There were quite a few Least Sandpipers around, The yellow legs and long drooping bill give them away. This one is redder than the field guides show. The second is a little less red. They are brown during the winter.
The black legs and short, thicker bill make this a Semipalmated Sandpiper. You can also make out the partial webbing between the toes.
The Stilt Sandpipers are easy to ID in the spring.
The white feather edgings on the tertials and back make this a Long-billed Dowitcher. The Short-billed Dowitcher has gold feather edgings in spring.
I think this is a first spring female Wilson's Phalarope molting into breeding plumage.
That was fun. I need to take advantage of these low water levels in the coming days.
