Keep in mind, that even with those loses, I believe the survival rates for the species have improved (though some nests might do badly more often than not).
It is wonderful news from Xcel and well and truly above and beyond their responsibility to the birds at their plants. It is perfectly acceptable to project managers to say, "this site just won't work" and remove the nestbox for good. The peregrines are perfectly capable of finding somewhere new, with or without our assistance, though in cases like these, project managers tend to provide them with options nearby in order to retain successful pairs within an existing territory. Good for the birds, good for their fans and good for the project.
I am really glad to hear that the survival rates for peregrines have improved -- they always seem so very low. I know I have read somewhere that power plant nest sites have a better survival rate than any other type of site.
It is great that Xcel is continuing to be so supportive of the falcons, as they have been for many years. And I'm glad that Mandy Rose and her mate will not have to move somewhere else.
I think this is Dad at the nest today:
And this is the turbine in question, after the pigeon spikes were added:
