Eagles eagle eagles

It's been hard for me to keep up here...lots of interesting things happening. Eagles are proving to be more of a problem than in the past. With the increase in the population of both species, it's not surprising that the conflicts are also on the rise. One nestpole host contacted me to report that the ospreys were gone and eagles were on the nest. But the ospreys have been seen again on the nest with eagles perched nearby. It remains to be seen who will end up on the nest. Eagles used to be considered to be sub canopy nesters , while ospreys are super canopy nesters...but apparently that is no longer necessarily true. The nesting choices of most ospreys may provide greater protection from predation. Many nests are incubating now, new nests are popping up. We also have one male who is shuttling back and forth between two nests and two females. It's happened before, and one female will end up getting the short end of the fish. I suspect one nest will fail. I am also observing a great deal of disturbance from other ospreys too! Too many ospreys fighting for territories and choice nesting spots. As the population increases it also provides greater opportunities for extra pair copulation. Mixing up the gene pool. I am plugging away at reading bands but some ospreys are just not cooperating! Nor is my old car...an expensive repair has slowed me down a bit.
