Birds in Montana question

Anyone know what kind of birds I can find in the Missoula, Montana area in mid to late May?

Missoula is about 100 miles from me and probably has more or less the same birds as I see here. I'm not a real bird expert but have been shooting some birds and learning, hopefully I'm not misleading you very badly with this. You might find some Blue Jays and perhaps Stellar Jays, though they are not very common here and probably aren't around Missoula either. Robins should plentiful, as well as Western Bluebirds and perhaps Mountain Bluebirds. Humming birds start showing up around mid to late May. There are several of the smaller songbirds that escape my memory now, if you reply to this so I know it will help I will ask someone who I know can list most of them.

If you are willing to travel 50 miles from Missoula to the National Bison range area there are some marshes with Yellow-Headed Blackbirds and/or Red Winged Blackbirds, and there may be swans as well. There are other birds there too, some smaller colorful ones that I can't remember now (did I mention I'm not a bird expert?). There are Red Tailed Hawks and Lazuli Buntings, as well as pheasants. Along the Clark Fork and Blackfoot rivers there should be swans, geese, ducks, Osprey, and Bald Eagles. The Bison Range also has elk, deer pronghorns, whitetail deer, mule deer, bighorn sheep, badgers, and black bear. I almost forgot, there are the Bison too.

Just north of the Bison Range there is the Nine Pipes bird preserve, there are a lot of waterfowl there.
