Even with the slightly different distance on these two photos, I'm pretty darn sure those are not the same bird - facial pattern on the left side of the head (the bird's left) - white cheek patch looks larger on the bird in the photo on the right ...

I had checked out here on Saturday and Sunday and didn't see a falcon, but today Rose and I went around noon and we saw one falcon. The falcon looked like it was the same one we saw last week. We also saw and talked to Dan and a co-worker from Manitoba Conservation and said they were checking the tower on their way back from Shilo. 8)

I'm a bit confused now, TPC. I thought that North American peregrine falcons only nested on the side of rock cliffs or in cities in man made nest boxes with gravel. Would a peregrine falcon actually consider taking over a raven's nest? I thought only Merlins would do that. :-\

Ravens like some of the same human-made structures that peregrines like - towers are one of them, there are lots of birds in the US that nest on all sorts of towers. When Zeus and Alice decided on the Tower Site, the only place they could lay their eggs safely was in the raven's nest. And I should mention (though I think RCF might have mentioned it sometime earlier) these nests are not small - last year's nest was about the size of the McKenzie Seeds nestbox and more flat than nest-like (bowl shaped). In this case the catwalk was like a cliff, the raven's nest the only spot with a solid surface on which to lay an egg. So that's where they nested.
At the University of Manitoba one year a pair tried to nest in a rain gutter and on the Hotel Fort Garry and at the Provincial Legislature, Abby and Garry used pigeon feces instead of pebbles to keep their eggs from rolling off the ledge. They were successful but never returned at the Leg, but spectacularly unsuccessful at the Hotel Fort Garry. In both cases they were too stress being so close to the Radisson Pair (T-Rex and Madame - both highly territorial birds).

Zeus and Alice nested on a lower catwalk last year and the falcon I saw today wasn't in the raven's nest, it was lying down beside it. I don't think it was going to take over the raven's nest, and like TPC said, the falcon may have just been trying to stay cool and not trying to nest.
The falcons that nested in trees in Poland, was I believe, adaptation to their surroundings. If there are no cliffs then they would probably find the best suitable high point, which was a tree.
Link to reply from TPC about the Poland falcons adapting to their enviroment.
