In the fall the Bald Eagles start to migrate south. They are not in a hurry to head south and the cold fall or winter does not seem to bother them. The key for their migration pattern seems to follow the open water. As long as the rivers or lakes are not frozen over the eagle can fish. Then it seems they are content in staying in that area. Unlike the Osprey whose diet is 98% fish, the eagle will fish, hunt or scavenge for food depending on availability. They are great at fishing but will also take down a duck, rabbit or even bigger animal. They can lift and carry up to 4 lbs. They do also scavenge animals that have died of other causes (winter, road kill or steal a meal from another animal).
At one time the numbers of this bird dwindled and were on the endangered species list. Mainly due to the poising of predators to help protect the cattle range used for grazing. This practice was outlawed for this very reason. They have had a remarkable come back and now can be seen in most states in the US.
A very majestic and powerful bird, I do enjoy viewing and photographing this bird. A sight to see when one skims the river surface with its claws, only to catch and lift a fish from the water without even getting wet.
