Sharptails Plus may have information like this. Reach out to them via their website and speak with Terry.I've been out a few times to the east with a similar story. Couple wing beat, couple fluff and feather piles along roads.
I have not seen as many magpie and jays per trip as usual, but not exactly science.
I wouldn't mind if we had even a part time upland bird specialist. When they weren't letting gov know that there is a dollar to be made in having more than just goose hunters in fields they could pass out a few blood test strips to see how bad, or not, West Nile is in local grouse pop, east and west.
