I was looking through some shots taken January, 2014 at Lake Awassa in Ethiopia. I'm trying to improve in ID'ing these waders. Am I right to think I'm seeing (from left to right) a Black-winged Stilt, a Spotted Redshank, a Wood Sandpiper, and a Little Stint? (It's unfortunate I didn't get any shots where I could see the suspected Redshank's face!)
