I'm going to have to do a bit of snooping and talking to buddies of mine south of the border to find out if there are any Manitoba birds in the mix - not impossible by any stretch - we are nesting north and south of them. Will let you know if I hear anything.
As for endangered species lists - it would just be a state protection as they are completely off the federal recovery lists.
Thank you for the reply, TPC! I would be interested to know if you do hear anything. Since South Dakota is pretty much within the corridor the Winnipeg birds like to travel, I thought it was possible that at least one of them might have decided to look around for a nest site.
And yes, I was referring to state protection, which is still good to have. Some states take it very seriously, some less so.
I don't know the ratio of urban to non-urban sites in the U.S., but it seems that the birds are becoming less and less interested in utilizing, for instance, natural cliff sites.
