Could it possibly be the site listed above by Suzee? That site is in British Columbia.. Canada.. I suppose there are quite a few.. I've just gotten to know this pair and so I feel connected to them... They are just such beautiful birds. And BIG.. my oh my!
The area they are nesting in is right close to a fish hatchery. What an ideal location.. and it's on private property, so hopefully that will also help protect them.
