All photos of different birds are very good. The Long-billed Dowitcher is most common west of the Mississippi. They eat insects and insect larvae and on mudflats they also eat mollusks, crustaceans, marine worms.
if I may... It has become my practice to add a lot of sharpening to just the eyes of birds... it makes the entire photo look much sharper. Consider trying this on your already great photos. Nice work though!
