oh, it's Jim. I was wondering where he got to. I was waiting for him by the pond for 2 hours yesterday, and he never showed up.
To be honest, I'm a bit surprised he wasn't photographed in a bar.

I'm going with sharp-tailed grouse for this one. The plumage looks about right when I zoom in for the larger view, and the location would seem to exclude the two prairie-chickens.

I agree with the Sharp-tailed call. Prairie Chickens are all barred underneath (even if the location didn't rule them out). This is in eastern Montana, with little if anything in the way of woods, so even without the plumage we can rule out Blue, Spruce, and Ruffed Grouse. And a Pheasant would have a longer bill, and would lack the streaking underneath. I believe the red just above the lores is also a mark against Pheasant.
