I find these shots to be so much more difficult than the larger birds. First, they are almost always moving, next the groups are never even, something is always out of focus.
These are Marbled Godwits (long beaks) and Lesser Yellow Legs. In fairness one could be a Dowitcher. The difference is minimal with some.
The details here are important so I have placed all the photographs in a gallery to help view them a little larger.
