita Bay when the number of coots really rocketed. They were a popular source of food for the local eagles, but they had to work for it. The coots were gathered in large groups on the water and the eagles would do their best to get one isolated so that they could pick it off. As they got close, the flocks of coots would get startled and would start flying around to evade the eagles. Watching this action from a distance was fascinating as this large number of birds tried to move as one to protect themselves. Not a time for being independent!
