Unidentified Bird Photos

As a novice birder, I haven't been able to identify everything I've seen/photographed. Below are a few birds I'm not sure of. I realize some of these may never be identified, but if you recognize the bird or can narrow my search down, please let me know!

Plattsmouth, NE (Bay Hills Golf Course), June 2008. I can't decide whether this is something mundane like a starling or if the orange stripe is indicative of something more interesting.

Bellevue, NE (Offutt Base Lake), June 2008. I don't recognize this one-there were reports of pied grebes in the area.

La Platte, NE, June 2008. I thought this was a female red-winged blackbird but the beak didn't seem to match ones I have seen. It was on the edge of some flooded fields.

Bellevue, NE (Fontenelle Forest), June 2008. This one reminds me of a house wren, but I haven't seen that many before to know for sure.

Bellevue, NE (Fontenelle Forest), June 2008. I'm guessing this one is NOT run of the mill, but beats me as to what it is.

Bellevue, NE (Fontenelle Forest), June 2008. I'm thinking this is an Orchard Oriole rather than the more common Baltimore Oriole.

Bellevue, NE (Fontenelle Forest), June 2008. Another one I don't recognize.

Bellevue, NE (Fontenelle Forest), June 2008. Is this another house wren?

La Platte, NE, June 2008. I think it's a tern, but I'm not sure which one. It was flying over some flooded fields-one of maybe a dozen seen.

Teddy Roosevelt National Park, ND (North Unit), 2008. This one was seen at the west end of the 14-mile route through the park. The facial markings remind me of a northern bobwhite. It was hopping around along the ground-I got within a couple of feet of it before even noticing it was there!
