RFI - RMNP and Pawnee

[Peter Crosson]

Hi folks, my friend Tom and I are visiting Colorado from Massachusetts for some birding, starting this coming Sunday. While we have a long list of target birds, I was hoping to ask for some advice on some of the harder to find ones.
We will be spending most of the week in Rocky Mountain National Park, but plan to make a day trip to the Pawnee grasslands. Any advice on specific sites to find the following would be greatly appreciated! I should mention that I purchased Scott Roederer's excellent Rocky Mountain National Park book, but I don't know how up-to-date some of that information is.

In RMNP:
American three-toed woodpecker
Dusky grouse
Brown-capped Rosy-Finch
Flammulated owl

At Pawnee:
Both longspurs

Thanks in advance for any help! Feel free to email me off list at pcro...@emeraldphysicians.com.
