[Tweeters] do eagles use osprey nests?

Since Bald Eagles tend to get down to the business of nesting well before most Ospreys arrive, they certainly have the upper hand.  Eagles tend to like to be high in a tree and Ospreys seem to always want the very top.  This helps provide for different niches, but not always.  I have seen Eagles commandeer (sp?) an Osprey's nest, and it's all over but the shouting.  The Osprey won't seriously challenge the larger, heavier Eagle at this time of year.  Now if the Osprey is on eggs or has chicks, different story.

There are a couple of eagles hanging around an established osprey nest platform on one of the electric towers by the Sammamish slough, near the Willows Run golf course in Redmond.  The ospreys have nested here for years and I'm wondering if these eagles may be staking out a claim for this prime real estate.  If so, it'll be interesting to see what happens when the ospreys return and see their nest occupied.  I've never noticed any competition for this particular site in previous years (of course that doesn't mean it hasn't occurred).  My coworkers and I have enjoyed watching the ospreys raise their kids over the years and I'd be disappointed to see the ospreys displaced; am wondering if this is a normal scenario that occurs between eagles and ospreys.  Does anyone have any information about this nest and/or general information on eagle/osprey nest competition in our area?
