still more sparrows

Even with your ids on the last two, I still don't know what I'm looking at with these sparrows. Saw this one in the wet grass by the lake and then it flew into the tree. I was at Iron Creek Lake in the Black Hills of South Dakota.

Sparrow 1

Sparrow 2 -- All of these were taken in the Black Hills of South Dakota.

Sparrow 3 -- I labeled this sparrow 3 but I think it was the same bird that is pictured in sparrow 2.

Bird 4 - is this a sparrow? a bunting? a junco? I'm totally lost on this one.

Sparrow 5 - This is probably impossible but maybe the tail pattern is revealing?

Bird 6 - I think this is a yellow-rumped warbler. There were several around.

Bird 7 -- I was going to do a mission impossible thread for the bird pics that I'm pretty sure no one will be able to figure out. This is one of the pics that would have been on that thread, but decided to put it with the sparrows. Bill looks kind of long and possibly curved. Barring on the breast and interesting tail pattern but mostly it's just a blur!

#1 possibly juvenile White-throated Sparrow?
#2 Chipping Sparrow
#3 Chipping Sparrow
#4 Dark-eyed Junco, white-winged subspecies (Black Hills endemic subspecies)
#5 probably juvenile Audubon's Warbler (formerly part of Yellow-rumped W)
#6 ditto
#7 pass!

Very excited about #4. A friend told me to look for that junco and yet even with the heads-up I didn't recognize it when I saw it! Thank you!
