Dowitchers

The short-billed one comes through our county in small numbers in May and again end of August, in groups of 1-3. The long billed can be found in large groups in the fall. It took me 7 summers to find one. I found them in Washington state before, where large groups of a different subspecies gather on the coastal mud flats.

I don't seem to have a handy photo of the colorful spring birds, but here is one. 

The grayish winter birds are common, and easy to distinguish from the more squat and more colorful Wilson's snipe.
