At the Chehalis WA tourist operation, there's an eagle's nest that can be seen if you look toward the rear of the train on the bridge over the river at the end of the Saturday evening runs to Ruth. They're easy to spot when they're there.
That said, eagles aren't that uncommon in that neck of the woods.
I'm reminded of the last time I was at Kennedy Space Center with some pals. The tour bus stopped at a eagle's nest and everyone did the ooh-ah thing. I didn't even look over. As we got off the bus, the tour guide asked me where I was from. "Washington state, why?" asked. She said, "Ah, that makes sense. I can always tell when I have someone on the bus from where there plenty of eagles..."
I've been to Juneau AK a couple of times and I swear they're like pigeons are in other big cities, they're everywhere.
