CLOSED: Sandpipers

I have too many sandpipers that I am not quite sure about. If they cannot be ID'ed, that's ok. These were all taken in central Iowa.

1. Least Sandpiper??
2&3 Greater Yellowlegs??
4. ???
5. Yellowlegs??

Here's more...

6. ??? With Blue-winged Teal. This peep seems so big.
7. Solitary Sandpiper or Greater Yellowlegs???
8. Yellowlegs?

OOPS... #8 will be in the next one. I clicked the wrong button.

Here is number 8.

I was so glad to find a Spotted Sandpiper. That was easy to identify after all these others. :)

Thank you for your help.

#1 - Could be, but too blurry to be sure!

#2-3 - Yep, Greater 'legs

#4, 5, 6, 7 - Lesser 'legs

#8 - Greater 'legs

Thank you for the reply. Disappointing, but that's ok. There have been a lot of the Yellowlegs lately, so hoping for others. :)
